A person who has had a coronavirus infection can shed the virus up to 90 days after recovery, Anna Popova, the head of Rospotrebnadzor, said on Tuesday.
“We have observations, the same observations are abroad, that a person who has recovered has a virus for up to 90 days. Our observations in the Russian Federation - up to 48 days, and abroad there are observations - up to 90 days. he has no symptoms, he feels great, he has excellent blood and all indicators, but he secretes the virus from his nose, "Popova said. Her words are quoted by TASS.
According to her, there is a great risk that the virus will remain in a functionally active state. "Therefore [после перенесенной инфекции или прививки] <... wp_automatic_readability="29.923922231615"> I will not suffer from this virus myself, but at the same time I can be a distributor of infection, this is important, "explained the head of Rospotrebnadzor.
In turn, the doctor of medical sciences, virologist Anatoly Altstein said that on average a person remains dangerous for two weeks. "But there may be exceptions, exceptions for such a long-term isolation of the virus. It is quite possible to get infected," he said.
In July, a team of international scientists led by specialists from the National Center for Epidemiology of Spain published the results of a study, from which it followed that a person who had recovered from COVID-19 could eventually lose immunity to coronavirus. 14% of the study participants, who had tested positive for antibodies two months earlier, did not show immunity during repeated testing, writes Forbes. Antibodies, as a rule, disappeared in people who had little or no symptoms with COVID-19, the scientific article said.
Later, researchers from the University of Hong Kong said that they were able to genetically confirm for the first time a case of re-infection with COVID-19. The virus was re-detected in a 33-year-old man four and a half months after the first infection. The first time he had to go to the hospital because of COVID-19, the second the disease was asymptomatic.
