In relation to Corona 19, many studies have shown that most of the confirmed cases do not infect other people, and a small number of confirmed cases with strong contagion have caused a pandemic.

Regarding the response, the quarantine authorities seem to have something to be consulted.

Corona 19 is known to have a strong transmission power, so that one patient usually infects two others.



However, a study in Japan found that close to 80% of corona19 confirmed cases do not infect others, and a study in Hong Kong also found that close to 70% had no transmission power.



Most of the confirmed cases do not have an infectious history. How was the global pandemic possible?




The world's most prestigious science magazine analyzed this as'super propagation'.



It is not that one corona19 patient infects two other people evenly, but four out of five confirmed cases do not infect others, but the other one infects eight.



[Myung-don Oh / Professor of Infectious Diseases, Seoul National University (Clinical Committee for New Infectious Diseases): 80% of confirmed cases do not cause any secondary infection, and the remaining 20% ​​cause most infections.]



Super transmission is not due to humans, but in an enclosed space. It is caused by the so-called'three mill' environment in which people are densely contacted.



In February this year, at the Boston Society of America, 97 people were infected, the first'super transmission' in the United States, and in the end, more than tens of thousands of confirmed cases are representative.



In this case, it is more efficient to prevent'super propagation' than to isolate close contacts by tracking back all confirmed cases.



[Myung-Don Oh/Professor of Seoul National University's Infectious Diseases (Clinical Committee for New Infectious Diseases): Unless all confirmed cases are spreading the same, it is possible to prevent the spread more efficiently if management is focused on these three-packed spaces and our activities within them.

Central Clinical Committee for New Infectious Diseases in Korea will soon announce the results of the analysis on super transmission blocking.
