Leprosy, also known as Hansen's disease (HD), is a chronic disease caused by the bacteria Mycobacterium leprae and Mycobacterium lepromatosis.^[1][2] Named after physician Gerhard Armauer Hansen, leprosy is primarily a granulomatous disease of the peripheral nerves and mucosa of the upper respiratory tract; skin lesions are the primary external sign.^[3] Left untreated, leprosy can be progressive, causing permanent damage to the skin, nerves, limbs and eyes. Contrary to folklore, leprosy does not cause body parts to fall off, although they can become numb or diseased as a result of secondary infections; these occur as a result of the body's defenses being compromised by the primary disease.^[4][5] Secondary infections, in turn, can result in tissue loss causing fingers and toes to become shortened and deformed, as cartilage is absorbed into the body.^[4][5][6]

Although the mode of transmission of Hansen's disease remains uncertain, most investigators think that M. leprae is usually spread from person to person in respiratory droplets.^[7] Studies have shown that leprosy can be transmitted to humans by armadillos.^[8][9][10] Leprosy is now known to be neither sexually transmitted nor highly infectious after treatment. Approximately 95% of people are naturally immune^[11] and sufferers are no longer infectious after as little as 2 weeks of treatment.

The minimum incubation period reported is as short as a few weeks, based on the very occasional occurrence of leprosy among young infants. The maximum incubation period reported is as long as 30 years, or over, as observed among war veterans known to have been exposed for short periods in endemic areas but otherwise living in non-endemic areas. It is generally agreed that the average incubation period is between three and five years.

Leprosy has affected humanity for over 4,000 years,^[12] and was well-recognized in the civilizations of ancient China, Egypt, and India.^[13] In 1995, the World Health Organization (WHO) estimated that between 2 and 3 million people were permanently disabled because of leprosy at that time.^[14] In the past 20 years, 15 million people worldwide have been cured of leprosy.^[15] Although the forced quarantine or segregation of patients is unnecessary in places where adequate treatments are available, many leper colonies still remain around the world in countries such as India (where there are still more than 1,000 leper colonies),^[15] China,^[16] Romania,^[17] Egypt, Nepal, Somalia, Liberia, Vietnam,^[18] and Japan.^[19] Leprosy was once believed to be highly contagious and was treated with mercury — all of which applied to syphilis, which was first described in 1530. It is now thought that many early cases of leprosy could have been syphilis^{[clarification needed]}.^[20]

The age-old social stigma^[21] associated with the advanced form of leprosy lingers in many areas, and remains a major obstacle to self-reporting and early treatment. Effective treatment for leprosy appeared in the late 1930s with the introduction of dapsone and its derivatives. Leprosy bacilli resistant to dapsone soon evolved and, due to overuse of dapsone, became widespread. It was not until the introduction of multidrug therapy (MDT) in the early 1980s that the disease could be diagnosed and treated successfully within the community.^[22]

MDT for multibacillary leprosy consists of rifampicin, dapsone, and clofazimine taken over 12 months. Dosages adjusted appropriately for children and adults are available in all primary health centres in the form of blister packages.^[22] Single dose MDT for single lesion leprosy consists of rifampicin, ofloxacin, and minocycline. The move toward single-dose treatment strategies has reduced the prevalence of disease in some regions, since prevalence is dependent on duration of treatment.

World Leprosy Day was created to draw awareness to leprosy and its sufferers.

Classification[link]

There are several different approaches for classifying leprosy; however, parallels exist.

• The World Health Organization system distinguishes "paucibacillary" and "multibacillary" based upon the proliferation of bacteria^[23] ("pauci-" refers to a low quantity.)
• The SHAY scale provides five gradations.^[24][25]
• The ICD-10, though developed by the WHO, uses Ridley-Jopling and not the WHO system. It also adds an indeterminate ("I") entry.^[26]
• In MeSH, three groupings are used.

There is a difference in immune response to the tuberculoid and lepromatous forms.^[27]

Hansen's disease may also be divided into the following types:^[28]:344-346

• Early and indeterminate leprosy
• Tuberculoid leprosy
• Borderline tuberculoid leprosy
• Borderline leprosy
• Borderline lepromatous leprosy
• Lepromatous leprosy
• Histoid leprosy
• Diffuse leprosy of Lucio and Latapí

This disease may also occur with only neural involvement, without skin lesions.^{[13][29][30][31][32][33]} This disease is also known as Hansen's Disease.

Signs and symptoms[link]

Skin lesions are the primary external sign.^[3] Left untreated, leprosy can be progressive, causing permanent damage to the skin, nerves, limbs, and eyes.

Diagnosis[link]

Diagnosis in the U.S. is often delayed because healthcare providers are unaware of leprosy and its symptoms. Early diagnosis and treatment prevents nerve involvement, the hallmark of leprosy, and the disability it causes.^[34]

There are many kinds of leprosy but there are common symptoms. These include runny nose, dry scalp, eye problems, skin lesions, and muscle weakness.

Cause[link]

Mycobacterium leprae[link]

Mycobacterium leprae, one of the causative agents of leprosy. As acid-fast bacteria, M. leprae appear red when a Ziehl-Neelsen stain is used.

Mycobacterium leprae and Mycobacterium lepromatosis are the causative agents of leprosy. M. lepromatosis is a relatively newly identified mycobacterium isolated from a fatal case of diffuse lepromatous leprosy in 2008.^[2][3]

An intracellular, acid-fast bacterium, M. leprae is aerobic and rod-shaped, and is surrounded by the waxy cell membrane coating characteristic of Mycobacterium species.^[35]

Due to extensive loss of genes necessary for independent growth, M. leprae and M. lepromatosis are obligate pathogens, and unculturable in the laboratory, a factor that leads to difficulty in definitively identifying the organism under a strict interpretation of Koch's postulates.^[2][36] The use of non-culture-based techniques such as molecular genetics has allowed for alternative establishment of causation.

While the causative organisms have to date been impossible to culture in vitro, it has been possible to grow them in animals. Charles Shepard, chairman of the United States Leprosy Panel, successfully grew the organisms in the footpads of mice in 1960. This method was improved with the use of congenitally athymic mice (nude mice) in 1970 by Joseph Colson and Richard Hilson at St George's Hospital, London.

A second animal model was developed by Eleanor Storrs at the Gulf South Research Institute. Dr Storrs had worked on the nine-banded armadillo for her PhD, because this animal had a lower body temperature than humans and might therefore be a suitable animal model. The work started in 1968 with material provided by Waldemar Kirchheimer at the United States Public Health Leprosarium in Carville, Louisiana. These experiments proved unsuccessful, but additional work in 1970 with material provided by Chapman Binford, medical director of the Leonard's Wood Memorial, was successful. The papers describing this model led to a dispute of priority. Further controversy was generated when it was discovered that wild armadillos in Louisiana were naturally infected with leprosy.

