RIO DE JANEIRO, BRAZIL - Patients who suffered the most severe form of Covid-19, a disease caused by Sars-Cov-2, had the virus in their system for a longer period than those who had mild cases of infection.
In samples taken from the respiratory tract (phlegm and saliva) of more severe patients in China, the virus was found for 21 days on average. In some cases, this period extended to 30 days. The average lifespan of the virus in patients without complications was 14 days.
The results stem from a study published by Chinese scientists on Tuesday, April 21st . . .
