　　According to Yang Dasuo’s analysis, the total number of nucleic acid samples collected by all employees in the city has changed in three rounds, of which the second and third rounds are less than the first round, because some qualified college students left Nanjing for holidays and other reasons. In addition, the number of samples in the second round was significantly lower than that in the first round, and other streets such as Jiangning and Lukou carried out the second round of testing ahead of the whole city, and the relevant sampling numbers were included in the figures of the first round of sampling. At present, there are 12 provincial, municipal and district centers for disease control and prevention in Nanjing, and the city’s single-tube nucleic acid detection capacity has exceeded 700,000 copies per day.