Naturally occurring infection also has been reported in non-human primates including the African chimpanzee, sooty mangabey, and cynomolgus macaque.

Genetics[link]

Several genes have been associated with a susceptibility to leprosy.

Risk factors[link]

At highest risk are those living in endemic areas with poor conditions such as inadequate bedding, contaminated water, and insufficient diet, or other diseases that compromise immune function. However, though hard evidence is limited, and fringe publications have made passionate claims to the contrary, professional studies show little evidence that HIV is an important factor in increasing the risk of leprosy infection.^[37] It is presumed that this might be because of differences between the modes of immunity involved. However, it is plain that the two infections and their signs and progressions need not be fully independent, so the matter should be regarded with reserve.^[38][39] For example, a Medscape clinical presentation reports that HIV infection neither is a risk factor for acquisition nor for increased virulence of leprosy, but that latent cases of leprosy may emerge after starting HAART. Lewis, F. S. et al. ; Dermatologic Manifestations of Leprosy Clinical Presentation

Recent research suggests that there is a defect in cell-mediated immunity that causes susceptibility to Hansen's disease. Less than ten percent of the world's population is capable of acquiring the disease.^[40] The region of DNA responsible for this variability is also involved in Parkinson disease, giving rise to current speculation that the two disorders may be linked in some way at the biochemical level. In early 2003, an international team of scientists conducted a genome scan in Vietnamese multiplex leprosy families and found that susceptibility to leprosy was significantly linked to region q25 on the long arm of chromosome 6. Further confirmation of the chromosome 6 locus was provided by high-resolution linkage mapping in simplex leprosy families. Now, in a continuation of these findings, the team has pinpointed the chromosome 6 susceptibility locus to the 5' regulatory promoter region shared by both the Parkinson's disease gene PARK2 and its co-regulated gene PACRG.^[41] According to The Leprosy Mission Canada, most people-–about 95% of the population-–are naturally immune to the disease.^[40]

Pathophysiology[link]

The mechanism of transmission of leprosy is prolonged close contact and transmission by nasal droplet.^[13] In addition to humans, leprosy has been observed in nine-banded armadillo, (which, it has recently been confirmed, are among the primary sources of new cases of leprosy in Americans^[42]), and three species of primates.^[43] The bacterium can also be grown in the laboratory by injection into the footpads of mice.^[44] There is evidence that not all people who are infected with M. leprae develop leprosy, and genetic factors have long been thought to play a role, due to the observation of clustering of leprosy around certain families, and the failure to understand why certain individuals develop lepromatous leprosy while others develop other types of leprosy.^[45] It is estimated that due to genetic factors, only 5% of the population is susceptible to leprosy.^[46] This is mostly because the body is naturally immune to the bacteria, and those persons that do become infected experience severe allergic reactions to the disease. However, the role of genetic factors is not entirely clear in determining this clinical expression. In addition, malnutrition and prolonged exposure to infected persons may play a role in development of the overt disease.

The most widely held belief is that the disease is transmitted by contact between infected persons and healthy persons.^[47] In general, closeness of contact is related to the dose of infection, which in turn is related to the occurrence of disease. Of the various situations that promote close contact, contact within the household is the only one that is easily identified, although the incidence among contacts and the relative risk for them appear to vary considerably in different studies. In incidence studies, infection rates for contacts of lepromatous leprosy have varied from 6.2 per 1000 per year in Cebu, Philippines^[48] to 53 per 1000 per year in part of Western India to 55.8 per 1000 per year in a part of Southern India.^[49]

Two exit routes of M. leprae from the human body often described are the skin and the nasal mucosa, although their relative importance is not clear. Lepromatous cases show large numbers of organisms deep in the dermis, but whether they reach the skin surface in sufficient numbers is doubtful.^[26] Although there are reports of acid-fast bacilli being found in the desquamating epithelium (sloughing of superficial layer of skin) of the skin, Weddell et al. had reported in 1963 that they could not find any acid-fast bacilli in the epidermis, even after examining a very large number of specimens from patients and contacts.^[50] In a recent study, Job et al. found fairly large numbers of M. leprae in the superficial keratin layer of the skin of lepromatous leprosy patients, suggesting that the organism could exit along with the sebaceous secretions.^[51]

The importance of the nasal mucosa was recognized as early as 1898 by Schäffer, in particular that of the ulcerated mucosa.^[52] The quantity of bacilli from nasal mucosal lesions in lepromatous leprosy was demonstrated by Shepard as large, with counts ranging from 10,000 to 10,000,000.^[53] Pedley reported that the majority of lepromatous patients showed leprosy bacilli in their nasal secretions as collected through blowing the nose.^[54] Davey and Rees indicated that nasal secretions from lepromatous patients could yield as much as 10 million viable organisms per day.^[55]

The entry route of M. leprae into the human body is also not definitively known: The skin and the upper respiratory tract are most likely. While older research dealt with the skin route, recent research has increasingly favored the respiratory route. Rees and McDougall succeeded in the experimental transmission of leprosy through aerosols containing M. leprae in immune-suppressed mice, suggesting a similar possibility in humans.^[56] Successful results have also been reported on experiments with nude mice when M. leprae were introduced into the nasal cavity by topical application.^[57] In summary, entry through the respiratory route appears the most probable route, although other routes, particularly broken skin, cannot be ruled out. The CDC notes the following assertion about the transmission of the disease: "Although the mode of transmission of Hansen's disease remains uncertain, most investigators think that M. leprae is usually spread from person to person in respiratory droplets."^[58]

In leprosy, both the reference points for measuring the incubation period and the times of infection and onset of disease are difficult to define, the former because of the lack of adequate immunological tools and the latter because of the disease's slow onset. Even so, several investigators have attempted to measure the incubation period for leprosy. The minimum incubation period reported is as short as a few weeks and this is based on the very occasional occurrence of leprosy among young infants.^[59] The maximum incubation period reported is as long as 30 years, or over, as observed among war veterans known to have been exposed for short periods in endemic areas but otherwise living in non-endemic areas. It is generally agreed that the average incubation period is between three and five years.

Prevention[link]

In a recent trial, a single dose of rifampicin reduced the rate at which contacts acquired leprosy in the two years after contact by 57%; 265 treatments with rifampicin prevented one case of leprosy in this period.^[60] A non-randomized study found that rifampicin reduced the number of new cases of leprosy by 75% after three years.^[61]

BCG offers a variable amount of protection against leprosy as well as against tuberculosis.^[62][63]

Efforts to overcome persistent obstacles to the elimination of the disease include improving detection, educating patients and the population about its cause, and fighting social taboos about a disease that has caused its patients throughout history to be considered "unclean" or "cursed by God" as outcasts. Leprosy is not a hereditary disease. Where taboos are strong, patients may be forced to hide their condition (and avoid seeking treatment) to avoid discrimination. The lack of awareness about Hansen's disease can lead people to believe (falsely) that the disease is highly contagious and incurable.

