Millions more locked down as China battles Omicron spread

China is currently battling local flare-ups in multiple cities.

Five million residents of a central Chinese city started home confinement on Tuesday in a new lockdown to curb the spread of the highly transmissible Omicron variant of the coronavirus, according to state media.

China is on high alert for new outbreaks as it prepares to host the Winter Olympics next month, sticking to a "zero-COVID" strategy.

While those measures have kept the number of new cases far lower than virus hotspots in the United States and Europe, China is currently battling local flare-ups in multiple cities.

The fast-spreading Omicron strain presents a fresh challenge, with two cases in Anyang – the newly locked-down city in Henan Province – linked to a growing infection cluster in the northern metropolis of Tianjin, some 400 kilometers away.

Authorities in Anyang announced the lockdown late on Monday, issuing a notice ordering residents not to leave their homes, state news agency Xinhua reported.

All non-essential businesses have been closed and a mass-testing drive has been launched "to respond to the severe epidemic control situation and strictly prevent the spread of the Omicron virus outbreak," Xinhua reported.

There were 58 new local infections reported in Anyang, state broadcaster CCTV said on Tuesday, bringing the city's total caseload to 84 since Saturday.

It was not immediately clear whether the new cases were tied to the Omicron variant.

At least three cities in Henan are battling emerging outbreaks, with provincial capital Zhengzhou closing schools and kindergartens, and stopping restaurants from accepting dine-in customers.

Millions more locked down as China battles Omicron spread

Medical workers take swab samples from citizens for nucleic acid test at a COVID-19 testing site in Zhengzhou, central China's Henan Province, on January 10.

Last week, one million people in the city of Yuzhou were put under stay-at-home orders.

Elsewhere, Tianjin – a major port city just 150 kilometers from Beijing – has barred people from leaving without official permission, ordered the testing of all 14 million residents, and canceled trains into the capital.

Tianjin is adjacent to Winter Olympics venues in Beijing and Hebei Province and confirmed another 10 new locally transmitted cases after citywide mass testing.

The northwestern city of Xi'an is in its third week of lockdown as it attempts to stamp out a 2,000-case outbreak.

And after logging a handful of cases in recent days, Shenzhen in southern Guangdong Province has locked down some housing compounds, launched a mass-testing initiative and shuttered some long-distance bus stations.
