In the last 30 days, China has accumulated 98 newly confirmed local cases, which is 7.5 times more than in the previous 30 days, showing the coexistence of transmission characteristics of “object to person” and “from person to person”. So far, more than 58.9 million people around the world have been infected with the new corona virus. The data shows that China has a total of 98 recently confirmed local cases in the last 30 days, which is 7.5 times more than in the previous 30 days. Winter is coming, will the epidemic return? On November 25, the press conference of the Joint Prevention and Control Mechanism of the State Council responded to public concerns.
The characteristics of communication coexist “from object to person” and “from person to person”
Today, the country of origin of cases imported abroad continues to increase and the risk of transmission continues to increase. According to Mi Feng, spokesperson for the National Health Commission, the spread of the epidemic shows the coexistence of “from one object to another” and “from one person to another.” Recently, the positive nucleic acid detection rate of imported foods from the cold chain has increased significantly, affecting more provinces. The products involved range from seafood to meat products from livestock and poultry. The scope of imported virus-contaminated materials has expanded from cold chain foods to packaging.
In this regard, Li Ning, deputy director of the National Center for Risk Assessment for Food Safety, said that, on the one hand, it is because many countries abroad are currently in a period of high incidence of corona pneumonia new. The surface of various objects, including food and its outer packaging, can be contaminated by the new corona virus. The new coronavirus can survive for a long time in low temperatures, so imported cold chain food and its outer packaging can become carriers for long-distance transport of new coronaviruses across borders. On the other hand, in accordance with the requirements of the joint prevention and control mechanism of the State Council, several departments and localities have recently increased the detection and sampling of imported food from the cold chain and its external packaging for the new nucleic acid of the coronavirus. With the increase in the frequency, frequency and coverage of detection, positive The probability also increases.
“In general, the positive rate is relatively low. So far, the positive rate of random inspections across the country is 0.48 per 10,000 and is mainly concentrated on food packaging,” Li Ning said, showing that China is strengthening the physical defense. The measures taken are effective and reduce the risk of transmission.
Regarding cold chain food disinfection, Zhang Liubo, chief disinfection expert at the China Center for Disease Control and Prevention and director of the Center for Infection Control and Disinfection of the Environmental Institute, said: “Recently, we have found that cold chain food packaging is closely related to the epidemic. In October, the mechanism promptly issued the technical document of the “Technical Guidelines for the Prevention, Control and Disinfection of the New Coronavirus in the Process of Production and Operation of Food in the Cold Chain” (hereinafter, the “Guide”). There is no problem in sanitizing the surface of cold chain food packaging at low temperature at room temperature. Yes, but if we want to sanitize the surface of food in low-temperature cold storage, we are intensifying research on related technologies and methods, hoping to produce results as soon as possible. “
The director of the Office of Food Safety of Import and Export of the General Administration of Customs, Bi Kexin, indicated that since the launch of the “Guide” at 24:00 on November 24, the preventive disinfection of food packaging imported cold chain in ports has accumulated more than 1.6 million pieces, weighing more than 30,000 tons, and the scope of disinfection Including outer packaging, containers, air pallets, trucks with land transport box and bulk fishing vessels of imported food from the cold chain. The General Administration of Customs will continue to ensure the safety of cold chain foods exported to China in accordance with preventive and comprehensive disinfection requirements.
People in specific types of work need to strengthen protection
Recently, imported cold chain food handlers have been infected with new coronary pneumonia in Dalian, Qingdao and Tianjin. Li Ning said this shows that under certain environmental conditions, if protection is not in place, people in certain types of work can become infected with the new corona virus due to frequent contact with elements of the cold chain contaminated by the new corona virus.
Therefore, to do a good job in physical and air defense, the “Guide” requires that practitioners of the food cold chain do a good job of prevention and control in handling, production, processing, transportation, sales and catering. . Li Ning explained that people with special jobs should wear work clothes and hats, disposable medical masks, gloves and goggles, and face shields when necessary and should avoid direct skin contact with cold chains throughout the handling process. . Wash and disinfect the surface of the item immediately after handling. Never touch your mouth, eyes, and nose before removing work clothes and washing your hands. At the same time, regular nucleic acid screening for physicians should be strengthened.
Regarding the public’s concern about whether imported frozen food is safe to eat, Zhang Liubo replied that attention should be paid to some aspects: the surface of the food packaging should be disinfected to avoid splashing and contamination of the surrounding environment. Good hand hygiene, “It is better to eat cooked food during the epidemic.”
Confident to prevent the epidemic from returning
With the global epidemic worsening, will the epidemic return to our country? In this regard, Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention, said that some sporadic cases in China are also common phenomena in standardized prevention and control. It is very difficult to avoid completely, but it can be controlled through a number of measures. The occurrence of a sporadic collective event.
He noted that these measures may include: implementing standardized prevention and control measures; increase monitoring and testing; once sporadic cases exist, quickly take steps to control the epidemic to a minimum; with the identification of high-risk groups. The application of emergency vaccines can also prevent similar phenomena.
Summing up the experience of the last 11 months, we hope to prevent a recurrence of the epidemic and prevent the occurrence of a serious epidemic like the one in early 2020. Wu Zunyou pointed out that to achieve this, we must apply scientific prevention and control measures. In short, scientific prevention and control. Implement policies with precision, focus on efforts, highlight key points, and keep the epidemic to a minimum the first time.
Winter and spring are the seasons of high incidence of infectious diseases. Wu Zunyou urged that everyone should start for themselves, strictly adhere to relevant regulations on epidemic prevention and control, and develop good personal hygiene habits, such as wearing masks, washing hands frequently, ventilating more, collecting less, using noodles from rice and use public chopsticks, especially Always respect personal protection in closed public places such as elevators.
