Ebola virus disease (EVD), also known as Ebola hemorrhagic fever (EHF) or simply Ebola, is a viral hemorrhagic fever of humans and other primates caused by ebolaviruses. Signs and symptoms typically start between two days and three weeks after contracting the virus with a fever, sore throat, muscular pain, and headaches. Then, vomiting, diarrhea and rash usually follow, along with decreased function of the liver and kidneys. At this time some people begin to bleed both internally and externally. The disease has a high risk of death, killing between 25 and 90 percent of those infected, with an average of about 50 percent. This is often due to low blood pressure from fluid loss, and typically follows six to sixteen days after symptoms appear.
The virus spreads by direct contact with body fluids, such as blood, of an infected human or other animals. This may also occur through contact with an item recently contaminated with bodily fluids. Spread of the disease through the air between primates, including humans, has not been documented in either laboratory or natural conditions.Semen or breast milk of a person after recovery from EVD may carry the virus for several weeks to months.Fruit bats are believed to be the normal carrier in nature, able to spread the virus without being affected by it. Other diseases such as malaria, cholera, typhoid fever, meningitis and other viral hemorrhagic fevers may resemble EVD. Blood samples are tested for viral RNA, viral antibodies or for the virus itself to confirm the diagnosis.
A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells.
Basic structural characteristics, such as genome type, virion shape and replication site, generally share the same features among virus species within the same family.
There are five double-stranded DNA families: three are non enveloped (Adenoviridae, Papillomaviridae and Polyomaviridae) and two are enveloped (Herpesviridae and Poxviridae). All of the non-enveloped families have icosahedral capsids.
There is one family of partly double-stranded DNA viruses: Hepadnaviridae. These viruses are enveloped.
There is one family of single-stranded DNA viruses that infect humans: Parvoviridae. These viruses are non-enveloped.
There are seven positive single-stranded RNA families: three non enveloped (Astroviridae, Caliciviridae and Picornaviridae) and four enveloped (Coronoviridae, Flaviviridae, Retroviridae and Togaviridae). All the non-enveloped families have icosahedral nucleocapsids.
Ebola virus (/ɛˈboʊlə/;EBOV, formerly designated Zaire ebolavirus) is one of five known viruses within the genus Ebolavirus. Four of the five known ebolaviruses, including EBOV, cause a severe and often fatal hemorrhagic fever in humans and other mammals, known as Ebola virus disease (EVD). Ebola virus has caused the majority of human deaths from EVD, and is the cause of the 2013–2015 Ebola virus epidemic in West Africa, which has resulted in at least 28,638 suspected cases and 11,315 confirmed deaths.
Ebola virus and its genus were both originally named for Zaire (now the Democratic Republic of Congo), the country where it was first described, and was at first suspected to be a new "strain" of the closely related Marburg virus. The virus was renamed "Ebola virus" in 2010 to avoid confusion. Ebola virus is the single member of the species Zaire ebolavirus, which is the type species for the genus Ebolavirus, family Filoviridae, order Mononegavirales. The natural reservoir of Ebola virus is believed to be bats, particularly fruit bats, and it is primarily transmitted between humans and from animals to humans through body fluids.

Video about 2014 Ebola Virus Disease: Liberia’s Brave Men Who Remove Ebola-Infected Bodies. The story is becoming all too common in Monrovia. A sick young woman refused to go to the hospital when health workers asked her, and the entire community, to do so. Now, the woman is dead and many of the community are infected with Ebola.

Ebola Virus, Ebola Virus infection, ebola virus video, ebola virus disease, ebola virus documentary Over 90 people have died so far in West Africas Ebola outbreak, which Doctors Without Borders (also known as MSF) is calling "unprecedented." And the deadly disease, reports indicate, is continuing to spread. Ebola is a frightening disease: It is one of the worlds most lethal viruses, and the CDC ranks it among anthrax and smallpox as a Category A bioterrorism agent. As some have pointed out, however, other diseases are taking a much bigger toll in the developing world. Ebola has killed 1,500 people in total since it was first documented in 1976. But the dramatic nature of Ebola aside, health workers say there are a number of reasons to believe this latest outbreak is particularly concernin...

Ebola, previously known as Ebola hemorrhagic fever, is a rare and deadly disease caused by infection with one of the Ebola virus species. Ebola can cause disease in humans and nonhuman primates (monkeys, gorillas, and chimpanzees). When people get Ebola the first symptoms look like some other diseases. People get a fever and feel very tired. Their head, stomach, joints, and throat might hurt. Sometimes, people think they have other diseases like malaria or typhoid fever. Later, people get much sicker. They bleed both inside and outside their bodies. They have blood in their diarrhea and vomit. They bleed from their noses, mouths, and genitals/sex organs. They get shock: low blood pressure, fast pulse (heart rate), and low blood circulation to the body. Their organs might stop working. Ebo...

Virus able to evolve, change your environment, jump from one species to another. Scientists continue its track. Looking hiding in nature, in animals that viruses use to travel from one place to another planet ... but not always find them. In recent decades there have been many diseases that so far only affected animals.

Ebola Virus Epidemic In this lecture given at Gresham college you will learn all about this serious infectious disease. Ebola has impacted the world and as of December of 2014 there have been 17,942 reported cases of Ebola. Of the cases reported, there have been 6388 deaths from ebola. It is believed the latest bout of the epidemic started when a 2 year old child came in contact with an infected bat or bat droppings. The first case of an ebola outbreak was recognized in 1976 in Zaire. It was named after a local river in the region. Of the 318 cases reported at that time, there was a 90% mortality rate. It is thought that the Ebola virus existed for much longer than that. Currently the motality rate for ebola is around 70%. It is thought that you can catch the disease from direct contact...
Ebolaviruses first infected human in 1976, but it was not until the 2014 outbreak, the largest ever, did they capture the world's attention. In this lecture we address five questions about Ebolaviruses: What are they, where did they come from, how do they replicate, how do they cause disease, and how can infection be prevented. And no, they did not go airborne during this outbreak in west Africa.
