People can get EVD through direct contact with an infected animal (bat or nonhuman primate) or a sick or dead person infected with Ebola virus.Is Covid an airborne virus?

What's the Ebola death rate?
The disease kills between 25% and 90% of those infected—about 50% on average. Death is often due to shock from fluid loss, and typically occurs between six and 16 days after the first symptoms appear.
Which is deadlier Ebola or Covid?
In the largest Ebola outbreak in West Africa, there were 28,616 cases of Ebola virus disease and 11,310 deaths, for a death rate of 39.5% (low compared to historic death rates for Ebola Zaire). If we only had 28,616 cases of COVID-19, at the current death rate of 4.1%, that would translate to 1,173 deaths.
Is Ebola curable?
There’s no cure for Ebola, though researchers are working on it. There are two drug treatments which have been approved for treating Ebola. Inmazeb is a mixture of three monoclonal antibodies (atoltivimab, maftivimab, and odesivimab-ebgn).

How long COVID-19 stays in the body varies from person to person. Generally, people are no longer contagious about 10 days after the onset of symptoms. A recent study found that people can be shed the virus for as long as 83 days, underscoring the importance of frequent testing, quarantining, and isolation practices.
