A new virus strain was detected in Sanya, and the escalation of the epidemic adopts global static management, and implements first management and then screening

From the first confirmed case in Sanya on August 1 to yesterday, the city has accumulated 375 confirmed cases and 62 asymptomatic infections, becoming the center of the new epidemic storm. The epidemic presents some new features and requires special treatment and prevention and control.

First of all, the first case of a new variant of Omicron in the country, BA.5.1.3, was detected in the infection cases in Sanya. This variant has not been detected in China before, indicating that the epidemic may be The possibility of overseas importation is relatively high, but unlike the imported cases in other cities, other cities are mainly people returning home by plane, while the case in Sanya is very likely to be transmitted when local fishermen and foreign fishermen trade fish, so it is difficult to track. , the transmission chain is complex, the radiation surface is wider, and a wider range of control and screening is required.

Secondly, Sanya is a tourist city with a very large population flow. After the implementation of global static management, the stranded tourists in the local area are easy to walk around and look for opportunities to go out of the city when they have nowhere to arrange. It is possible for some infected tourists to carry the virus to other cities, so it is necessary to arrange the isolation of tourists as much as possible to properly solve the worries of tourists.

Third, the nucleic acid testing capacity is relatively tight. Currently, there are 12 nucleic acid testing institutions in Sanya, which conduct testing 24 hours a day. The daily testing capacity can reach up to 150,000 tubes. However, the daily testing capacity is 1.5 million people, and the population of Sanya City is 1.03 million. In addition to the floating population, the testing capacity can only just meet the testing needs, which is relatively tight. Therefore, the strategy of screening after control is implemented. With the intensification of nucleic acid testing in the later stage, new adjustments may be made to prevention and control strategies.

The particularity of Sanya makes the epidemic control different from other cities. Not only are there many tourists, but they also communicate closely with fishermen from other countries. The epidemic is easily imported from abroad and may be projected to other areas. The later epidemic management and control brought difficulties, but with the improvement of detection capabilities, the epidemic situation is basically within the controllable range, and it is believed that dynamic clearing can be achieved soon.
