The virus that causes COVID-19 is mainly transmitted through droplets generated when an infected person coughs, sneezes, or exhales. These droplets are too heavy to hang in the air and quickly fall on floors or surfaces.
You can be infected by breathing in the virus if you are within close proximity of someone who has COVID-19, or by touching a contaminated surface and then your eyes, nose, or mouth.
The first fatal case of SARS-CoV-2 infection had continuous exposure to Wuhan Market; China was admitted with a 7-day history of fever, cough and dyspnoea. After 5 days of onset of illness, the wife of the patient who had no known history of exposure to the market, also had pneumonia and hospitalized in the isolation ward. The SARS-CoV-2 infection has so far caused clusters of severe respiratory illness like severe acute respiratory syndrome coronavirus and was associated with ICU admission and high mortality in China.
