According to on June 14 message of Beijing press conference, beijing appeared continuously recently diagnose case of illness and nucleic acid detect positive case, with new hair ground terminal market is associated, beijing already entered unusual times. This virus is on chopping block of 3 article fish discovery, and fish of this 3 article comes from market of Beijing deep seafood. Beijing disease accuses central new coronal when pneumonic epidemic situation prevents Yang Peng of the member that accuse an expert to comprise's researcher to accept CCTV to interview, express, beijing sends the virus of the ground newly to trace to the source to still be in further investigation.
Yang Peng explanation says, measure foreword discovery through complete gene group, virus comes from European direction, preliminary decide with the input the gender is concerned. But how virus comes after all still cannot decide, the sea product that is pollution likely or flesh kind, or the person that enters the market has transmission through secretion.
"Wholesale " , " seafood " , these keywords in what go up to break out with the epidemic situation before this somehow market of the seafood austral Wuhan China is contacted together. Different is, in although this virus still is in,tracing to the source, but the likelihood that already led a platoon to carry virus besides itself of 3 article fish probably, estimating more is to come from carry wait for other link.
Current, the virus origin of market of the seafood austral Wuhan China still is in date from, but national disease accuses central director Gao Fu to express when accepting media to interview, the animal that gathers before this gives virus without check in the specimen, china Nanhai fresh market or for " fall victim unit " . Come so, china the virus origin of Nanhai fresh market also appears complicated and confusing, its are true origin also becomes heat to discuss a central issue, under heavy anything that misleads people, where does virus come from after all?
01
Virus of new hair ground points to Europe
Beijing has not been had 56 days continuously add case newly. But in June 11, after diagnose of 12 days of successional and sick exemples, sequel appears to send ground correlation case newly in succession, up to on June 14, beijing accumulative total 51 case of illness, all concern with new hair ground.
On June 12, beijing adds 6 native land case newly, all have activity of terminal market of produce of new hair ground history, zhang Yuxi of terminal market president discloses new hair ground, detected in the chopping board that imports 3 article fish from cut new coronal virus, this product supply of goods comes from market of Beijing deep seafood. In the 5424 environments sample book that that day at the same time farming trade examines terminal market is big rows, new hair ground has 40 nucleic acid to detect show masculine gender; 517 from inside personnel of course of study, have mop of 45 people pharynx child electropositive.
Beijing sends the ground newly terminal market already rested at present city
However many expert expresses, 3 article fish is not the person that new coronal virus is carried.
On June 13, national Wei Jian appoint the chief scientist before disease of the member that high level expert is comprised, China accuses central epidemiology Professor Ceng Guang points out, gene measures the preliminary result of foreword to show, unlike of virus poisonous individual plant is the type of domestic popularity.
On June 14, the explanation when Yang Peng accepts CCTV to interview says, measure order through complete gene group, discovering virus come from European direction, preliminary decide with the input the gender is concerned. But how virus comes after all still cannot decide, the sea product that is pollution likely or flesh kind, the person that perhaps enters the market has transmission through secretion.
With respect to transmission way, " virus of new-style coronal shape is pneumonic plan of diagnosis and treatment (try out the 7th edition) " in point out clearly, via respiratory tract flying foam and intimate contact travel is main transmission way; Expose Yu Gaonong for long in the environment that closes relatively to spend gas collosol circumstance to fall, existence classics enrages the likelihood that sol transmits; Because be in excrement and urine and make water dissociable to new coronal virus, the gas collosol that should notice excrement and urine and make water are caused to environmental pollution or contact travel.
Before market of new hair ground has cut, 3 article fish still has catch, butcher, carry, pack wait for many link, one does not wish the epidemic of sign one's name, microbial expert expresses to 21 new health, new coronal virus may adhere to through a certain link the surface in 3 article fish, and cold chain also benefit survives at virus longer time.

Yang Peng also expresses, new hair ground is the room with one individual very big flow, have many person and article flow possibly everyday. At present case of illness is mixed detect the place that gives masculine gender basically centers in underground of hall of flesh of flocks and herds, this place on one hand personnel is more; And flesh of flocks and herds, seafood needs to store below microtherm environment, also may compare other place more the implementation that benefit survives at virus and travels.

The virus origin of complicated and confusing
Sending retroactive of virus of ground new coronal newly at the same time, because of its and Wuhan China the similar sex with eruptive epidemic situation of Nanhai fresh market, latter virus origin also causes public attention afresh. Two afore-mentioned markets all collect bigger terminal market for person discharge, also concern with seafood market.
According to Xinhua News Agency on January 26 message, chinese disease accuses central virus to be in virus of new-style coronal shape to trace to the source in research, first from Wuhan China in the 585 environments example of Nanhai fresh market, detect 33 sample contain nucleic acid of virus of new-style coronal shape, virus gives successfully in the depart in electropositive environment specimen, hint this virus originates China the wild animal that Nanhai fresh market markets.
These electropositive example distributing in the market on 22 stall and a dumpcart, among them cloth of devoir of 93.9%(31/33) positive sign is in China Nanhai fresh market on the west area. Via investigating discovery, china Nanhai delicacy is seafood market on market name, it is an integrated market however actually. Area existence wild animal trades on the west, especially 7 streets near market interior area with 8 streets, put in many wild animal to trade business shop, the electropositive specimen of this one area also compares concentration, occupy the 42.4%(14/33) of all and electropositive example. The place on put together is narrated, height suspects this epidemic situation and wild animal trade about.
Nevertheless so far, although discover virus of new-style coronal shape is come from China Nanhai fresh market, in also cannot affirming fountainhead is this market has 42 kinds of game that do business after all which kind of, still come from this market tens of, about a hundred kinds of seafood.
Press the opinion of experts, this new hair ground breaks out in incident, big probability of 3 article fish is not host of new coronal virus. And on May 25, national disease accuses central director Gao Fu accepting phoenix to defend inspect when interviewing, also express, market of the seafood austral Wuhan China or for fall victim unit, because animal example is medium,did not extract virus.
Gaofu expresses, oneself ever were at the beginning of January collected a few samples personally to Wuhan, among them animal example gives virus without check, but there is check to give virus in the environmental example such as sewer waste water. "The earliest we figure seafood market may be (virus fountainhead) , but look now, seafood market itself also is fall victim unit, before this virus had existed " .
Gao Fu emphasizes repeatedly, virus traces to the source the process is very complex, scientists think for a time 2003 the intermediate host of SARS virus is masked civet, but later consider to discover, masked civet is not the host intermediate, it is amplifier only, enlarged virus transmission.
