A 26-year-old woman in China's capital Beijing who contracted the omicron strain of COVID-19 has drawn national attention on social media for her shopping trips.
The woman, who has not been identified by name, reportedly visited high-end shops in the city before showing symptoms of having the virus.
It wasn't known where or how she became infected and her present condition hasn't been made public.
The woman's case was widely discussed online and reflects the government's painstaking efforts to track down and isolate every virus case, along with identifying and testing anyone an infected person may have been in contact with.
The first reported case of the omicron variant has prompted stepped-up measures in Beijing, just weeks before it hosts the Winter Olympic Games.
More than 13,000 people and all places visited by the 26-year-old woman have been tested and her apartment complex and workplace sealed off.

Officials across the country also urged residents to stay in their cities for the new year, instead of traveling back to their hometowns.
Tourist sites, including sections of the Great Wall, have also closed amid China's zero-COVID" policy that has seen millions of people placed under lockdowns.

Following three weeks of isolation, the ancient capital of Xi'an appeared to be turning a corner, with stay-at-home rules lifted on neighborhoods determined to be virus-free.
