Ebola Virus Disease (EVD) or simply Ebola, is an infectious and fatal disease. It is aused by four or five viruses of the Ebolavirus family. There is no treatment for the disease. Very few recover.
Ebola outbreaks occur primarily in remote villages in Central and West Africa. The virus is transmitted from wild animals to humans through contact with their blood and other bodily fluids. Wild animals that could be infected include monkeys, chimpanzees, antelopes, porcupines and fruit bats. The fruit bat is believed to be a natural host of the Ebola virus. It may harbour the virus without being affected by it. Once the virus has jumped to a human and he starts showing symptoms of the disease the virus can spread from him to others.
You cannot get Ebola from air, water or food. So far, Ebola cases have only shown up in Central and West Africa. The West African country of Liberia is one that is badly affected. Sierra Leone too is under threat from the virus.The rest of the world is keeping vigil at airports and other entry points to ensure that the disease doesn’t spread through travellers arriving from countries affected by the disease.
