According to reports, the confirmed cases were suspected to be carrying the virus between December 5 to 12. While most of them displayed vivid symptoms, one among the 138 was asymptomatic. The infections were confirmed after the mainland sent positive Covid samples for whole-genome sequencing. Following the confirmation of cases, local authorities have closed down inter-provincial borders and announced an array of measures like- restrictions on public gatherings, to curb the spread of the virus.

The report from Hangzhou, the provincial headquarters on Sunday said of the 138 in Zhejiang 44 cases were reported in Ningbo, 77 cases in Shaoxing and 17 cases were in the provincial capital of Hangzhou.
