A study in Wuhan, the Chinese city where Covid-19 was ‘born’, indicates that asymptomatic carriers of the virus may not spread.
The analysis, carried out by the journal Nature, was carried out between May and June and concluded that “There was no evidence of transmission from asymptomatic positive people to close contacts who were evaluated.”
According to the scientific journal, “In the present study, virus culture was performed on asymptomatic positive case samples and no viable SARS-CoV-2 virus was found”.
“All close contacts of positive asymptomatic patients had negative results, indicating that the positive asymptomatic cases detected in this study were probably not infectious.”.
The study involved nearly 10 million people.
The covid-19 pandemic caused at least 1,381,915 deaths as a result of more than 58.1 million cases of infection worldwide, according to a report by the French agency AFP.
In Portugal, 3,897 people died out of 260,758 confirmed cases of infection, according to the most recent bulletin from the Directorate General of Health.
The disease is transmitted by a new coronavirus detected at the end of December 2019 in Wuhan, a city in central China.
