Last night, News 1 and 1 invited Wu Zunyou, chief epidemiologist at the China Center for Disease Control and Prevention, to respond to hot issues related to the outbreakWhat does it mean to find the new crown virus in the packaging of imported frozen white shrimp? Yesterday's State Council joint defense and control press conference informed that Ecuador's three enterprises produced products (mainly frozen South American white shrimp) in the process of importing into China, its container environment, cargo packaging-related samples detected positive for the new coronavirus, there is a risk of contamination by the new coronavirusWu Zunyou said the news is very important, it reminds two aspects - imported seafood to bring the virus into China is possible, this kind of introduction can cause a new outbreak, need further scientific demonstrationto tighten inspections or simply prohibit imports of imported goods, especially those from affected countries, especially those with frozen packaging and cryogenic preservationthese measures can reduce riskIf there are more sporadic cases, does it mean the outbreak is rebounding? Is there a possibility of sporadic cases in the future? Wu Zunyou believes that this is possible, but individual sporadic cases do not mean that the outbreak is not controlled or the outbreak reboundedbecause of close contacts that are missing from some surveys, or because of atypical symptomsfrom the current situation of prevention and control in Beijing, even if there are, this kind of sporadic cases are not particularly meaningful, are in the control of prevention and control, will not pose a threat to societyfound the source of this wave of outbreaks in Beijing? Wu Zunyou said it was difficult to find the source of the virusa 56-day outbreak in Beijing, which suggests the virus must have been brought in from outsidehas now started to work on two fronts, one is to bring to the new origin market items, the other is peoplefrom a human point of view, a lot of lead investigation and troubleshooting, more and more clues have been ruled out, and some new clues are being identifiedWu Zunyou, a supplementary investigation into early cases, is being implementedsupplementary survey answers two questions: some are infected, some are not infected, some are infected, some customers are not infected, some customers are not infected, the specific reason sitswhether it's a human or an item that brings the virus into see if the clues provided by the practitioners and early customers can provide new ideas and investigate praised Beijing for its global role model for prevention and control, and thanked Wu Zunyou, the "Master of the West", for saying that Beijing's response has provided a very good example for the rest of China and the world analysis has found that Beijing's response time is almost impossible to shorten each link is very compact, with almost no delay the first cases to be detected, the first to take measures, did not allow the virus to spread on a larger scale the most important thing in the prevention and control of this outbreak is early patient visits, causing concern in the medical system he said that this should be thanked the first case of the outbreak of the "West City Master", if he is infected, do not go to the doctor, will cause spread in the family, the community, so the patient's awareness, active reporting, very important is pneumonia in Kazakhstan the new crown? Kazakhstan's health ministry yesterday denied that the country had "unexplained" pneumonia with a death rate higher than the new coronavirus, saying those cases were likely to be cases of the new coronavirus , Wu Zunyou agreed: from the report statistics, from the epidemiological point of view, should be the new crown pneumonia is more likely if it is a new respiratory infection, it is less likely to occur in the summer, even if the new crown pneumonia it first occurs in winter, like the original SARS also occurred in winter, as well as influenza, avian influenza , in the context of the global new coronapneumonia epidemic, Kazakhstan itself is also a country that is heavily affected by the new coronavirus in terms of fatality rates, but also within the range of new crown pneumonia , taking into account Kazakhstan's medical capacity, especially the ability to test and test, the pneumonia is more likely to be the new crown pneumonia new crown virus has a large rheogenest virus around the world? Wu Zunyou said that the main structure of the new crown virus has not changed, which is very good news for vaccine research Although viruses change very little amino acids at a time, these small changes do not change the structure of the virus .
