Is 10 days of quarantine enough time to get rid of the coronavirus from the body? According to scientists, no. In almost one in 10 people, the SARS-CoV-2 coronavirus is active for more than 10 days.
In 13 percent People infected with the SARS-CoV-2 coronavirus, this pathogen may be active even after 10 days of quarantine, according to research by scientists from the University of Exeter in the UK. In their opinion, this group could still be a source of infection.
The researchers used a new test for their research that shows whether the SARS-CoV-2 virus is active or not. A standard PCR test only detects virus particles that are indicative of its presence in the body, but not of its activity.
Is 10 days of quarantine enough?
The study involved 176 people infected with the SARS-CoV-2 coronavirus, who were tested with a new test. It turned out that after 10 days of isolation, as many as 13 percent of them still had an active virus in their bodies. There were also patients in whom this pathogen remained active for 68 days!
– From the medical point of view, these patients did not stand out – they did not have any distinctive features – explained Prof. Lorna Harries from the University of Exeter, one of the authors of the study, added that in her opinion the new test would be very useful in places where people are at high risk of infection, such as nursing homes or hospitals.
Where is the test necessary?
Merlin Davies of the University of Exeter, lead author of the study, is of a similar opinion: ‘There are places, such as nursing homes, where returnees can continue to infect others after having had an illness, and therefore constitute a serious public health problem. It would be good to make sure that people in such facilities do not carry the active virus and can no longer infect others.
