Route of infection
Ebola virus disease, also known as "Ebola haemorrhagic fever" (EHF), is a rare but lethal infectious disease. The biosafety level of Ebola virus reached level 4 (AIDS was level 3, SARS was level 3, the greater the level, the more strict the protection).
The transmission of Ebola virus is mainly through human body fluids, including saliva, blood, vomit, feces and so on.Some researchers think that air is also a way for Ebola virus to spread.Because it was found in the study that the antibody of the virus was positive in the sera of six staff members who were in close contact with the sick monkeys every day, five of them had no trauma or injection history, so it was considered that the virus could be transmitted through droplets.
To control the spread of Ebola, we should first pay close attention to the epidemic situation of Ebola virus in the world, and isolate and observe the suspected patients with bleeding symptoms.Once the diagnosis is confirmed, it should be reported to the health department in time to isolate the patients most strictly, that is, to use the isolation equipment with air filter.Medical and experimental personnel should wear isolation suits, and if possible, space suits for inspection and operation to prevent accidents. Those who have close contact with patients should also be closely observed.
