Beijing, Dec 13 (PTI) China has reported a sudden flare-up of COVID-19 cases in Zhejiang Province which registered 138 locally-transmitted confirmed cases stated to be that of Delta strain "sub-lineage AY.4", prompting officials to bar millions of people in the eastern province from travelling outside.

Zhejiang Province has registered 138 locally-transmitted confirmed COVID-19 cases and one asymptomatic carrier between December 5-12, amid the latest COVID-19 resurgence, state-run Xinhua news agency reported on Sunday.

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.

The whole-genome sequencing and analysis found that the cases in the three cities were caused by the Delta strain sub-lineage AY.4, which is stated to be more transmissible and carries a higher viral load than the original novel coronavirus, the report quoted an official with the Zhejiang provincial centre for disease control and prevention as saying.

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