(Fighting New Coronary Pneumonia) Experts talk about Wuhan's response to this round of epidemic: "Early, accurate, and strict"
China News Service, Wuhan, August 11 (Reporter Zhang Qin) "In response to the'three high' characteristics of the delta mutant virus, Wuhan adopts an'early, accurate, and strict' response strategy." The Wuhan new crown epidemic prevention and control held on the 11th At the work press conference, Tan Xiaodong, a professor of public health at the School of Health of Wuhan University, introduced that all cases in Wuhan are currently actively checked from the isolation and control area, and they have been found through nucleic acid testing and screening.
According to the report of the day, as of 24:00 on the 10th, there are 76 confirmed cases of new coronary pneumonia and asymptomatic infections in Wuhan. Except for one case from a medium-high-risk area in another province, the remaining cases are all related to a tour group in Huaian, Jiangsu.
Previously, local officials announced that the sequencing results of the samples of confirmed cases showed that they were delta-type, and were highly homologous to the local case strains in this round of Jiangsu.
"Delta mutant virus has the characteristics of high viral load, high variability, and high uncertainty." Tan Xiaodong introduced that from the perspective of pathogenic biology research, the virus spreads fast, has a short incubation period, and is easy to spread rapidly in the population. , And there are many asymptomatic infections, which has become a difficult point in prevention and control.
Since the Wuhan Economic Development Zone reported on August 2 that a cluster of infections occurred at the Wuhan Zhuankou project site of the China Construction Third Bureau, Wuhan has completed the first round of nucleic acid tests for all employees, and key control areas and populations have undergone multiple rounds of screening.
In addition, apart from delimiting parts of Wuhan Economic Development Zone and Jiangxia District where cases are relatively concentrated, the city has also implemented closed management of nearly 160 communities.
In Tan Xiaodong’s view, Wuhan’s measures to deal with this round of the epidemic can be summarized as "early, accurate, and strict", that is, to contain the spread of the virus at the fastest speed, and to concentrate suspicious cases in the control area through precise sealing and control. And gradually expand the scope of containment control according to current trends to avoid the formation of large-scale spillovers.
He believes that the implementation of closed control management of some communities is a strategy that must be adopted as soon as possible for mega cities such as Wuhan.
Combining the distribution range and characteristics of the confirmed cases and asymptomatic infections in Wuhan, Tan Xiaodong analyzed that the source of transmission of all cases is clear, and the transmission chain and route are clear, showing a local concentration.
In addition, most of the reported cases of this round of epidemics were asymptomatic infections, and the confirmed cases were all mild or common, with no severe or critical illness.
