(Fight against new coronary pneumonia) How to prevent the spread of new coronary cases in many places in China?
China News Service, Beijing, December 30 (Li Jingze, Guo Chaokai) With the successive emergence of new confirmed local cases in Beijing, Liaoning, Sichuan, Zhejiang and elsewhere, the sporadic cases have become another test in the struggle of China against the new corona pneumonia epidemic at the end of the year.
There is a day before New Years Day, and the Lunar New Year is only 42 days away. During these two important festivals, will people’s travels and gatherings be affected by sporadic cases? Experts interviewed by reporters from the China News Agency believe that although we have achieved significant results in the fight against the epidemic, the confirmed cases spread in many places still remind the prevention and control of the epidemic to be cautious and more cautious during the two festivals.

Can you eat imported fresh food?
In recent years, the standard of living of Chinese people has improved and imported fresh food has been placed at many family parties or on the daily dining tables. From the outbreak in Beijing’s New Farmers Market in June this year to recent sporadic cases involving cold chain foods in Dalian, Beijing and elsewhere, imported cold chain foods have “intimidated the public.”
This is the concept of “environmental transmission of the new corona virus”, also known as “material transmission”. Usually refers to items contaminated by viruses and infections caused by human contact. In response, Zhong Nanshan, an academic at the Chinese Academy of Engineering and director of the National Center for Research in Clinical Medicine of Respiratory Diseases, told the media: “If the substance is infected, what concentration will be contagious? How to get it? How to kill? These are all scientific problems that we must solve. ”
“It is true that imported frozen foods are still edible.” Feng Zijian, deputy director of the China Center for Disease Control and Prevention, said in an interview with the China News Agency that all localities have disinfected imported frozen food in accordance with national requirements, which can effectively reduce the risk. public display. Also, in general, the probability of frozen food becoming contaminated is not high.
Feng Zijian revealed that there are no reports of consumers exposed to imported frozen food and external packaging of the novel coronavirus in China, but reminded the public to pay more attention when buying and cooking frozen food. For example, wash your hands before handling food, separate raw from cooked ingredients, and cook well.
Can’t go home or travel after saving energy?
Recently, several localities have successively introduced relevant measures for the prevention and control of the epidemic during the double festival period, promoting non-essential travel, non-travel and off-peak hours. Elementary and secondary schools are also rolling out early vacations. Faced with the increasingly tense situation of prevention and control, many people have had difficulties between walking and not leaving. The hidden concern lies in the unknown risks along the way, that is, we do not know when and where we will find a potential diagnosis. Asymptomatic patients or infections.
“Currently, in society at large, the risk of transmission in China is very low.” Feng Zijian analyzed that we found sporadic cases in a timely manner. Large-scale isolation detection and regional prevention and control measures can effectively control the spread. The greatest dissemination of the case.
Wang Daming, a researcher at the Suzhou Institute of Biomedical Engineering and Technology, Chinese Academy of Sciences, noted from the perspective of transmission probability that there are currently dozens of sporadic cases in China, and in China’s 1.4 billion population: ” As long as prevention and control are done well, the virus has lost the possibility of a large-scale outbreak. Sex. ”
However, the low risk of infection does not mean that prevention and control can be relaxed. Zhong Nanshan publicly stated recently that more attention should be paid to traveling now, and that going abroad or to medium-risk areas in China is not encouraged.
The current new corona pneumonia epidemic continues to circulate around the world and the low temperature makes the virus live longer and increases the likelihood of infection. Feng Zijian emphasized that it is still necessary to wear masks, wash hands frequently, and maintain social distancing when traveling on double festivals. These three protective principles will likely remain in place for a long time to come.
Can’t meet after saving energy?
In the Spring Festival of 2020, the slogans that are propagated not to visit family and friends are still in force, and the painful cries of the government cadres in the large speakers of the municipality remain in the ears. In the blink of an eye, the 2021 Spring Festival is approaching. Due to the prevention and control of the epidemic, visits to family and friends will continue to be an option of exclusion or precaution.
Feng Zijian said that before sporadic cases appeared, there had been no epidemics in many places for a long time. We have not yet been able to judge whether there is an epidemic on each specific occasion, specific group of people, and specific time. In this circumstance, no meeting and fewer meetings are undoubtedly effective measures to reduce risks.
Wang Daming noted that respiratory droplet transmission is the main route of spread of the new coronavirus. If there are potentially confirmed cases in the meeting, the risk of infection is very high. He believes that during the period of the double festival, it is necessary to understand the life trajectory of relatives and family friends as much as possible, and not go to relatively unknown local places.
When will the phenomenon of sporadic cases end in many places? Wang Daming said that this depends on the severity of the epidemic abroad, the intensity of prevention and control, and the immune status of people at low temperatures. Faced with many unknowns, what we know is to do prevention and control in detail. As Feng Zijian said, the prevention and control of the epidemic in China has taken preventive measures as a whole. Even in a relatively safe environment, we must be cautious. (End up)
