Scientists are still trying to unravel the mystery surrounding the transmission of the SARS-CoV-2 coronavirus between humans and the role of the so-called super-carriers. How is it that some people are able to infect several dozen others, and others, despite being infected, do not transmit the coronavirus further?
- Scientific research says that in the case of COVID-19 transmission, the so-called super-carriers. 10-20 percent infected is responsible for 80 percent. subsequent infections
- Scientists, on the basis of mathematical models, are trying to answer the question of when a person infected with coronavirus becomes a supercarrier
- From the latest scientific reports, we learn that not only the person of the super-owner is important, but also the time and place where he is
How does the coronavirus spread among people? Why do some infect dozens of people, while others do not transmit the infection further? Models developed by analysts from academic centers show that most infected people do not transmit the coronavirus further, yet the infection spreads rapidly. The so-called super carriers that can infect up to several dozen people.
“There is a small percentage of people who can infect many people,” said Dr. Joshua Schiffer, a physician and mathematical modeling expert who studies infectious diseases at the Fred Hutchinson Cancer Research Center in Seattle. Estimates of virus transmission vary by population, but typically show similar variations – between 10% and 20%. infected people may be responsible for 80 percent. new infections. Other diseases of the respiratory system, such as influenza, spread much more egalitarily (each infected person infects with a similar ‘effectiveness’).

Scientists are still trying to figure out what influences the rate at which the coronavirus spreads, as answering this question could be crucial to contain the pandemic. “That’s the million dollar question,” said Ayesha Mahmud, who studies the dynamics of infectious disease at the University of Berkeley.
A Super Carrier is a person who is in the wrong time and place
Dr. Schiffer and his colleagues have published an unreadable article on the medRxiv website in which they try to answer key questions about the spread of the SARS-CoV-2 coronavirus in the community. In their opinion, a supercarrier is a person who at a given moment has reached the point of infection where he infects most effectively and at the same time is in a large group of potentially infected people.
According to what scientists have established, the most risky window, i.e. the moment when we most effectively infect, can be very short and last 1-2 days a week in which a given person becomes infected. An infected person may continue to spread the infection beyond this time frame, but the longer the infection lasts, the less likely it is that the person is effectively infecting.
The big problem is to “catch” the moment when the infected person is in this most risky window. Some people infected with the coronavirus begin to show symptoms within a few days, while others may become sick even weeks after infection. The coronavirus incubation period ranges from 3 to even 21 days. In the case of flu, the incubation period is much shorter and the symptoms of the disease appear rapidly within days of infection.
If an infected person reaches the point of infection where they most effectively infect, and they do not develop symptoms, this increase can be very difficult to identify. The Super Carrier can then infect unconsciously.
The analysis carried out by the scientists showed one more important thing. A growing body of evidence suggests that coronavirus particles can persist in the air in crowded and poorly ventilated rooms where many people are present. Dr. Schiffer suggests that the coronavirus may be more prone to super spread than the influenza virus, for example, because it stays better in the air and can be transmitted over greater distances.

This, in turn, makes not only people who are close to the super-carrier (or other infected person) at risk of infection, but also those who are distant. Dr Shiffer also said that the phenomenon of superbearing is more circumstantial than an individual’s biology, although he does not deny that some people may be predisposed to ‘more effectively’ contaminate.
He also added that even a person at the peak of infection, which is when he infects most effectively, can stop transmission if he is careful: he will avoid large crowds and travel. Researchers also emphasize that it is helpful to protect other people from infection by wearing a mask that covers the mouth and nose and maintaining physical distance.
