The share of super-distributors – those who are capable of infecting more people than the average infected person – in some regions can reach 80% or more, Alexander Semenov, head of the branch of the state scientific center of virology and biotechnology “Vector” of Rospotrebnadzor in Yekaterinburg, told TASS.
According to him, we are talking about regions, regions where people neglect masks, do not observe social distance, “crowd, hug, kiss, hang out all together.”
“Especially where the incidence tends to rise sharply, most likely in such regions it is necessary to track super-distributors,” Semenov said.
In July, associate professor of the Russian National Research Medical University named after V.I. Pirogova, infectious disease doctor Ivan Konovalov said that some people with COVID-19 can remain infectious for a long time. According to him, there are “some genetically unique people whose immune system is tolerant to the presence of the virus” – they excrete it much longer than others. “As a rule, these are asymptomatic carriers. We call such people “super-distributors”. There are not so many of them in percentage terms, ”he said.
Usually, a person who has recovered from COVID-19 ceases to be infectious within seven to ten days after the first symptoms appear, said the therapist Alexei Nikishenkov.
Doctor of Biological Sciences, Head of the Laboratory of Bionanotechnology, Microbiology and Virology of Novosibirsk State University (NSU), Corresponding Member of the Russian Academy of Sciences Sergey Netesov explained the asymptomatic course of COVID-19 by the so far unexplained features of immunity. According to him, it is those who carry the infection asymptomatically that become its distributors, since some of them do not wear masks. As an example, the academician cited a case in a choir in the United States, when among the singers there was a COVID-19 patient who was asymptomatic. “They sang for two hours, and after five days all 50 people fell ill,” Netesov said.
