China has reported a spike in Covid-19 infections in Zhejiang province which registered 138 locally-transmitted confirmed cases stated to be that of new Delta strain ‘sub-lineage AY.4’, prompting authorities to bar millions of people in the eastern province from travelling.
This is the first time China has reported the new strain of the Delta variant of the coronavirus, state-run CGTN-TV reported. Zhejiang province has registered 138 locally-transmitted confirmed cases and one asymptomatic carrier between December 5 and 12, amid the latest Covid-19 resurgence, state-run Xinhua news agency reported.
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.

Local authorities have imposed restrictions on public gatherings and travelling out of the province to prevent the virus from spreading further. The province has a 64.6 million population.
