The study was conducted by specialists from Singapore, writes DailyMail.

Scientists have found that the infected period begins about two days before the onset of symptoms of the disease (cough, fever) and lasts for 7-10 days after them.

But after 11 days, the person ceases to transmit the virus to others, even with a positive test for COVID-19. Despite the fact that testing finds particles of the virus, carriers of the infection are no longer dangerous to others.

“Active replication of the virus falls after the first week,” the study authors note. “After the second week of illness, his viability was not detected.”

Experts hope that the findings of the study will help doctors determine the timing of sending home hospitalized patients.

Scientists previously stated that the SARS-CoV-2 virus, which causes COVID-19, has a very high level of contagiousness because it combines the genomes of other coronaviruses. The authors of the corresponding study found that the genome of the new coronavirus is 96 percent composed of the genome of the SARS-CoV-1 virus, which killed 2003 people in 774. Moreover, SARS-CoV-2 also has the features of a benign human coronavirus HCoV-HKU1.
