Covid-19 surge: China registers a new daily high with 115 cases per day

China has recorded the biggest daily jump in Covid cases in more than five months, despite four cities being under lockdown, increased testing and other measures aimed at preventing another wave of infections in the world’s second biggest economy.

The National Health Commission (NHC) said in a statement that a total of 115 new confirmed cases were reported in the mainland compared to 55 a day earlier. This was the highest daily increase since July 30.

The commission said 107 of the new cases were local infections. Hebei, the province that surrounds Beijing, accounted for 90 of the cases, while northeastern Heilongjiang province reported 16 new cases.

Most of the new patients were reported near the capital Beijing, but a province in northeast China also saw a rise in new cases, official data showed on Wednesday, amid a resurgence that has seen more than 28 million people under home quarantine.
