Beijing sends impeach of origin of virus of ground seafood market newly, expert: 3 article fish cann

Author Wu Yiting head hair at division of newspaper of Shanghai science and technology, Shanghai assist

Recently, area of Beijing abundant stage sends ground seafood market newly to break out epidemic situation, appeared a large number of native land case of illness. Detected in the chopping board that relevant section imports 3 article fish from cut new coronal virus, where is the fountainhead that this epidemic situation breaks out? We should be adopted why to plant in the light of measure, the reporter interviewed the relevant expert of Shanghai.

Cold-blooded animal is impossible to be affected

When Wen Yumei of academician of professor of college of medicine of Fudan University Shanghai, Chinese Academy of Engineering is accepting a reporter to interview, denying 3 article fish is host of new coronal virus this kind of view. She expresses, coronal shape virus can live inside mammalian body only, also can infect between mammal only. 3 article fish is cold-blooded animal, and the life is in deep-sea in, they contract new coronal virus impossibly.

The key that Wen Yumei pays close attention to is in bear the weight of a large number of ice cube of 3 article fish (ice bag) on. She tells a reporter, most virus is afraid that heat is not afraid of cold, high temperature falls to be exterminated easily, but fall in refrigerant environment, they can live for a long time. She very before the water in suspecting ice cube is freezing, had been polluted by coronal shape virus, because foreign epidemic situation is very serious, it is not strange that water is polluted. In addition, farming the sewage in secondary market is polluted possibly also by virus, be worth to sample detect. Detect to the gas collosol of these markets also conduce to block breaking infect a source.

Ginger of professor of epidemiology of communal and wholesome institute celebrates Fudan University 5 think, if virus comes over from cold chain, so from catch, a few treatment, carriage segment are polluted possibly, but these guessing still need to have evidential evidence. Batch catchs and importing fish is machined, returning those who need an answer is the pollution that is a fish after all, still be the pollution of a batch of fish. The briny environment that never has reported 3 article fish grows has coronal shape virus to exist.

Cold chain detects technology and alexipharmic technology urgently research and development

Look in Wen Yumei, of this Beijing epidemic situation eruptive exposed answer of go back to work the flaw that the cold chain link of postpartum existence detects, but the capacity that the national defence in also was being revealed controls information about and appraisal of an epidemic, those who answer efficiency is tall, be worth to praise. Epidemic prevention personnel can undertake drifting air quickly, master mobile course of the patient, final Suo Dingxin sends ground seafood market, undertake large-scale nucleic acid detects quickly, control information about and appraisal of an epidemic effectively spread.

"What need researcher attention at present is new coronal virus the specific time that survives in water, and the specific time that can survive below refrigerant environment, we if why this detect in cold chain link new coronal virus? How to undertake alexipharmic the job? If discover new coronal virus,be in in cold chain, if why are this handled? These need a researcher to study as soon as possible, give out data, put forward to answer a method effectively! " Wen Yumei says.

Wen Yumei tells the public, the surviving time of new coronal virus below normal temperature is limited, because this needs to notice to import cold chain food only, do not need repulsion to import normal temperature food.

Specific origin awaits final result drifting air even

Jiang Qing 5 think to decide now the specific fountainhead of virus, even is early still, although virus is in the new hair ground of abundant stage area,seafood market is discovered, but virus is discovered on the chopping board of seafood market, the virus on chopping board after all from why and come? If be,come from inside product of 3 article fish, the issue that needs an answer is it is to come from inside body of 3 article fish after all still be body watch, on the packing bag that still comes from carriage process. The area that Beijing sends ground seafood market newly is very large, density of stream of people is very big, because do not have the contact of the person that the symptom is affected,also cannot eliminate, bring about new coronal virus appears on chopping board.

"Investigation works and detect the job is very complex, workload is very big also, the time talent with particular need decides the specific origin of the virus in this epidemic situation, we still need to await a disease to control the epidemiology findings that the branch gives out. " Jiang Qing 5 say.
