The National Health Commission this Saturday (1) reported 175 new infections in the community with clinical symptoms confirmed until December 31, bringing the number of cases in the mainland to 1,151 in China. The explosion at the Industrial Technology Center in northwestern Sian was the main reason for the increase in cases.

Although the number of cases dropped significantly earlier this year, China has maintained some of the toughest pandemic-fighting measures in the world.

The severity of the explosion in Zion, a city of 13 million people, is likely to underscore the authorities’ determination to step up efforts to prevent the spread of the virus in the event of a lawsuit.

Yunnan province, which shares an international border with Myanmar, Laos and Vietnam, reported 92 new local cases in 365 days last year, or 25% of the time, more than any other province, autonomous region or municipality.

New local cases were reported within 30 days in the Xian capital, Shanxi Province.

The Cyan outbreak has not yet seen a significant drop in cases. Authorities said the virus had spread quietly in the city before tightening controls.

The cause of the blasts, as well as cases in other cities, including Beijing, can be traced back to a flight from Pakistan, but it is not clear how the virus spread to local communities.

Many people have been barred from leaving their housing complexes, but when the time is right, barriers will be eased in low-risk areas, a city government official said Friday.

Lee Jiaxin, a 23 – year – old graduate student, said no one could leave her university campus. She spent New Year’s night with her three roommates and could not see her boyfriend and family.

“I’m considered a ritualistic person, so I’m still a little sad that we’re not together now,” she said.