The ALERT hospital and research facility in Ethiopia provides training to medical personnel from around the world in the treatment of leprosy, as well as treating many local patients. Surgical techniques, such as for the restoration of control of movement of thumbs, have been developed.

Treatment[link]

In 1988, Jacinto Convit was nominated for the Nobel Prize in Medicine, for developing a vaccine to fight leprosy, by combining a tuberculosis (TB) vaccines with Mycobacterium Leprae.

MDT anti-leprosy drugs: standard regimens

Enough synthetic pharmaceuticals that are effective against leprosy have by now been identified, and support a flexible choice of treatments. The WHO Study Group's report on the Chemotherapy of Leprosy in 1993 recommended two types of standard MDT regimen be adopted.^[64] The first was a 24-month treatment for multibacillary (MB or lepromatous) cases using rifampicin, clofazimine, and dapsone. The second was a six-month treatment for paucibacillary (PB or tuberculoid) cases, using rifampicin and dapsone. At the First International Conference on the Elimination of Leprosy as a Public Health Problem, held in Hanoi the next year, the global strategy was endorsed and funds provided to WHO for the procurement and supply of MDT to all endemic countries.

Between 1995 and 1999, WHO, with the aid of the Nippon Foundation (Chairman Yōhei Sasakawa, World Health Organization Goodwill Ambassador for Leprosy Elimination), supplied all endemic countries with free MDT in blister packs, channelled through Ministries of Health. This free provision was extended in 2000 and again in 2005 with donations by the MDT manufacturer Novartis through WHO. In the latest agreement signed between the company and WHO in October 2010, the provision of free MDT by WHO to all endemic countries will now run until at least the end of 2015. At the national level, non-government organizations (NGOs) affiliated to the national programme will continue to be provided with an appropriate free supply of this WHO supplied MDT by the government.

MDT remains highly effective, and patients are no longer infectious after the first monthly dose.^[13] It is safe and easy to use under field conditions due to its presentation in calendar blister packs.^[13] Relapse rates remain low, and there is no known resistance to the combined drugs.^[13] The Seventh WHO Expert Committee on Leprosy,^[65] reporting in 1997, concluded that the MB duration of treatment — then standing at 24 months — could safely be shortened to 12 months "without significantly compromising its efficacy."

Historical treatments[link]

This unreferenced section requires citations to ensure verifiability.

The disease was known in Ancient Greece as elephantiasis (elephantiasis graecorum). At various times blood was considered to be a treatment either as a beverage or as a bath.^{[citation needed]} That of virgins or children was considered to be especially potent.^{[citation needed]} This practice seems to have originated with the Ancient Egyptians but was also known in China. This practice persisted until at least 1790, when the use of dog blood was mentioned in De Secretis Naturae. Paracelsus recommended the use of lamb's blood and even blood from dead bodies was used.

Snakes were also used, according to Pliny, Aretaeus of Cappadocia, and Theodorus. Gaucher recommended treatment with cobra venom. Boinet, in 1913, tried increasing doses of bee stings (up to 4000). Scorpions and frogs were used occasionally instead of snakes. The excreta of Anabas (the climbing fish) was also tried.

Alternative treatments included scarification with or without the addition of irritants including arsenic and hellebore. Castration was also practiced in the Middle Ages.

Chaulmoogra oil

A common pre-modern treatment of leprosy was chaulmoogra oil.

The oil has long been used in India as an Ayurvedic medicine for the treatment of leprosy and various skin conditions. It has also been used in China and Burma, and was introduced to the West by Frederic John Mouat, a professor at Bengal Medical College. He tried the oil as an oral and topical agent in two cases of leprosy and reported significant improvements in an 1854 paper.^[66]

This paper caused some confusion. Mouat indicated that the oil was the product of a tree Chaulmoogra odorata, which had been described in 1815 by William Roxburgh, a surgeon and naturalist, while he was cataloging the plants in the East India Company’s botanical garden in Calcutta. This tree is also known as Gynocardia odorata. For the rest of the 19th century, this tree was thought to be the source of the oil. In 1901, Sir David Prain identified the true chaulmoogra seeds of the Calcutta bazaar and of the Paris and London apothecaries as coming from Taraktogenos kurzii, which is found in Burma and Northeast India. The oil mentioned in the Ayurvedic texts was from the tree Hydnocarpus wightiana, known as Tuvakara in Sanskrit and chaulmugra in Hindi and Persian.

The first parenteral administration was given by the Egyptian doctor Tortoulis Bey, personal physician to the Sultan Hussein Kamel of Egypt. He had been using subcutaneous injections of creosote for tuberculosis and in 1894 administered subcutaneous injection of chaulmoogra oil in a 36-year-old Egyptian Copt who had been unable to tolerate oral treatment. After 6 years and 584 injections, the patient was declared cured.

An early scientific analysis of the oil was carried out by Frederick B. Power in London in 1904. He and his colleagues isolated a new unsaturated fatty acid from the seeds, which they named 'chaulmoogric acid'. They also investigated two closely related species: Hydnocarpus anthelmintica and Hydnocarpus wightiana. From these two trees they isolated both chaulmoogric acid and a closely related compound, 'hydnocarpus acid'. They also investigated Gynocardia odorata and found that it produced neither of these acids. Later investigation showed that 'taraktogenos' (Hydnocarpus kurzii) also produced chaulmoogric acid.

Another difficulty with the use of this oil was administration. Taken orally it is extremely nauseating. Given by enema may cause peri-anal ulcers and fissures. Given by injection the drug caused fever and other local reactions. Despite these difficulties, a series of 170 patients were reported in 1916 by Ralph Hopkins, the attending physician at the Louisiana Leper Home in Carville, Louisiana. He divided the patients into two groups - 'incipient' and 'advanced'. In the advanced cases, 25% (at most) showed any improvement or arrest of their condition; in the incipient cases, 45% reported an improvement or stabilization of the disease (mortality rates were 4% and 8%, respectively). The remainder absconded from the Home apparently in improved condition.

Given the apparent usefulness of this agent, a search began for improved formulations. Victor Heiser the Chief Quarantine Officer and Director of Health for Manila and Elidoro Mercado the house physician at the San Lazaro Hospital for lepers in Manila decided to add camphor to a prescription of chaulmoogra and resorcin, which was typically given orally at the suggestion of Merck and Company in Germany to whom Heiser had written. They found that this new compound was readily absorbed without the nausea that had plagued the earlier preparations.

