Answers
Answer:
How does COVID-19 mostly spread?
The virus spreads mainly through the air when people are near each other. It leaves an infected person as they breathe, cough, sneeze, or speak and enters another person via their mouth, nose, or eyes. It might also spread via contaminated surfaces.
Where did COVID-19 come from?
The first known infections from SARS-CoV-2 were discovered in Wuhan, China. The original source of viral transmission to humans remains unclear, as does whether the virus became pathogenic before or after the spillover event. Because many of the early infectees were workers at the Huanan Seafood Market, it has been suggested that the virus might have originated from the market. However, other research indicates that visitors may have introduced the virus to the market, which then facilitated rapid expansion of the infections.
What is the recovery time for the coronavirus disease?
They found that for people with mild disease, recovery time is about two weeks, while people with severe or critical disease recover within three to six weeks.
