The situation has taken on heightened urgency in China given Tianjin’s proximity to Beijing. Many commuters travel daily between the two cities, often using high-speed rail, which takes about 30 minutes.
In response to the threat of rising infection rates, Tianjin officials have quickly moved to enforce lockdowns in several affected neighborhoods. Widespread testing of the entire city was still underway on Monday. The authorities have also tightened travel restrictions into and out of Tianjin, requiring residents to obtain approval from employers or community officials before leaving. And starting Sunday afternoon, train tickets between Tianjin and Beijing were suspended for purchase.
But there were worrying signs that the Omicron variant had already spread beyond Tianjin. The central Chinese city of Anyang, in Henan Province, reported two local Omicron infections on Monday, traced to a student who had traveled from Tianjin on Dec. 28, spurring concerns that the Omicron variant may have already been circulating in Tianjin for nearly two weeks.
Millions of people in the Chinese cities of Xi’an and Yuzhou, in Henan Province, are also currently being confined to their homes following a recent surge in cases of the Delta variant.
The outbreaks have concerned officials in Beijing, who are stepping up measures to ensure that the virus does not penetrate the capital city’s already substantial fortifications ahead of the Games. On Monday, the Beijing Center for Disease Control and Prevention called on residents who had traveled to areas with recent flare-ups to report themselves to the authorities. That would include anyone who has been in or passed through Tianjin since Dec. 9.