Heiser and Mercado in 1913 then administered the oil by injection to two patients who were cured of the disease. Since this treatment was administered in conjunction with other materials, the results were not clear. A further two patients were treated with the oil by injection without other treatments and again appeared to be cured of the disease. The following year, Heiser reported a further 12 patients but the results were mixed.

Less toxic injectable forms of this oil were then sought. Between 1920 and 1922, a series of papers were published describing the esters of these oils. These may have been based on the work of Alice Ball—the record is not clear on this point and Ms Ball died in 1916. Trials of these esters were carried out in 1921 and appeared to give useful results.

These attempts had been preceded by others. Merck of Darmstadt had produced a version of the sodium salts in 1891. They named this sodium gynocardate in the mistaken belief that the origin of the oil was Gynocardia odorata. Bayer in 1908 marketed a commercial version of the esters under the name 'Antileprol'.

To ensure a supply of this agent Joseph Rock, Professor of Systematic Botany at the College of Hawaii, traveled to Burma. The local villagers located a grove of trees in seed, which he used to establish a plantation of 2,980 trees on the island of Oahu, Hawaii between 1921 and 1922.

The oil remained a popular treatment despite the common side effects until the introduction of sulfones in the 1940s. Debate about its efficacy continued until it was discontinued.

Modern drug treatment

MDT patient packs and blisters

It has been said that Promin was first synthesised in 1940 by Feldman of Parke-Davis and company.^[67] Although Parke-Davis did in fact synthesise the compound, it seems certain that they were not the first; in cooperation with J. Wittmann, Emil Fromm synthesised both dapsone and some of its derivatives, including promin, in 1908. He was however a chemist and not a medical worker, nor did anyone investigate its medical value until some decades afterwards.^[68]

Until the introduction of treatment with promin in the 1940s, there was no effective treatment for leprosy. The efficacy of promin was first discovered by Guy Henry Faget and his co-workers in 1943 at Carville, Louisiana. In the 1950s dapsone was introduced to Carville by Dr. R.G. Cochrane. It is only weakly bactericidal against M. leprae and it was considered necessary for patients to take the drug indefinitely. When dapsone was used alone, the M. leprae population quickly evolved antibiotic resistance; by the 1960s, the world's only known anti-leprosy drug became virtually useless.

The search for more effective anti-leprosy drugs led to the use of clofazimine and rifampicin in the 1960s and 1970s.^[69] Later, Indian scientist Shantaram Yawalkar and his colleagues formulated a combined therapy using rifampicin and dapsone, intended to mitigate bacterial resistance.^[70] The first trials of combined treatment were carried out in Malta in the 1970s.

Multidrug therapy (MDT) combining all three drugs was first recommended by a WHO Expert Committee in 1981. These three anti-leprosy drugs are still used in the standard MDT regimens. None of them is used alone because of the risk of developing resistance.

This treatment was quite expensive, and was not quickly adopted in most endemic countries. In 1985, leprosy was still considered a public health problem in 122 countries. The 44th World Health Assembly (WHA), held in Geneva in 1991, passed a resolution to eliminate leprosy as a public-health problem by the year 2000 — defined as reducing the global prevalence of the disease to less than 1 case per 10,000. At the Assembly, the World Health Organization (WHO) was given the mandate to develop an elimination strategy by its member states, based on increasing the geographical coverage of MDT and patients’ accessibility to the treatment.

Worldwide, two to three million people are estimated to be permanently disabled because of leprosy.^[14] India has the greatest number of cases, with Brazil second and Myanmar third.

In 1999, the world incidence of Hansen's disease was estimated to be 640,000. In 2000, 738,284 cases were identified.^[72] In 2000, the World Health Organization (WHO) listed 91 countries in which Hansen's disease is endemic. India, Burma, and Nepal contained 70% of cases. India reports over 50% of the world's leprosy cases.^[73] In 2002, 763,917 new cases were detected worldwide, and in that year the WHO listed Brazil, Madagascar, Mozambique, Tanzania, and Nepal as having 90% of Hansen's disease cases.

According to recent figures from the WHO, new cases detected worldwide have decreased by approximately 107,000 cases (or 21%) from 2003 to 2004. This decreasing trend has been consistent for the past three years. In addition, the global registered prevalence of HD was 286,063 cases; 407,791 new cases were detected during 2004.

In the United States, the first definite reference to the disease was in Florida in 1758. In 2004, there were 131 total cases of the disease in the United States. Of the 131 cases, two-thirds were found to be males. Also out of the 131 cases, 25 were of individuals who were born in the country, which amounts to 19%. Mexico (18.3%), Micronesia (11.5%), Brazil (9.2%), and the Philippines (7.6%) were the next leading countries where the victims of the disease were originally born. A total of 20 cases were found to be white, not of Hispanic origin. As of October, 2005, 3,604 patients on the United States registry were currently receiving care.^[74] The disease is tracked by the Centers for Disease Control and Prevention (CDC), with a total of 166 new cases reported in the U.S. in 2005. Most (100 or 60%) of these new cases were reported in the following states; California, Louisiana, Massachusetts, New York, and Texas.^[34] Although the number of cases worldwide continues to fall, pockets of high prevalence continue in certain areas such as Brazil, South Asia (India, Nepal), some parts of Africa (Tanzania, Madagascar, Mozambique), and the western Pacific.

Disease burden[link]

Although annual incidence — the number of new leprosy cases occurring each year — is important as a measure of transmission, it is difficult to measure in leprosy due to its long incubation period, delays in diagnosis after onset of the disease, and the lack of laboratory tools to detect leprosy in its very early stages. Instead, the registered prevalence is used. Registered prevalence is a useful proxy indicator of the disease burden, as it reflects the number of active leprosy cases diagnosed with the disease and receiving treatment with MDT at a given point in time. The prevalence rate is defined as the number of cases registered for MDT treatment among the population in which the cases have occurred, again at a given point in time.^[75]

New case detection is another indicator of the disease that is usually reported by countries on an annual basis. It includes cases diagnosed with onset of disease in the year in question (true incidence) and a large proportion of cases with onset in previous years (termed a backlog prevalence of undetected cases).

Endemic countries also report the number of new cases with established disabilities at the time of detection, as an indicator of the backlog prevalence. Determination of the time of onset of the disease is, in general, unreliable, is very labor-intensive, and is seldom done in recording these statistics.

As reported to WHO by 115 countries and territories in 2006, and published in the Weekly Epidemiological Record, the global registered prevalence of leprosy at the beginning of the year was 219,826 cases.^[76] New-case detection during the previous year (2005 - the last year for which full country information is available) was 296,499. The reason for the annual detections being higher than the prevalence at the end of the year can be explained by the fact that a proportion of new cases complete their treatment within the year and, therefore, no longer remain on the registers. The global detection of new cases continues to show a sharp decline, falling by 110,000 cases (27%) during 2005 compared with the previous year.

