After the control of Lacey No. 7 Middle School, some confirmed cases were found in the close contacts of the three students. On March 5, Qingdao held a press conference on epidemic prevention and control, informing that the epidemic had been hidden and spread in the school for a period of time, and because it was a day school, the infection of the students would spread to family members and cause a greater risk of community transmission.
After this, students, their family members and other related infected persons were quickly diagnosed one by one.

As for the characteristics of this round of epidemic prevention and control and whether it can “lie flat” in the face of Omicron, Zhang Zhang, director of the National Center for Infectious Diseases Medicine and leader of the Shanghai New Coronary Pneumonia Clinical Treatment Expert Team Wen Hong expressed his opinion. “I don’t agree with ‘laying down’. If the epidemic spreads, it may result in a relatively high death price.”
Zhang Wenhong believes that the current overall strategy for fighting the epidemic is to “accumulate a small victory into a big victory”. Although a few people may be at home, most people still maintain normal work. Although some units will be closed due to various reasons in the near future, the closed methods and methods, for the future, need to be broken through.
When talking about the future anti-epidemic work, Zhang Wenhong said that the anti-epidemic can not only “clear” the society, but also make the city or the people living in it to the greatest extent possible. The environment will be less affected, the extent of the shutdown will be less, and the number of people under control will be less. This means progress has been made.
