Overpacking can cause infection?! Expert: It's more spread

According to the official website of the Chinese Center for Disease Control and Prevention, during the investigation of the origin of the outbreak of Qingdao Xinguan pneumonia, positive samples of imported frozen cod carried by workers were tested positive for the virus.
this is the first time in the world in the cold chain food packaging isolated to the new coronavirus, and confirmed that exposure to the new coronavirus contamination of the outer packaging can lead to infection.
cold chain items become a new virus carrier this time from Qingdao cold chain food packaging isolated live virus, is the first time outside the laboratory confirmed in the cold chain transport under special conditions of the new crown virus can survive on the packaging of items for a long time, suggesting that the new crown virus cold chain items as a carrier with long-distance cross-border input possibilities.
under certain environmental conditions, viruses that survive on the surface of items can cause infection in susceptible contacts without effective protection, and the population at risk of infection is mainly cold chain article practitioners.
this finding suggests that while preventing the importation of infected people from abroad, we should pay attention to the risk of entering the virus with cold-chain items contaminated with the virus outside the country.
In an interview with the Health Times, Dr. Lin Yuliang, director of the Infection Department of the Third Hospital affiliated with Sun Yat-sen University, explained, "In the past, the outer packaging detected a viral nucleic acid, equivalent to the 'wreckage' of the virus, the live virus is more contabable than the virus 'wreckage', not a live virus, it is difficult to bind to the cell's recipients, so it is difficult to invade the human body."
" cross-border express need to pay attention to the autumn and winter festival of the outbreak prevention and control need to focus on imported cold chain food and cross-border express? Lin said, not only in autumn and winter, each season should pay attention to strictly guard against international logistics, because international logistics express items in a sealed state, will not be exposed to sunlight, ultraviolet light and other external environment, can survive longer, especially cold chain food, because the cold chain itself in the frozen environment, in a low temperature situation, so every season to pay attention to.
Lin pointed out that the survival of the virus is related to temperature, humidity, but not the main factors, but the virus in the cold chain of this low temperature environment, survival time is indeed longer.
how long it will take to survive in a cold chain environment, and there is no accurate data for the time being.
, the focus of China's new crown epidemic prevention and control has shifted from "people prevention" to "people and prevention".
September 7, Zhejiang Province, the new coronavirus pneumonia epidemic prevention and control leading group office pointed out that after May 1, 2020 imports of incremental cold-chain food, must be on the packaging of its products on the "cold-chain food traceability code."
September 28, the Beijing Municipal Bureau of Commerce informed the relevant import and export enterprises to strengthen the prevention and control of overseas sources, take the initiative to avoid the import of cold-chain food from areas with severe outbreaks, take effective measures to do a good job of imported food alternatives.
Lin Yuliang reminded that we should try to avoid Haitao, buy goods in areas where the situation of foreign outbreaks is severe.
Through e-commerce, micro-commerce and other channels to buy fresh products, express packaging such as unsterilized do not bring into the room, contact with the outer packaging and fresh food should wash their hands in time, avoid touching the mouth, nose and eyes and other places.
addition, the food is cooked through to ensure food safety.
cold chain items still eat? According to the cdc news: China's market circulation of cold chain food by the new coronavirus pollution risk is very low.
recently, the relevant departments of our country carried out a new coronavirus nucleic acid sampling of cold chain food.
As of September 15, 24 provinces across the country reported 2.98 million test results, including 670,000 cold chain food and packaging samples, 1.24 million samples of employees, 1.07 million environmental samples, only 22 food and packaging tested positive for new coronavirus nucleic acid, viral nucleic acid load is low, has not been isolated to live virus.
existing research and prevention and control practices show that neo-coronary pneumonia is not a food-based disease and no infections caused by food intake have been detected.
, no cases of consumers infected by exposure to contaminated cold-chain sea products have been detected, and the risk of infection between Chinese consumers is extremely low.
route of transmission of the new coronavirus is still through respiratory droplets and close contact.
same time, China's relevant departments have increased the import of cold chain food new crown virus monitoring, disinfection and other measures, the general public pay attention to keep clean, cooked separate, can normally buy and eat imported fresh.
, the risk of infection from exposure to or consumption of cold-chain foods by the general public is low.
if you're really worried, what do you do? Ordinary people suggest that such a virus that survives under certain conditions on items contaminated with the virus may lead to infection of susceptible contacts without effective protection, mainly in the relevant industries.
If it is ordinary people, you can and relevant practitioners, to avoid direct skin contact may be contaminated cold chain products, contact with cold chain products after not taking off the clothes that may be contaminated, and wash hands before disinfection do not touch the mouth and nose, and then immediately wash hands disinfection, regular nucleic acid screening.
addition, heating is the best treatment, in addition to preventing new crowns, but also to avoid such as E. coli, salmonella, Lester bacteria, parasites and other pollution risks.