Table 1 shows that global annual detection has been declining since 2001. The African region reported an 8.7% decline in the number of new cases compared with 2004. The comparable figure for the Americas was 20.1%, for South-East Asia 32%, and for the Eastern Mediterranean 7.6%. The Western Pacific area, however, showed a 14.8% increase during the same period.

Table 2 shows the leprosy situation in the four major countries that have yet to achieve the goal of elimination at the national level. It should be noted that: a) Elimination is defined as a prevalence of less than 1 case per 10,000 population; b) Madagascar reached elimination at the national level in September 2006; c) Nepal detection reported from mid-November 2004 to mid-November 2005; and d) D.R. Congo officially reported to WHO in 2008 that it had reached elimination by the end of 2007, at the national level.

History[link]

G. H. A. Hansen, discoverer of M. leprae

DNA taken from the shrouded remains of a man discovered in a tomb next to the Old City of Jerusalem shows him to be the earliest human proven to have suffered from leprosy. The remains were dated by radiocarbon methods to 1-50 A.D.^[77]

After the end of the 17th century, Norway, Iceland and England were the countries in Western Europe where leprosy was a significant problem. During the 1830s, the number of lepers in Norway, Iceland and England rose rapidly, believed to be caused by frequent visits of sailors who visited Western India, causing an increase in medical research into the condition, and the disease became a political issue. Norway appointed a medical superintendent for leprosy in 1854 and established a national register for lepers in 1856, the first national patient register in the world.^[78]

Mycobacterium leprae, the causative agent of leprosy, was discovered by G. H. Armauer Hansen in Norway in 1873, making it the first bacterium to be identified as causing disease in humans.^[79][80] The principal opposition to Hansen's view that leprosy was an infectious disease came from his father-in-law, Daniel Cornelius Danielssen who considered it a hereditary disease and had stated this in his book, ‘’Traité de la Spedalskhed ou Elephantiasis des Grecs’’ - the standard reference book on leprosy from 1848 until the death of Danielssen in 1895.^[81]

Hansen observed a number of nonrefractile small rods in unstained tissue sections. The rods were not soluble in potassium lye, and they were acid- and alcohol-fast. In 1879, he was able to stain these organisms with Ziehl's method and the similarities with Koch's bacillus (Mycobacterium tuberculosis) were noted. There were three significant differences between these organisms: (1) the rods in the leprosy lesions were extremely numerous, (2) they formed characteristic intracellular collections (globii), and (3) the rods had a variety of shapes with branching and swelling. These differences suggested that leprosy was caused by an organism related to but distinct from Mycobacterium tuberculosis.

He worked at St. Jørgens Hospital in Bergen, founded early in the fifteenth century. St. Jørgens is today a museum, Lepramuseet, it can be argued the best-preserved leprosy hospital in Northern Europe.^[82]

Etymology[link]

The word leprosy comes from ancient Greek Λέπρα [léprā], "a disease that makes the skin scaly", in turn, a nominal derivation of the verb Λέπω [lépō], "to peel, scale off". Λέπος (Lepos) in ancient Greek means peel, or scale, so from Λέπος we have Λεπερός (Λεπερός = who has peels - scales) --> and then Λεπρός (=leprous).^[83] The word came into the English language via Latin and old French. The first attested English use is in the Ancrene Wisse, a 13th-century manual for nuns ("Moyseses hond..bisemde o þe spitel uuel & þuhte lepruse." The Middle English Dictionary, s.v., "leprous"). A roughly contemporaneous use is attested in the Anglo-Norman Dialogues of Saint Gregory, "Esmondez i sont li lieprous" (Anglo-Norman Dictionary, s.v., "leprus").

Throughout history, individuals with Hansen's disease have been known as lepers; however, this term is falling into disuse as a result of the diminishing number of leprosy patients. Because of the stigma to patients, some prefer not to use the word "leprosy," though the term is used by the U.S. Centers for Disease Control and Prevention and the World Health Organization.^[26] Historically, the term Tzaraath from the Hebrew Bible was, erroneously, commonly translated as leprosy, although the symptoms of Tzaraath were not entirely consistent with leprosy and, rather, referred to a variety of disorders other than Hansen's disease.^[84] The first mention of leprosy recorded is found in Leviticus 13:2 - "When a man shall have in the skin of his flesh a rising, a scab, or bright spot, and it be in the skin of his flesh like the plague of leprosy; then he shall be brought unto Aaron the priest, or unto one of his sons the priests." There is also the well-known Bible story of the Syrian Naaman, "captain of the host of the king of Syria" (2 Kings 5:1), who suffered from this severe and savage skin disease.

In particular, tinea capitis (fungal scalp infection) and related infections on other body parts caused by the dermatophyte fungus Trichophyton violaceum are abundant throughout the Middle East and North Africa today and might also have been common in biblical times. Likewise, the related agent of the disfiguring skin disease favus Trichophyton schoenleinii appears to have been common throughout Eurasia and Africa before the advent of modern medicine. Persons with severe favus and similar fungal diseases (and potentially also with severe psoriasis and other diseases not caused by microorganisms) tended to be classed as having leprosy as late as the 17th century in Europe.^[85] This is clearly shown in the painting The Regents of the Leper Hospital in Haarlem 1667 by Jan de Bray (Frans Hals Museum, Haarlem, the Netherlands), where a young Dutchman with a vivid scalp infection, it is presumed caused by a fungus, is shown being cared for by three officials of a charitable home intended for leprosy sufferers.^{[citation needed]} The use of the word "leprosy" before the mid-19th century, when microscopic examination of skin for medical diagnosis was first developed, can seldom be correlated reliably with Hansen's disease as we understand it today.^{[citation needed]}

Ancient Rome[link]

In the West, the earliest known description of leprosy there was made by the Roman encyclopedist Aulus Cornelius Celsus (25 BC – 37 AD) in his De Medicina; he called leprosy "elephantiasis".^[86] The Roman author Pliny the Elder (23–79 AD) mentioned the same disease.^[86] Although "sara't" of Leviticus (Old Testament) is translated as "lepra" in the 5th century AD Vulgate, the original term sara't found in Leviticus was not the elephantiasis described by Celsus and Pliny; in fact, sara't was used to describe a disease that could affect houses and clothing.^[86] Katrina C. D. McLeod and Robin D. S. Yates state that sara't "denotes a condition of ritual impurity or a temporary form of skin disease."^[86]

Iran[link]

