Causes, incidence, and risk factors:
Ebola hemorrhagic fever (Ebola fever) is a viral disease that is limited to parts of Africa. It has been newsworthy worldwide because of its destructive potential. The exact mode of transmission is not understood. The incubation period appears to be up to 1 week, at which time the patient develops fatigue, malaise, headache, backache, vomiting, and diarrhea. Within a week, a raised (papular) rash appears over the entire body. The rash is often hemorrhagic (contains blood). Hemorrhaging generally occurs from the gastrointestinal tract, causing the patient to bleed from both the mouth and rectum. Mortality is high, reaching 90%. Patients usually die from shock rather than blood loss.
