BEIJING (REUTERS) - China's new locally transmitted Covid-19 cases spiked to a near three-month high and tighter curbs to contain the spread are expected in the capital Beijing in the run-up to a key gathering of the highest-ranking members of the Communist Party next week.

The National Health Commission confirmed on Wednesday (Nov 3) 93 new local symptomatic cases for Tuesday, up from 54 a day earlier and the highest daily count since Aug 9 at the peak of China's last major outbreak.

Beijing reported eight new local infections, the most since Jan 19.

While the new cases accrued each day by the Chinese capital city since late last month have remained very modest compared with outside of China, the country's zero-tolerance policy has meant the imposition of strict measures to contain the spread of the virus at all costs.

Temperature screening has been set up at entrances of shopping malls, supermarkets, hotels, cinemas and subway stations, while a legion of staff on the ground check the health codes of visiting individuals on their mobile phones.

Beijing authorities have also repeatedly told residents to refrain from travelling out of the city, postpone weddings, simplify funeral arrangements and cut back on all non-essential gatherings.

Of the flights scheduled on Wednesday at Beijing Daxing Airport, 60.4 per cent have been cancelled as at the morning, while 49.8 per cent of flights at Beijing Capital Airport have been scrapped.

The rise in Beijing infections comes as the 300-plus members of the Communist Party's Central Committee prepare to gather in a major closed-door meeting from Monday to Nov 11.

It will be the committee's sixth and penultimate so-called plenum of its five-year term before the next big Party Congress next year.

At the plenum, President Xi Jinping is expected to push through a resolution that will cement his authority and legacy, and strengthen his case for a precedent-breaking third term starting next year.

Outside of Beijing, new local infections were reported in the north, north-east and north-west in provinces and areas including Heilongjiang, Hebei, Gansu, Inner Mongolia, Ningxia and Qinghai.

New cases were also seen the south-west of China, in the municipality of Chongqing, as well as the provinces of Sichuan and Yunnan.

The southern province of Jiangxi reported two new cases.

Inclusive of cases imported from overseas, China reported 109 new confirmed infections for Tuesday compared with 71 a day earlier.

As at Tuesday, mainland China had 97,423 confirmed cases.