The Persian polymath Avicenna (c. 980–1037) was the first outside of China to describe the destruction of the nasal septum in those suffering from leprosy.^[86]

Middle Ages[link]

Numerous leprosaria, or leper hospitals, sprang up in the Middle Ages; Matthew Paris, a Benedictine Monk, estimated that in the early thirteenth century there were 19,000 across Europe.^[87] The first recorded Leper colony was in Harbledown, England. These institutions were run along monastic lines and, while lepers were encouraged to live in these monastic-type establishments, this was for their own health as well as quarantine. Indeed, some medieval sources indicate belief that those suffering from leprosy were considered to be going through Purgatory on Earth, and for this reason their suffering was considered holier than the ordinary person's. More frequently, lepers were seen to exist in a place between life and death: They were still alive, yet many chose or were forced to ritually separate themselves from mundane existence.^[88] The Order of Saint Lazarus was a hospitaller and military order of monks that began as a leper hospital outside Jerusalem in the twelfth century and remained associated with leprosy throughout its history. The first monks in this order were leper knights, and they originally had leper grand masters, although these aspects of the order changed over the centuries.

Radegund was noted for washing the feet of lepers. Orderic Vitalis writes of a monk, Ralf, who was so overcome by the plight of lepers that he prayed to catch leprosy himself (which he eventually did). The leper would carry a clapper and bell to warn of his approach, and this was as much to attract attention for charity as to warn people that a diseased person was near.

India[link]

The Oxford Illustrated Companion to Medicine holds that the mention of leprosy, as well as cures for it, were already described in the Hindu religious book Atharva-veda.^[89] Writing in the Encyclopædia Britannica 2008, Kearns & Nash state that the first mention of leprosy is in the Indian medical treatise Sushruta Samhita (6th century BC).^[90] The Cambridge Encyclopedia of Human Paleopathology (1998) holds that: "The Sushruta Samhita from India describes the condition quite well and even offers therapeutic suggestions as early as about 600 BC"^[91] The surgeon Sushruta lived in the Indian city of Kashi by the 6th century BC,^[92] and the medical treatise Sushruta Samhita — attributed to him — made its appearance during the 1st millennium BC.^[90] The earliest surviving excavated written material that contains the works of Sushruta is the Bower Manuscript—dated to the 4th century AD, almost a millennium after the original work.^[93] Despite the existence of these earlier works the first generally considered accurate description of the disease was that of Galen of Pergamum in 150 AD.

In 2009, a 4,000-year-old skeleton was uncovered in India that was shown to contain traces of leprosy.^[94] The discovery was made at a site called Balathal, which is today part of Rajasthan, and is believed to be the oldest case of the disease ever found.^[95] This pre-dated the previous earliest recognized case, dating back to 6th-century Egypt, by 1,500 years.^[96] It is believed that the excavated skeleton belonged to a male, who was in his late 30s and belonged to the Ahar Chalcolithic culture.^[96][97] Archaeologists have stated that not only does the skeleton represent the oldest case of leprosy ever found, but is also the first such example that dates back to prehistoric India.^[98] This finding supports one of the theories regarding the origin of the disease, which is believed to have originated in either India or Africa, before being subsequently spread to Europe by the armies of Alexander the Great.^[95]

In 1874, the Missions to Lepers Act was brought about as a means to treat leprosy by segregating males and females in the institutions.^[99] The asylum superintendents believe that this separation was beneficial because no children were to be born into families of diseased parents, the act of which was considered a sin. Leprosy at this time was still believed to be hereditarily transmitted from parents to offspring though the bacteria causing leprosy was discovered by Dr. Gerhard Armauer Hansen just one year before ^[100]

In 1881, around 120,000 leprosy patients existed in India. The central government passed the Lepers Act of 1898, which provided legal provision for forcible confinement of leprosy sufferers in India.^[101]

China[link]

Regarding ancient China, Katrina C. D. McLeod and Robin D. S. Yates identify the State of Qin's Feng zhen shi 封診式 (Models for sealing and investigating), dated 266-246 BC, as offering the earliest known unambiguous description of the symptoms of low-resistance leprosy, even though it was termed then under li 癘, a general Chinese word for skin disorder.^[86] This 3rd-century BC Chinese text on bamboo slip, found in an excavation of 1975 at Shuihudi, Yunmeng, Hubei province, described not only the destruction of the "pillar of the nose" but also the "swelling of the eyebrows, loss of hair, absorption of nasal cartilage, affliction of knees and elbows, difficult and hoarse respiration, as well as anesthesia."^[86]

Indonesia[link]

Across Indonesia the rate of prevalence is slightly under one new case per 10,000 people, with approximately 20,000 new cases detected each year.^[102] However, the rate is considerably higher in particular regions, particularly South Sulawesi (with more than 3 new cases per 10,000 people) and North Maluku (with more than 5 new cases per ten thousand people).^[102] MDT is provided free of charge to patients who require it in Indonesia and there are a number of hospitals in major population centers specifically intended to deal with the medical needs of those affected by the disease.^[102] While the early detection and treatment of leprosy has certainly improved over the years, approximately ten percent of patients in Indonesia have already suffered significant nerve or other damage prior to the identification and treatment of their disease, largely due to lack of awareness and to a pervasive stigma that discourages those with the disease from coming forward to seek treatment.^[102]

PERMATA (Perhimpunan Mandiri Kusta) Indonesia was established in 2007 with the specific vision of fighting the stigma associated with leprosy and eliminating the discrimination against those identified as suffering from the disease. The organization was founded by a small group of individuals who had all personally been treated for leprosy. The founders worked to establish links with key figures amongst those suffering from the disease in communities in South Sulawesi, East Java and NTT, the three provinces where the rate of incidence of the disease is probably amongst the highest in Indonesia.^[103]

Japan[link]

Japan has had a unique history of segregation of patients into sanatoriums based on leprosy prevention laws of 1907, 1931, and 1953, and, hence, it intensified leprosy stigma. The 1953 law was abrogated in 1996. There are still 2717 ex-patients in 13 national sanatoriums and 2 private hospitals as of 2008. In a document written in 833, leprosy was described as "caused by a parasite that eats five organs of the body. The eyebrows and eyelashes come off, and the nose is deformed. The disease brings hoarseness, and necessitates amputations of the fingers and toes. Do not sleep with the patients, as the disease is transmittable to those nearby." This was the first document concerning infectivity.^[104] Males admitted to leprosariums in Japan were sterilized and females found to be pregnant were forced to have abortions. These extreme actions were done to prevent children of diseased parents from being born lest they also contract the disease. Doctors during this time still mistakenly believed that leprosy was a hereditary disease.^[105] Lepers were seen as being incurable and infectious, the main reason they were forced into exile.

