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. Ebola also causes stiffness throughout the body which makes it hard for sick people to move.
Five to nine out of every ten people who get sick with Ebola die.
There is no cure for Ebola, but if people get care quickly from doctors and nurses at a hospital, more of them live. People with Ebola need a lot of fluids to replace fluids lost from diarrhea, vomiting, and bleeding. The most important care is giving them water with a very small amount of salt and sugar in it. This is called oral rehydration. It helps to replace their fluids and blood. It is also important to give medicines in case they get bad blood pressure and blood circulation.
Ebola is caused by infection with a virus of the family Filoviridae, genus Ebolavirus. There are five identified Ebola virus species, four of which are known to cause disease in humans: Ebola virus (Zaire ebolavirus); Sudan virus (Sudan ebolavirus); Taï Forest virus (Taï Forest ebolavirus, formerly Côte d’Ivoire ebolavirus); and Bundibugyo virus (Bundibugyo ebolavirus). The fifth, Reston virus (Reston ebolavirus), has caused disease in nonhuman primates, but not in humans.
Ebola viruses are found in several African countries. Ebola was first discovered in 1976 near the Ebola River in what is now the Democratic Republic of the Congo. Since then, outbreaks have appeared sporadically in Africa.
The natural reservoir host of Ebola virus remains unknown. However, on the basis of evidence and the nature of similar viruses, researchers believe that the virus is animal-borne and that bats are the most likely reservoir. Four of the five virus strains occur in an animal host native to Africa.Reblogged 3 years ago from www.youtube.com
