According to a CDC study in the United States, the basic number of infections in the new corona COVID-19 is 5.7, twice as high as previously thought of 2 or 3. This means that an infected person can infect up to six people, which is more difficult to control. Los Alamos National Laboratory analyzed data from Wuhan and came to this conclusion. Previous estimates put R0 between 2.2 -2.7.
The researchers say the results suggest that when the proportion of unidentified infections is low, isolating and tracking close contact with a symptomatic infected person is an effective way to slow the spread of the virus. Imperial College’s recently published RO number of 3.87,5.7 means that the new crown has a higher level of infection. Researchers point out that at least 82 percent of the population is immunized against the spread of the virus by vaccination or prior infection. The researchers believe that the situation in China, South Korea, Taiwan, Hong Kong and Singapore shows that it is possible to control the spread of the virus if early action is taken.
