In one in ten infected people, SARS CoV-2 may remain active after 10 days of quarantine. Researchers from the University of Exeter in the UK found that this means such a person would spread the infection. The work has been published in the International Journal of Infectious Diseases.

Scientists used a new test for their research, which shows whether the SARS-CoV-2 virus is active. Standard PCR tests detect virus particles that indicate their presence in the body, not their activity. 176 people infected with the new test were tested and it turned out that after 10 days of isolation, 13 percent had active virus. There have also been patients in whom the virus has remained active for 68 days.

Professor A. said: Lorna Harris of the University of Exeter.

The study authors acknowledge that the new test will be very useful in places where there are people who are at high risk of infection.

“There are places – such as nursing homes – where people coming back from illness can still infect others and thus pose a serious public health problem. “It would be good to reassure people in such facilities that they are not They are carriers of the active virus and can no longer transmit the infection to others.” He added that he wanted to continue research on a larger group of patients.
