The red alert lit on China with new focuses of coronavirus, mainly caused by the spread of variant delta. Touted as one of the main epicenters of the crisis, the city of Nanjing, the country’s former capital, was surrounded by military barriers — the objective is to test all people who want to enter the urban complex. At the same time, the population is being advised not to travel. All flights were suspended.
The number of cases began to increase in mid-July, when several workers at the local airport tested positive for covid. In the past ten days, more than 170 people have been diagnosed with the virus. Just last Wednesday, 28, the city registered 49 new cases. A mapping of the zones with the highest incidence of cases allowed the classification into four areas of high risk for covid and 42 of medium risk, according to the municipal central for the prevention and control of the coronavirus.
The strategy to control transmission of the delta variant, considered more contagious than the original strains, has been mass testing, strict rules of social isolation, speeding up the vaccination campaign and wearing a mask.
Case tracking is another important pillar of this approach. According to local authorities, at least part of the newly infected people attended a mega show on July 22 in Zhangjiajie, in which the rules of social distancing were not followed. A good part of the audience, made up of 2,000 people, passed through Nanjing airport.
Nanjing, with 9.3 million inhabitants, is one of the main industrial and transport hubs in the country. It is also home to several universities and important research centers. The city also draws attention from a historical point of view, having been the capital of local empires four times. There are still remnants of the ancient palace of the Ming dynasty and the tombs of its former emperors.
