The source of this round of epidemic in Yili, Xinjiang has not been finalized, because all the confirmed cases in the local area were found by routine nucleic acid detection. All belong to asymptomatic infected people, and I don't know why they are infected with the virus. In the later investigation, three more infected people were found.
First, actively investigate and implement isolation.
After asymptomatic infected people appeared again in Yili, Xinjiang, an emergency response was launched. The active areas of infected people were strictly investigated, and a large number of close contacts were identified and observed in medical isolation. And all local residents were tested for nucleic acid and related epidemiological examination to prevent local residents from leaving Yili. The source of the epidemic is also under active investigation, but it has not yet been finalized.
Second, the source of the epidemic may be related to overseas input.
According to experts' estimation, the source of the epidemic in Yili, Xinjiang may be related to the import from abroad, because Horgos, where asymptomatic infection cases occur, is a famous customs port in Yili and the largest land port in Xinjiang. Compared with Kazakhstan, a large number of people enter and leave the country and goods are imported and exported every day. It may be that COVID-19 was brought in during the movement of people or the import of goods, resulting in virus infection, but whether he will come back like this depends on official news.
Third, epidemic prevention and control cannot be relaxed.
Although the epidemic situation in China is relatively stable, the prevention and control of the epidemic situation cannot be relaxed. After asymptomatic infection appeared in Yili, Xinjiang, the response was extremely rapid. Even if the flight from Yili is cancelled and the local railway and highway transportation is stopped, let those tourists who travel to Yili wait in the hotel, carry out nucleic acid testing and make sure it is safe before leaving. As ordinary residents, we should also take preventive measures against epidemic situation, disinfect frequently, wear masks, and don't go to middle and high-risk areas.
