What is the root cause of the Shanghai epidemic in 2022?

One of the serious causes of the epidemic in Shanghai: management negligence

The epidemic in Shanghai is caused by overseas infection! Facing the Omicron mutant, the epidemic prevention and control offices in many places did not realize the infectivity and concealment of the virus. Not only did Jilin lose its head, but even Shanghai certainly didn't realize it, which led to the failure of accurate prevention and control and the rapid spread of the local epidemic.

The second reason for the serious epidemic situation in Shanghai: there are many asymptomatic infected people.

On March 29th and 30th, according to the new epidemic notified by Shanghai Health and Health Commission, there were more than 5,000 asymptomatic infected people. Among them, there were 5656 cases of asymptomatic infection on the 29th and 5298 cases of asymptomatic infection on the 30th in Shanghai. The reason why there are so many asymptomatic infected people in Shanghai is mainly related to the characteristics of Omicron variants, whose toxicity is relatively weakened and clinical symptoms are relatively mild, which will lead to many infected people having no clinical symptoms after infection.

Three reasons for the serious epidemic situation in Shanghai: global static management

On the evening of March 30, the epidemic conference held in Shanghai decided to adopt comprehensive prevention and control measures such as global static management, whole-process nucleic acid screening, comprehensive epidemiological investigation and national cleaning and disinfection. Static management in Shanghai means that all personnel can't move, can't leave, and are strictly controlled in an all-round way. All enterprises continue to close down (or work from home) except public service enterprises for people's livelihood security.
