Case Definition for Ebola Virus Disease (EVD)
Early recognition is critical for infection control. Healthcare providers should be alert for and evaluate any patients suspected of having EVD.
Suspected Case
Illness in a person who has both consistent symptoms and risk factors as follows: 1) Clinical criteria, which includes fever of greater than 38.6 degrees Celsius or 101.5 degrees Fahrenheit, and additional symptoms such as severe headache, muscle pain, vomiting, diarrhea, abdominal pain, or unexplained hemorrhage; AND 2) Epidemiologic risk factors within the past 3 weeks before the onset of symptoms, such as contact with blood or other body fluids of a patient known to have or suspected to have EVD; residence in?or travel to?an area where EVD transmission is active; or direct handling of bats, rodents, or primates from disease-endemic areas. Malaria diagnostics should also be a part of initial testing because it is a common cause of febrile illness in persons with a travel history to the affected countries.
Confirmed Case
A suspected case with laboratory-confirmed diagnostic evidence of ebolavirus infection.
