(Fighting New Coronary Pneumonia) Where is the prevention and control of winter epidemics that have been spreading in multiple places?
China News Service, Beijing, November 23 (Reporter Li Yanan) After the local epidemic in Xinjiang achieved zero new cases in early November, more than ten sporadic cases occurred in Shanghai, Tianjin, Anhui, and Inner Mongolia.
Why does the sporadic "epidemic" fire continue, and what are the main problems facing the current epidemic prevention and control?

Faced with the severe international epidemic prevention and control situation, the importance of "human and material" co-prevention of foreign import has been repeatedly mentioned by Chinese officials, experts and scholars.
The Tianjin CDC recently sequenced and analyzed the respiratory tract samples of multiple cases in the city. The results showed that the virus sequence was consistent with the virus sequence of an asymptomatic infection in the local area. The asymptomatic infection was a porter in the Yangbei Logistics Park in Binhai New Area. The virus belongs to the European family branch I of the L genotype.
Therefore, it is basically determined that many cases are related to imported cold chain food.
In fact, the former Beijing, Dalian, and Qingdao epidemics have all been exposed to cold chains, and relevant departments have already gradually strengthened the prevention and control of the cold chain.
A few days ago, Fujian, Hubei, Gansu, Shandong and other places exposed the detection of the new crown virus from the cold chain environment, and all regions have stepped up the prevention and control of cold chain food from the purchase to the consumer terminal.
However, to do a good job in the prevention and control of the "material-to-person" epidemic, it is not just the cold chain that needs attention.
The Shanghai Centers for Disease Control and Prevention revealed on the 23rd that a locally confirmed case and another confirmed case in Anhui were both workers who were engaged in cargo handling at Shanghai Pudong Airport. The two had entered and cleaned up one from North America on the same day. The aviation container after returning to Shanghai.
The exposure time to the time of onset coincided with the incubation period. At the same time, the genes of the two cases were highly homologous and highly similar to the epidemic strains in North America, suggesting that the source of infection was imported from abroad.
"After entering the winter, all international cargo environments are similar to the cold chain in summer, and the low temperature in winter causes the'non-cold chain' to tend to the'cold chain' effect." Wu Zunyou, chief epidemiologist of the Chinese Center for Disease Control and Prevention, was interviewed Shi pointed out that the recent international epidemic is serious, the risk of foreign goods being contaminated is high, and the temperature in winter is low, the virus will survive on the surface of the goods for a longer time, and the risk of infection when exposed to these goods will increase.
Therefore, imported non-cold chain goods should also be managed in accordance with cold chain standards, and sampling and testing of goods and regular personnel screening should be adhered to.
A variety of respiratory infectious diseases are high in winter. As the first line of defense to stop the spread of the epidemic, the layout of fever clinics and fever sentinel clinics in various places is also crucial.
Recently, a case in Shanghai was diagnosed after the hospital’s fever clinic. The hospital’s nosocomial infection prevention and control is in place, follow-up investigations and test results are released quickly, the local epidemic prevention and control and citizens’ lives are in order. A series of operations are praised by netizens as calm and calm Shanghai sample".
Zhang Wenhong, director of the Department of Infectious Diseases at Huashan Hospital Affiliated to Fudan University in Shanghai, recently emphasized on multiple occasions that to get ahead of the virus, the starting speed must be fast, and the starting line is at the fever clinics and fever outpatient clinics of medical institutions in various cities.
The first cases of multiple epidemics, including Beijing Xinfadi, Dalian, Shanghai Pudong and other places, were found in fever clinics.
"The first thing Shanghai did in the first half of this year was to expand the layout of fever clinics and fever sentinel clinics in Shanghai." Zhang Wenhong said that a city has gridded fever clinics and established sensitive fever clinics. The system can find the first patient in time.
Regarding the future situation of the epidemic in China, officials have repeatedly pointed out in recent days that the epidemic will be sporadic in winter, and clusters of epidemics may occur in some areas.
In the future, we will strengthen emergency response to clustered epidemics and prevent and control epidemics around the Spring Festival holiday.
When talking about the "new situation of anti-epidemic after multiple local cases in winter", Zhang Wenhong said that from the perspective of prevention and control effects, the current epidemic is within controllable range, and there are no continuous second-generation cases in the community.
The arduous and long-term nature of future epidemic prevention challenges may exceed most people's imagination.
The most cost-effective anti-epidemic strategy should be sought based on the specific conditions of each region.
The more current epidemic prevention strategies are explored, the greater the confidence that the epidemic will be fully controlled in the future and the normalization of social production and life will be maintained.
