A lockdown of 13 million people in the Chinese city of Xian entered its seventh day on Wednesday, with many unable to leave their residential compounds and virtually dependent on deliveries of necessities as new COVID-19 infections persisted.

Xian reported 151 domestically transmitted infections with confirmed symptoms for Tuesday, or nearly all of the 152 cases nationwide, bringing the total number of local Xian cases to nearly 1,000 during the Dec. 9-28 period. No cases of the omicron variant have been announced in the city so far.

While the Xian outbreak is small compared with outbreaks in many other places around the world, officials have imposed tough curbs on travel within and leaving the city from Dec. 23, in line with Beijing's drive to immediately contain outbreaks as they appear.