Society and culture[link]

Stigma in India[link]

Leprosy patients in India, like many parts of world, suffer under some of the worst conditions and stereotypes about their disease. Depending on the level of disfigurement a leper could receive harsher stigma and ostracism. Leprosy sufferers are markedly disadvantaged with respect to income with 16-44% of victims reporting a decrease in pay as a result of having leprosy. Women suffer greater restrictions and social stigma than men. Leprosy prevents mothers from getting too close to their children out of fear that they could infect them. In a report, 49% of women stopped breast-feeding their babies as a result of having leprosy. Doctors and other health care providers and NGOs are working hard to educate people about the disease. In one study when leprosy treatment and education were mixed in with the local healthcare program the attitudes towards the disease were somewhat alleviated as people had a better understanding of it.Now the disease prevalence has been reduced to less than 1 per million population in most parts of the country. ^[106]

Notable cases[link]

• Saint Damien DeVeuster, a Roman Catholic priest from Belgium who ministered to the people with leprosy who had been placed under a government-sanctioned medical quarantine on the island of Molokaʻi in the Kingdom of Hawaiʻi.^[107]
• Baldwin IV, who was a king of Latin Jerusalem and was portrayed as a character in the film Kingdom of Heaven^[108]
• Vietnamese poet Han Mac Tu^[109]
• Ōtani Yoshitsugu, a Japanese daimyo^[110]
• Biblical writings have a number of references such as Moses' sister, Miriam,^[111] Moses,^[112] commander of the army of Syria Naaman the Syrian and later the prophet Elisha's servant Gehazi,^[113] and several people Jesus healed,^{[114][115][116]} though the afflicted mentioned and symptoms described are now thought not to be, or not exclusively to be, the result of Hansen's Disease (see discussion at 'Tzaraath').

Louis Carl "Lou" Dobbs^[1] (born September 24, 1945) is an American journalist, radio host, television host on the Fox Business Network, and author. He anchored CNN's Lou Dobbs Tonight until November 2009 when he announced on the air that he would leave the 24-hour cable news television network.^[2][3]

He was born in Texas and lived there and in Idaho during his childhood. After graduating from Harvard University, Dobbs worked in government and banking before becoming a news reporter for several local media outlets. He had worked with CNN since its founding in 1980, serving as a reporter and vice president. He was the host and managing editor for CNN's Moneyline, which premiered in 1980 and was renamed Lou Dobbs Tonight in 2003. Dobbs resigned from CNN in 1999, rejoined in 2000, and resigned again in November 2009. He also hosts a syndicated radio show, Lou Dobbs Radio and has written several books since 2001.

Dobbs describes himself as an "independent populist" and is known for his opposition to NAFTA and support for immigration enforcement. For his reporting, he has won Emmy, Peabody, and Cable ACE awards.

After Dobbs left CNN in 2009, he gave an interview where he did not rule out the possibility of running for President of the United States in 2012, saying the final decision would rest with his wife, although former Senator Dean Barkley has encouraged Dobbs to run.^[4][5][6] Dobbs also acknowledged, via a spokesperson, that he is also considering a run for the United States Senate in New Jersey in 2012.^[7]

Background and family life[link]

Born in Childress County, Texas, Dobbs is the son of Frank Dobbs, a co-owner of a propane business, and Lydia Mae (née Hensley), a bookkeeper.^[1] When Dobbs was 12, his father's propane business failed and the family moved to Rupert, Idaho.^[8] He attended Minico High School in Minidoka County, where he played tackle on the football team and served as student body president and played the souzaphone in the band.^[9] Although accepted at the University of Idaho and Idaho State University, he was persuaded by the staff at Minico High to apply to Harvard University, where he was accepted and later graduated from with a Bachelor of Arts degree in economics in 1967.^[9]

After graduating, Dobbs worked for federal anti-poverty programs in Boston and Washington, D.C. He briefly attended law school at the University of Idaho in Moscow, then worked as a cash-management specialist for Union Bank in Los Angeles. He married his high school sweetheart in 1969, and in 1970 their first son was born. Dobbs moved to Yuma, Arizona and got a job as a police and fire reporter for KBLU-AM. By the mid-1970s he was a television anchor and reporter in Phoenix, and he later joined Seattle's KING-TV. In 1979, he was contacted by a recruiter for Ted Turner, who was in the process of forming CNN.^[8] He is married to his second wife, Debi Lee Segura, a Mexican-American who was, at one time, a CNN sports anchor. The couple has had four children together.^[10] Dobbs resides on a 300-acre (1.2 km²) horse farm in Sussex County, New Jersey.^[10]

Career[link]

CNN[link]

Dobbs joined CNN when it launched in 1980, serving as its chief economics correspondent and as host of the business news program Moneyline on CNN. Dobbs also served as a corporate executive for CNN, as its executive vice president and as a member of CNN's executive committee. He founded CNN fn (CNN financial news), serving as its president and anchoring the program Business Unusual, which examined business creativity and leadership.^[11]

Departure and founding of Space.com[link]

Dobbs repeatedly clashed with Rick Kaplan, who became president of CNN in 1997. Dobbs said Kaplan, noted friend of then president Bill Clinton, was "clearly partisan" and "was pushing Clinton stories," while Kaplan said Dobbs was "a very difficult person to work with."^[8]

On April 20, 1999, CNN was covering Clinton's speech in Littleton, Colorado, following the Columbine High School massacre. Dobbs ordered the producer to cut away from the speech and return to broadcast Moneyline.^[8] Dobbs was countermanded by Kaplan, who ordered CNN to return to the speech. Kaplan later said, "Tell me what journalistic reason there was not to cover the president at Columbine soon after the shootings? Everyone else was doing it." Dobbs announced on the air that "CNN President Rick Kaplan wants us to return to Littleton." A few days later, Dobbs announced that he was leaving the network to start Space.com, a website devoted to astronautical news.^[8] Dobbs was subsequently replaced as host of Moneyline by Willow Bay and Stuart Varney.^[12]

Return to CNN[link]

Kaplan left CNN in August 2000, and Dobbs returned the following year, at the behest of his friend and CNN founder Ted Turner, becoming host and managing editor of the new and initially more general news program Lou Dobbs Reporting, which later became CNN News Sunday Morning. He also regained the helm of the newly renamed Lou Dobbs Moneyline (which became Lou Dobbs Tonight in June 2003).^[13]

Radio[link]

From 2009 to 2012, Dobbs hosted Lou Dobbs Radio on United Stations Radio Networks. The three hour daily show had affiliates in several major markets, including its flagship station (WOR) in New York City, Washington D.C. (WHFS), Miami (WZAB-AM) and the San Francisco Bay Area (KDOW), as well as stations such as WGNY-AM in Newburgh, New York. The show was guest-centered and featured political discussion and listener calls. It aired from 2 to 5 p.m. Eastern, directly competing with The Sean Hannity Show and The Dave Ramsey Show. Dobbs also hosts the financially themed Lou Dobbs Minute on the same network.

