The serum flow profile of pneumonia in COVID-19 shows that the population in China is generally at a low infection level in SARS-CoV-2.

据新华社报道, Beijing, 十二月 29 (Reporter Tian Xiaohang Mu Tiecheng), the reporter learned from the Chinese Center for Disease Control and Prevention that one month after China curbed the first wave of COVID-19 pneumonia, the Chinese Center for Disease Control and Prevention adopted cross-sectional survey methods in representative areas to carry out seroepidemiological investigation and analysis of pneumonia in COVID-19. The survey results show that the population in China is generally at a low infection level in SARS-CoV-2, indicating that the control of the epidemic situation in Wuhan is successful, which effectively prevents the large-scale spread of the epidemic situation.

It is understood that the survey found that the positive rate of COVID-19 antibody in the community population in Wuhan was 4.43%, and that in other cities and States in Wuhan, Hubei was 0.44%. 然而, only 2 cases were detected in more than 12,000 people in six provinces except Hubei, and the positive rate was extremely low. The antibody positive rate of people who have been exposed to confirmed cases of pneumonia in COVID-19 is significantly higher than that of other people, and the antibody positive rate of middle-aged and elderly people is higher than that of other age groups.

The survey covers three types of areas, including Wuhan City, cities and States outside Wuhan, Hubei Province and six provinces outside Hubei Province (Beijing, Liaoning, 上海, Jiangsu, Guangdong and Sichuan). More than 34,000 people in the community were selected by sampling survey design, and the infection level of SARS-CoV-2 in the population was estimated by detecting the serum SARS-CoV-2 antibody of the investigated subjects.
