    The most explosive news these days is the new crown epidemic in Beijing
    .
    After nearly two months of no diagnosis, several local diagnoses suddenly appeared.
    Today, the official announcement of 45 positive persons
    .
    The situation suddenly became tense
    .
    As the epidemiology of the confirmed case points to the chilled salmon stall in the Xinfadi beef and mutton wholesale hall, the building is temporarily closed, Jingshen Seafood is also closed, and major supermarkets have urgently removed salmon from the shelves, so the following picture Figure
    .
    This picture may be a joke, but it is true that some cheap salmon on the market is faked with rainbow trout
    .
    If you remember the salmon group logo, it won’t be surprising
    .

    Next, I will mainly talk about your questions about salmon
    .
    1.
    How can salmon carry the virus?
    Salmon "carrying" coronavirus and bats "carrying" coronavirus are two different things
    .
    The "carrying" of salmon is precisely contaminated and contaminated
    .
    The "carry" of bats is a host that can symbiotically
    .
    At present, the known hosts of coronaviruses are all mammals, and the possibility of salmon carrying coronaviruses is almost zero
    .
    The possibility of salmon being infected with the virus is very high, but it is not absolute
    .
    The current news is that a virus has been detected on the cutting board.
    It depends on whether the cutting board has cut anything other than salmon.
    It is necessary to exclude other things that indirectly contaminate the salmon
    .

    2.
    Where does the virus on salmon come from?
    Assuming that the virus is indeed brought by salmon, and the reports currently seen say that the virus sequence is confirmed to be a European strain, then a reasonable inference is that the salmon from Europe was contaminated in Europe
    .
    Whether it is contaminating the salmon or contaminating the foam box or the crushed ice in it is still difficult to confirm
    .
    But it can be inferred that among the people involved in the fishing, processing, and transportation processes are infected
    .
    The European countries that export salmon to China are mainly Norway and Denmark.
    It is difficult to judge who it is for the time being, but we Chinese are reasonable and will not let them lose money
    .
    3.
    How does the virus on salmon infect people?
    This question is a bit weird.
    More than 50 people have been diagnosed and positive.
    You said it was transmitted by salmon.
    I don't quite believe it
    .
    Coronavirus cannot replicate outside the body of warm-blooded animals.
    To infect more than 50 people, the amount of the virus should be a lot
    .
    Therefore, the salmon may be transmitted to humans at first, but the possibility of human-to-human transmission is relatively high
    .
    Everyone is very concerned about the channels through which salmon is passed to people, because it involves the question of whether salmon can be eaten
    .
    In my opinion, the most likely transmission is through mucosal contact, such as touching contaminated chilled salmon, rubbing your eyes or picking your nose without washing your hands, or contaminating the stall and surrounding environment through salmon, and then spreading through contact
    .

    4.
    Can salmon still be eaten?
    So far, there is no evidence that the new crown is spread directly through eating and drinking, and it is mainly spread by contact
    .
    If it is cooked food, of course it will not be a problem.
    If it is raw food, the risk is a little bit higher, because the virus has a little more chance of contacting the mucous membrane
    .

    The survival time of the new coronavirus on the surface of the object varies from a few hours to a few days.
    The chilled salmon is transported by air and has low temperature environmental protection, so it is theoretically possible to survive
    .
    Although this probability is not high, considering that once an epidemic is caused, the cost of prevention and control is extremely high, so the country may control such products in the near future
    .

    For individuals, the probability of contracting the new crown through raw salmon is extremely low, but this is a completely unnecessary risk
    .
    To be safe, I suggest that you refrain from eating raw salmon and other imported fresh foods, and wait for the results of official investigations in these two days to become clear before making a decision
    .

    When frying, it should be fine if it is half a lifetime inside, because it is contaminated on the surface
    .
    If you insist on eating raw, at least the surface should be rinsed with running water
    .

    5.
    How to protect yourself?
    First of all, some businesses have labeled "Non-Xinfadi" and "Non-Beijing", which is very shameless
    .
    China's local farmed salmon has not yet become a climate, and the market is mainly dependent on imports
    .
    This kind of low-probability infection incident is not because the newly-occurring area is not doing well or Beijing's prevention and control is not good, but it depends on luck
    .
    The cost of zero risk management and control is unacceptable to everyone
    .
    Secondly, rainbow trout don't want to "turn over the serfs and sing.
    " The risk of infection of parasites from raw rainbow trout is far greater than the risk of infection of new crowns by eating salmon
    .
    There are indeed rainbow trout fake salmon on the market.
    It is said that this time they all voluntarily admitted that they are rainbow trout
    .
    I suggest you eat it cooked
    .
    For ordinary consumers, the main emphasis is on buying and wearing masks when going out, washing hands at home, and washing hands before and after preparing food, and try not to touch their eyes, nose, and mouth with dirty hands
    .
    Be vigilant and don't let everything go
    .

    Digression
    1.
    How many people are "infected" this time
    Unfortunately, the data is often the part of the iceberg above the water
    .
    Considering that the incubation period of the new crown can be 14 days, the incubation period can still be contagious, and considering the huge flow of people in the new place and a large number of positive environmental samples, the actual number of people should be more than announced
    .
    (It is not a concealment, but not knowing or realizing it) The currently announced positive person is asymptomatic, but it is not an "asymptomatic infected person"
    .
    It is expected that after epidemiological follow-up and expanded investigation, the data will almost certainly increase, and everyone is mentally prepared
    .
    This time, Beijing’s reaction speed is much faster than that of Wuhan, and the effect should be much better, but it still needs to be observed for about 2 weeks before it is truly clear
    .
    2.
    Why is the seafood market?
    Although salmon is suspected for this traceability, it is essentially just a backhand
    .
    There are more places where infected people can contaminate, such as door handles, elevator buttons, etc.
    , but this time it happened to be salmon
    .
    Of course, Huanan Seafood, Xinfadi Seafood, and Jingshen Seafood may not be entirely coincidental
    .
    What these markets have in common is that they are dark and humid, and have conditions such as refrigeration and freezing, which are conducive to the survival of the virus
    .
    The recent new case in Hong Kong is also the worker responsible for handling imported refrigerated food at the dock, so it seems that this place must be highly vigilant
    .
    In addition, the distribution of goods and personnel in the wholesale market is conducive to the spread of the virus
    .
    It was originally a dense intersection of trajectories, so it is easier to be identified when tracking the trajectory of an infected person
    .
    For a super-large city like Beijing, the wholesale market is indispensable to guarantee the supply of people's livelihood, but how to manage them during the epidemic is indeed a problem
    .
    There are still many doubts and unsolved mysteries in the Beijing epidemic.
    The official investigation is still underway.
    We look forward to more data and evidence so that we can learn more about this cunning enemy
    .
