1.What is Ebola hemorrhagic fever? Ebola hemorrhagic fever is an acute hemorrhagic infectious disease caused by the Ebola virus that occurs in humans and non-human primates (monkeys, gorillas and chimpanzees). 2.What is the source of Ebola virus infection? Human and non-human primates infected with Ebola virus are the source of infection of the disease. 3.What is the transmission route of Ebola hemorrhagic fever? Contact transmission is the most important way of transmission of the disease. It can be transmitted through contact with various body fluids, secretions, excretions and contaminants of patients and infected animals. 4.What are the typical signs and symptoms of Ebola virus infection? Typical signs and symptoms include sudden onset of fever, extreme malaise, muscle pain, headache and sore throat, conjunctival congestion, and relatively slow pulse. This is followed by nausea, vomiting, abdominal pain, diarrhea, mucus stools or bloody stools, and a skin rash. The incubation period of the disease is 2-21 days. It is not contagious during the incubation period and is contagious once the patient begins to show symptoms. Ebola infection can only be confirmed by laboratory testing. 5. When should people seek medical attention? People should seek medical attention immediately when they have been in an area where Ebola (virus) hemorrhagic fever is known to exist, or have been in contact with someone known or suspected to have Ebola (virus) hemorrhagic fever, and have begun to develop symptoms. When a patient is suspected of having the disease, it should be reported immediately to the nearest health facility. 6.How to prevent the disease? (1) Learn about the disease; (2) Follow the guideline documents issued by the national health authorities; (3) Encourage and support people in the vicinity to seek medical treatment at a health facility if they are suspected to be infected with Ebola; and (4) Proper protective equipment must be worn when handling fatal cases of Ebola. In addition, individuals should reduce contact with high-risk infected animals (e.g., fruit bats, monkeys, or apes) in affected tropical rainforest areas. If an animal is suspected to be infected, do not handle them again. Animal products (blood and meat) should be ensured to be cooked before being consumed.
