According to reports, from July 3rd to July 9th, more than 200 cases of local positive infections have been reported in Shanghai, most of which are related to the related epidemic related to KTV on No. 148 Lanxi Road in Putuo District.

The research results also show that vaccination can still effectively prevent critical illness and death after BA.5 infection.
