10 percent of those infected cause 80 percent of new infections, British researchers at the London School of Hygiene and Tropical Medicine (LSHTM) believe.

Thus, many corona infected people would never infect another person: “Most people do not transmit the disease,” says lead researcher Adam Kucharski about “Science”.

The case threw South Korea back several months in combating the pandemic: the country eased the measures at the beginning of May after the spread of the corona virus was almost stopped there. Then a 29-year-old visited several clubs in Seoul and infected over 50 people. The man was later tested positive for the corona virus.

Experts speak of so-called superspreader events, in which a highly infectious person infects several people at once. A British team of researchers from the London School of Hygiene and Tropical Medicine (LSHTM) has now taken a close look at the phenomenon and in the science magazine “Science” released.

“Most people don’t transmit the disease”
The British researchers assume that the superspreaders are far more important than previously thought: around 10 percent of those infected with corona would cause over 80 percent of new infections.

Superspreader especially infectious for two days
Why some people are so much more contagious than others could not be finally clarified. A possible immune deficiency is at least only one of many potential factors, according to the researcher.

However, more is known about the spread through the superspreaders: there is much to suggest that the environment and the time of contact play a major role. Kucharski: “Two days later, this person could behave the same way and you wouldn’t see the same result.” The researchers believe that superspreaders are particularly infectious only for a short period of time.
