Cause: Ebola virus
Illness and treatment: Maximum incubation period is 21 days. Illness begins with abrupt onset of fever, headache, and muscle aches progressing after about five days to watery diarrhea, vomiting and abdominal pain. Later signs can include internal and external bleeding, and multi-organ failure; 60-90% of cases are fatal. Treatment is supportive.
Sources: Ebola virus disease occurs in parts of Africa. Initial transmission from an unknown mammalian reservoir can be followed by person-to-person transmission through direct contact with body fluids or excreta (blood, urine, diarrhea, vomit, sweat, semen, milk) including percutaneous injection, mucous membrane contamination, or contact with corpses. Viremia occurs with onset of symptoms, peaking around day 10.
Prevention: Strict adherence to infection control measures is essential when treating patients potentially infected with Ebola virus disease.
Recent Washington trends: No cases have occurred in the state.
