COVID-19肺炎的血清流图表明,中国人群总体处于SARS-CoV-2的低感染水平.
据新华社报道, 北京, 十二月 29 (Reporter Tian Xiaohang Mu Tiecheng), 记者从中国疾病预防控制中心获悉,中国遏制第一波COVID-19肺炎一个月后, 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, 仅有的 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 (北京, 辽宁, 上海, Jiangsu, Guangdong and Sichuan). 多于 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.
