Dengue…
It’s prevention -
Dengue fever is a disease caused by viruses that are transmitted to people by mosquitoes.
Dengue (pronounced as Den-gay) is an acute febrile illness lasting from 2 to
7 days. The fever comes with headache, retro orbital puffiness, myalgias rash and may have two peaks.
Dengue fever usually causes fever (high, about 104
F-105 F), skin rash and pain (headaches and often severe muscle and joint pains). The disease has also been termed "break bone fever" or "dandy fever" because the unusually severe muscle and joint pains can make people assume distorted body positions or exaggerated walking movements in an effort to reduce their pain.
The viruses are transmitted from
Aedes aegypti and
Aedes albopictus mosquitoes to humans in a viral life cycle that requires both humans and these mosquitoes. There is no human-to-human dengue fever transmission.
Once a mosquito is infected, it remains infected for its life span
This female mosquito normally bites at dusk and dawn.
Researchers suggest the surge in dengue fever may be due to several factors:
• Increased urban crowding with more sites for mosquitoes to develop.
Researchers suggest the surge in dengue fever may be due to several factors:
•
International commerce that contains infected mosquitoes, thus introducing the disease to areas previously free of the disease.
Researchers suggest the surge in dengue fever may be due to several factors:
• Local and world environmental changes that allow mosquitoes to survive the winter months.
Researchers suggest the surge in dengue fever may be due to several factors:
•
International travelers who carry the disease to areas where mosquitoes have not been previously infected.
Dengue fever can be prevented by stopping mosquitoes from biting because they are the vectors the dengue viruses require for transfer to humans. The
CDC has supplied these general rules to prevent transfer of viruses and other pathogens by mosquitoes.
Avoid outbreaks: To the extent possible, travellers should avoid known foci of epidemic disease transmission. The CDC
Travelers'
Health web page provides alerts and information on regional disease transmission patterns and outbreak alerts.
Be aware of peak exposure times and places:
Exposure to arthropod bites may be reduced if travelers modify their patterns of activity or behavior. Although mosquitoes may bite at any time of day, peak biting activity for vectors of some diseases (for example, dengue, chikunguniya) is during daylight hours.
Use screens on doors and windows.
Repair broken or damaged screens quickly. Keep unscreened doors and windows shut.
Don’t give mosquitoes places to breed. Mosquitoes lay their eggs in water. So get rid of standing water in things like wading pools and gutters.
Change the water in birdbaths, dog bowls, and flower vases every few days.
Get your locality fogged in regular intervals.
Wear appropriate clothing: Travelers can minimize areas of exposed skin by wearing long-sleeved shirts, long pants, boots, and hats.
Bed nets: When accommodations are not adequately screened or air conditioned, bed nets are essential to provide protection and to reduce discomfort caused by biting insects. If bed nets do not reach the floor, they should be tucked under mattresses.
Insecticides: Aerosol insecticides, vaporizing mats, and mosquito coils can help to clear rooms or areas of mosquitoes.
Optimum protection can be provided by applying repellents.
There are no vaccines currently available commercially for dengue virus. However, researchers are actively trying to produce vaccines that will protect people from all dengue virus types.

Do not panic”…. Say the doctors.
