What causes Ebola virus hemorrhagic fever?

Ebola virus hemorrhagic fever is an acute infectious disease caused by infection with the Ebola virus. The virus is mainly transmitted through the following routes: 1. Direct contact with animals carrying the virus, such as bats, fruit flies, apes, monkeys, etc., is a direct cause of Ebola virus hemorrhagic fever. 2. Contact with blood, bodily fluids of patients infected with Ebola virus, or direct contact of broken skin or mucous membranes with virus-containing liquids can also lead to infection. 3. Contact with objects contaminated by the Ebola virus, such as sharing drinking cups, reuse of contaminated needles, etc., may also lead to transmission. In addition, the semen of a small number of male Ebola virus disease patients after recovery may contain the virus, and transmission can also occur through sexual activity. Ebola virus hemorrhagic fever has an extremely high fatality rate, and patients may experience widespread systemic hemorrhage requiring urgent medical intervention.
