August 31, a sudden outbreak of an epidemic in Changchun City: 5 cases of inpatients with positive nucleic acid were found in the routine nucleic acid test of Changchun Infectious Diseases Hospital, and none of the inpatients had any social activity track in the past 7 days .

As of 24:00 on September 4, a total of 15 new local confirmed cases and 173 asymptomatic infections were added in Changchun City. The infected persons are all hospital inpatients, inpatient escorts, medical nurses and staff, outpatient visits and escorts.

The epidemic affects 4 cities around Changchun

On September 4, Wu Jing, deputy director of the Changchun Municipal Health Commission, said that asymptomatic infections accounted for a large proportion of those infected in this round of epidemics, which was in line with the Omicron BA. 5.2.1 Onset characteristics.

The “medical community” noticed that 173 of the 188 infected people were asymptomatic, accounting for 92.0%.

The evolutionary branch of BA.5.2 spreads rapidly and is highly concealed, and the nucleic acid positive time of a small number of infected people lags behind the onset time. The latest research in South Africa shows that the R0 value of the BA.5 mutant strain is as high as 18.6, which is the most infectious virus at present.

The epidemics in Xinjiang, Shenzhen, Zhejiang Yiwu and Dalian were all caused by BA.5.2.1. In order to prevent and control BA.5, which has strong transmission power, Dalian City advocates wearing N95 and above masks in certain places.
