(EVD) is a severe disease that causes hemorrhagic fever in humans and animals . Diseases that cause hemorrhagic fevers, such as Ebola, are often fatal as they affect the body's vascular system (how blood moves through the body). This can lead to significant internal bleeding and organ failure. It is not known exactly how humans first become infected with the Ebola virus.
Recent evidence suggests that humans may initially get the virus through contact with infected animals. Once a person is infected, the virus can spread through person-to-person contact. Ebola can be spread through: ? contact with infected animals (bats, monkeys, gorillas, pigs, etc.) ? contact with blood, body fluids or tissues of infected persons ? contact with medical equipment, such as needles, contaminated with infected body fluids The disease typically occurs in outbreaks in tropical regions of Sub-Saharan Africa. From 1976 when it was first identified through 2013, the World Health Organization reported 1,716 confirmed cases.
The largest outbreak to date is the ongoing 2014 West Africa Ebola virus outbreak, which has caused a large number of deaths in Guinea, Sierra Leone, and Liberia. Initial symptoms include sore throat, fever, chills, headache, muscle pain and weakness. As the disease gets progressed the symptoms get severe and include rash, nausea, vomiting and diarrhea, haemorrhaging (bleeding from inside and outside the body). Ebola is diagnosed based on travel history, symptoms and laboratory testing. There is currently no specific licensed treatment or vaccine for EVD. Patients are treated for their symptoms.
