At the construction site where people gather. This round of epidemic in Changzhou occurred at a construction site where people gathered. From the screening of key people returning from other provinces and cities in Changzhou on the evening of March 12, it was found that 1 human nucleic acid detection was positive at the initial screening. As of June 17, Changzhou has reported a total of 27 confirmed cases, with 4 asymptomatic infections per person.

Epidemic characteristics of Changzhou city

In this round of epidemic, the virus gene sequencing results of Changzhou positive infected people belong to Omicron mutant strain (the evolutionary branch of BA.2), and the virus has strong concealment, strong infectivity and extremely fast speed, which is easy to form community transmission. Wearing a mask is still the most effective way to do personal protection.

Outside the school gate of Changzhou Sanhekou Middle School, a parent who picked up his children from school did not wear a mask, which caused the virus to spread rapidly in a certain range and infected more than 30 people. I would like to remind the general public once again that in daily life, we must adhere to the norms of wearing masks, consciously do personal protection, actively cooperate with epidemic prevention and control measures, minimize crowd gathering, let Changzhou temporarily calm down, and control the spread of the epidemic as soon as possible.