In June 2008, Dobbs reached an agreement with Business TalkRadio Network to carry a rebroadcast of the show from 7 p.m. to 10 p.m. Eastern, displacing Bruce Williams. Dobbs's show is also carried live on CRN Digital Talk Radio Networks, on CRN4.

Dobbs was among the hosts who tried out for the position vacated by the cancellation of Imus in the Morning on WFAN, a position that was eventually filled by Boomer and Carton in the Morning. Dobbs mentioned on his radio show that he is currently seeking a position in the US Department of Treasury during the economic crisis. He stated that he believed he could "do more good than the clowns currently in position."

Dobbs also is a regular columnist in Money magazine, U.S. News & World Report, and the New York Daily News.^[8]

Exit from CNN[link]

On the November 11, 2009 edition of his nightly broadcast Lou Dobbs Tonight, Dobbs announced his immediate departure from CNN, ending a nearly thirty year career at the network, citing plans to "pursue new opportunities."^[2][3] CNN President Jon Klein said that Dobbs' departure was not a result of organized opposition to Dobbs' viewpoints.^[14][15] His departure came less than two weeks after an incident in which a shot was fired at his home.^[16]

In July 2009, controversy around Dobbs began when he was the only mainstream news anchor to give airtime to the birther conspiracy theory.^[17] Several liberal advocacy groups, including Media Matters, and the Southern Poverty Law Center criticized Dobbs for his reporting. The controversy eventually caused CNN President Jon Klein to rein Dobbs in via an internal memorandum.^[18] In September, advocates challenged Dobbs for appearing at a FAIR conference (Federation for American Immigration Reform), a leading anti-illegal immigration group. Multiple campaigns were launched, including Drop Dobbs (NDN, Media Matters), and Basta Dobbs (Presente.org).^[19]

The campaigns also attacked CNN for alleged hypocrisy towards Latinos, citing CNN's "Latino in America" special as incompatible with their continued support of Dobbs. The campaigns generated considerable anti-Dobbs press,^[20] and are credited by some^[who?] as pushing Dobbs out.

Dobbs was reportedly paid $8 million in severance pay when he left CNN prior to his contract being due for renewal.^[21]

Since his resignation from CNN, Dobbs has made regular appearances to discuss issues on other news network programs including CNBC's The Kudlow Report and Fox News Channel's The O'Reilly Factor. Dobbs continues to broadcast his American radio show and publish his syndicated column.

Current show on Fox Business Network[link]

On November 10, 2010, Fox Business Network announced that Dobbs will host a show on the channel.^[22] The network announced on March 3, 2011 the start date, show title, and time slot of Dobbs' new show. The show is titled Lou Dobbs Tonight and began on March 14, 2011, airing at 7 PM Eastern. That is the same title and time slot that Dobbs' old CNN show had.^[23]

Cameo appearances[link]

On October 5, 2010, Dobbs made a guest appearance on an episode of The Good Wife, entitled "Double Jeopardy",^[24] in which he plays himself as a client in search of a new law firm to represent his legal interests.

Political views[link]

In his early career Dobbs was known as a fiscal conservative. He is a critic of the "excesses of capitalism," which he identifies as globalization, offshore outsourcing, runaway film production (the outsourcing of Hollywood jobs),^[25][26] illegal immigration, free trade deals, corporate/big business influence in government and the Bush administration's tax cuts. He describes himself as an advocate of economic populism, warning that outsourcing and the U.S. trade and budget deficits threaten the American middle class. Dobbs tends to oppose long-run trade deficits and outsourcing for the sake of labor arbitrage to obtain cheap labor.

In the 2000s, Dobbs has used CNN programs and columns to express his personal views on several subjects. He has become particularly noted for two positions: Dobbs is a critic of American immigration policy and expanded international trade. He is particularly wary of outsourcing and off-shoring, especially with China.^[27] He was a known political figure in New Jersey, with a Fairleigh Dickinson University PublicMind poll finding that he had a 70% name recognition among New Jersey voters in January 2010. Among these voters, 22% had a favorable view of Dobbs while 22% had an unfavorable view.^[28]

Illegal immigration and border security[link]

Dobbs has been strongly opposed to both illegal immigration and such labor-outsourcing and foreign worker programs as the H-1B visa program and guest-worker programs.^[29][30] He has been a critic of the Mexican government's poverty programs, and of church leaders in Mexico for not criticizing the Mexican government's policies on border security and illegal immigration.

Lou Dobbs Tonight frequently featured themes of "Exporting America," "Broken Borders," and "War on the Middle Class". The newscast often described illegal immigration as an "invasion." Dobbs dismissed concerns about his rhetoric as "political correctness" in the segment billboarded "P.C. Nation".

In his "Broken Borders" segments, Dobbs focused primarily on the southern border with Mexico and the drugs and the people who cross it. Dobbs has lauded the Canadian government for cooperation in securing the border with their American counterparts.

In an interview with Lesley Stahl, Dobbs spoke about his meeting with the Congressional Hispanic Caucus, saying they implied that he was anti-Hispanic by asking him, "if [he had] ever eaten a taco before, for God's sake".^[31] Representative Joe Baca, chairman of the Congressional Hispanic Caucus, later wrote to CBS insisting that the group did not meet with Dobbs to discuss whether he'd eaten Hispanic food, "but to respectfully recommend that he cease the negative portrayal of Hispanics...and treat the issue of immigration in a responsible manner."^[32]

Some of the reporting on the show has been criticized including a claim that illegal aliens were responsible for bringing 7,000 new cases of leprosy to the United States in a three year period, but the actual timeframe was over the last thirty years, according to James L. Krahenbuhl, the director of the National Hansen’s Disease Program.^[33]

Dobbs has criticized local officials for their approach to border security. In October 2007 he labeled then New York Governor Eliot Spitzer an "idiot" for advocating the issuance of driver's licenses to illegal immigrants.^[34] Hillary Clinton labeled Dobbs' illegal immigration segments as having "all that hot air."^[35][36]

At about 10:30 a.m. on October 5, 2009, a bullet struck Dobbs's home as Dobbs and his wife stood outside it. ^[37] The bullet struck the vinyl siding of their attic without penetrating the vinyl and fell to the ground.^[38] Dobbs attributed the incident to his stance against amnesty for illegal immigrants.^[39] The New Jersey State Troopers' account of the incident attributed to a stray bullet from a hunter in the vicinity.^[38]

In December 2009, Dobbs stated in an interview with Telemundo that he now supports a plan to legalize undocumented workers.^[40]
