China Disease Control Expert: Cold chain introduction possibility exists in South China seafood market epidemic

China News Service, Beijing, August 30 (Reporter Li Chun) In a recent interview with China News Service and other media in Beijing, Ma Huilai, director of the China Field Epidemiology Training Program of the China Centers for Disease Control and Prevention, said that it will happen in Wuhan Huanan Seafood in 2020.
The new crown pneumonia epidemic in the market may introduce viruses from cold chain products
.

According to the Jockey Club, in 2020, China will quickly block the local spread of the new crown epidemic with Wuhan as the main battlefield.
After winning the decisive victory in the defense war between Wuhan and Hubei, it will adopt the prevention and control strategy of "external defense input and internal defense rebound".
, And achieved very good results
.

"But in June and July last year, clusters of new crown pneumonia occurred in Beijing Xinfadi Market and Dalian Seafood Company
.

Ma Huilai pointed out that in order to find out the source of these two local epidemics, the country, province, and city set up special classes to jointly carry out in-depth traceability investigations
.

"Comprehensive evidence from multiple traceability investigations has confirmed that the virus was imported into China through the cold chain from other countries or regions outside the country
.

She also introduced that in the new crown epidemic that occurred in Qingdao in October last year, the traceability investigation not only once again proved that the source of the epidemic was also imported through overseas cold chains, but also the experts from the Chinese Centers for Disease Control and Prevention’s Virus Disease Institute for the first time from the outer packaging of cold chain products.
The live new coronavirus was successfully isolated in Shanghai, which has become a direct evidence of the cold-chain spread of the new coronavirus
.

Since then, the traceability investigation results of several local epidemics that have occurred in many parts of China have repeatedly confirmed that the new crown virus can be spread over long distances through cold chain transportation, "and once it is introduced into special places such as seafood sales markets or aquatic product processing companies, Can cause an outbreak of a local epidemic"
.

In addition, in the first half of 2020, at least 30 large meat factories, slaughterhouses, seafood processing plants, etc.
, distributed in many countries around the world, have experienced the new crown pneumonia epidemic, and the virus may be transported through the imported cold chain, causing infection and spreading.
