Ebola - Signs and Symptoms

Ebola first appeared in 1976 in 2 simultaneous outbreaks, in Nzara, Sudan, and in Yambuku, Democratic Republic of Congo. The latter was in a village situated near the Ebola River, from which the disease takes its name.

Key facts

• Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans.
• EVD outbreaks have a case fatality rate of up to 90%.
• EVD outbreaks occur primarily in remote villages in Central and West Africa, near tropical rainforests.
• The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission.
• Fruit bats of the Pteropodidae family are considered to be the natural host of the Ebola virus.
• Severely ill patients require intensive supportive care. No licensed specific treatment or vaccine is available for use in people or animals.

Symptoms of Ebola  typically include

• Fever (greater than 38.6°C or 101.5°F)
• Severe headache
• Muscle pain
• Weakness
• Diarrhea
• Vomiting
• Abdominal (stomach) pain
• Lack of appetite

Symptoms may appear anywhere from 2 to 21 days after exposure to ebolavirus, although 8-10 days is most common.

Some who become sick with Ebola are able to recover. We do not yet fully understand why. However, patients who die usually have not developed a significant immune response to the virus at the time of death.
