At 9:00 p.m. on February 9, the Hubei Provincial Command for Prevention and Control of the New Crown Pneumonia Epidemic held its 19th press conference, focusing on scientific research on prevention and control of the New Crown Pneumonia Epidemic. At the meeting, the Huazhong University of Science and Technology School of Public Health Vice President Xu Shunqing, on the “new coronavirus can be transmitted through aerosol transmission, fecal-oral transmission” of this recent widespread concern about the topic, carried out a detailed introduction. Aerosol transmission is not airborne, open window infection is much lower than the probability of winning the jackpot on the recent netizens generally concerned about what is aerosol transmission? Is there any case of aerosol infection in Hubei Province at present? What are the main ways of spreading the virus? Can residents open windows to change the air? How to effectively prevent the spread of aerosols? Huazhong University of Science and Technology, School of Public Health, vice president Xu Shunqing made the following explanation and reminder: there is no direct evidence that aerosols can cause the spread, but we are worried about is understandable, the current aerosol transmission should be considered mainly in some special environments, such as closed narrow space, there are reports that there are operating rooms, a one-time release of a large number of viruses, which may produce this kind of situation aerosol dissemination, there is This is possible. But we may misunderstand the aerosol transmission, and we think that airborne confusion, we think that the air in Wuhan is full of aerosols, everywhere in the air there are viruses, Wuhan air is full of viruses, we are very fearful, which is completely unnecessary. In fact, aerosol is some very small particles, even to zero point a few microns, including objects and solid particles to form aerosols, virus particles can not exist in the air for a long time. Normally we can prevent the spread of aerosols by wearing masks. So I don’t think we should worry about aerosols, I think the probability of spreading aerosols is very low, like opening windows, normal indoor ventilation, and the probability of spreading aerosols through an open window is much lower than that of winning the Grand Prize, which is something we should be aware of. The so-called aerosol transmission may be a possibility in some specific cases, relatively single, not that the general airborne transmission of the virus. There may be a risk of fecal-oral transmission, but even if there is, it is controllable. Don’t worry, washing your hands before and after meals is an effective measure for fecal-oral transmission of the new coronavirus. What kind of preventive measures should be taken by urban residents and rural community residents, Xu Shunqing made the following explanation: regarding fecal-oral transmission, the source of this matter is because the virus was detected in the patient’s feces, the test is to use nucleic acid, PCR test, did not directly detect the virus particles, but detected, indicating that there may be such a risk, there is such a concern. As a reminder, novel coronavirus is a respiratory infection, and the most difficult respiratory route for it to deal with is respiratory transmission. If it were not for respiratory transmission, we would have had the disease under control, and because of respiratory transmission, we are still in the fight today. In case of digestive and fecal-oral transmission, it is also relatively easy to control, as long as everyone pays attention to personal hygiene, and wash their hands before and after meals, this transmission route is relatively easy to cut off. The most difficult thing to deal with is respiratory and contact transmission. In rural areas, everyone should strengthen personal hygiene, and also strengthen fecal management, so that it will not spread easily. Regarding fecal-oral transmission, even if there is such a route, we think it is completely controllable, and this route is not the biggest reason for concern.
