Is it safe to unseal Wuhan? No, there are still some risks.
Recently, the number of asymptomatic infected people announced in Wuhan is also quite large. On April 7th, the number of asymptomatic infected people in China reached 137, which is not a small number. Some communities in Wuhan were cancelled due to the addition of asymptomatic infected persons and close contacts, and some communities without epidemic situation were still strictly managed. Xiao Yuan's community is like this, and he still can't go out. Will he go to work with the certificate of returning to work, buy food or buy a group? What is an asymptomatic infected person? Is to carry the virus in the body, but the body has no symptoms of discomfort. This group of people can be described as a hidden source of infection, because there are no symptoms and can only be determined by nucleic acid testing. Therefore, these potential asymptomatic infections are more dangerous than those diagnosed.
For the normal operation of Wuhan, a big city with a population of 10 million, and to ensure the life and production of Wuhan people, Wuhan has been unblocked and all walks of life have begun to resume work one after another. But is Wuhan really safe at this time? The answer is obvious. Wuhan is not safe enough now. In addition, the epidemic situation abroad is grim, and the epidemic battle is far from over. We have not yet won the final victory in fighting the epidemic.
Does the lifting of the ban in Wuhan mean the end of the domestic epidemic? number
The rapid control of this epidemic has a lot to do with summing up historical lessons. 1967, epidemic cerebrospinal meningitis broke out in China. At that time, more than 3 million people were infected and 16000 people died. This is a lesson from blood. It is precisely because of these lessons that the expert group's proposal to close the city was quickly adopted by the central government. In retrospect, it is very wise. This epidemic prevention war can be called a very beautiful victory.
From the very beginning, China was the most serious and passive situation in the world, and it suddenly turned over. At the same time, Professor Ceng Guang further stated that the closure of Wuhan does not mean the end of the epidemic. As long as the whole world does not end, China will not end. COVID-19, regardless of wealth or race, spreads indiscriminately, which also requires us to continue observation and research, strengthen the awareness of prevention and control, and improve the medical level, so as to completely defeat the virus.
Whether the risk of asymptomatic infection can be controlled is a potential risk of the outflow of unsealed personnel in Wuhan. Yang Zhanqiu believes that asymptomatic infected people may have a green health code because they have no symptoms, which is not easy to be detected during security inspection at stations or docks and will become a risk factor.
Yang Jiong, chief expert of the Department of Respiratory and Critical Care Medicine of Zhongnan Hospital of Wuhan University, said recently that a large number of asymptomatic infected people in Wu Hanyou are still at risk of infection, although their infectivity is low. He believes that after the lifting of the ban, the population mobility has increased and needs to be handled with caution.
Yang Zhanqiu believes that asymptomatic infected people themselves carry less viruses, mainly through droplets. Passengers can effectively protect themselves after wearing masks, and do not need to worry too much.
In addition, after the unsealing, Wuhan is also facing the pressure brought by the increasing urban population on epidemic prevention and control. According to the announcement issued by Wuhan on the 7th, the public transport system in Wuhan is being started in an orderly manner, commercial activities and factory production are also gradually recovering, and the local epidemic prevention situation in Wuhan is also facing new challenges. According to the announcement, Wuhan will continue to strengthen community control, strictly manage entry and exit personnel, implement requirements such as identity, information recording, temperature measurement and wearing masks, and hold the front-line prevention and control positions in the community; In supermarkets, parks, hospitals and other open places, temperature detection, registration and flow control should be strictly implemented to prevent aggregate cross-infection.
Yang Zhanqiu said that although Wuhan began to unseal on the 8 th, the community isolation measures did not immediately relax. "The difference is that people who return to work need to enter and leave the community every day. But this is not a big problem. All units will have strict epidemic prevention measures, and they will also register for temperature measurement when entering and leaving the community. " According to Yang Zhanqiu's observation, on the first day of Wuhan's unsealing, the number of outdoor people in Wuhan did not increase much except for public spaces such as stations. "In theory, Wuhan is still Wuhan when the city was closed, but the population has decreased and the corresponding risks have become smaller."
The green code of gradually restoring social order in Wuhan is a passport for Wuhan residents to travel. Global Times reporters were asked to show their green codes when entering hotels and chain convenience stores. At present, the subway buses in Wuhan are gradually returning to normal frequency. From April 8, Wuhan will also resume taxi operation, and according to the epidemic situation and changes in market conditions, the network car operation will be resumed in due course. In the stage of resumption of work and production, the progress of catering enterprises is faster. As the epidemic prevention and control in COVID-19 is still in progress, catering enterprises are not allowed to accept customers' meals in the lobby. Therefore, the business volume of the take-away industry has soared recently, and there are even long queues at the entrance of some old restaurants. Customers can't eat in the store, so they can only place an order online with their mobile phones, and then take the meal home to enjoy.
Will the lifting of the ban in Wuhan cause a large number of people to "escape from Wuhan"? Mr. Zhao thinks it's too exaggerated. He said that the congestion relief in Wuhan only allows people stranded in Wuhan to go out, and people living in Wuhan don't want to go out. "Friends around me feel that Wuhan is safer than Guangzhou, Shanghai and other places, and the risks brought by importing these cities overseas are even higher than staying in Wuhan."
Yang Zhanqiu said that it was feasible to restore the social order in Wuhan before the outbreak of the epidemic, and now the conditions for restoring normal order have been met. In his view, the main need for prevention and control is the risk of new cases, focusing on monitoring the new incidence of floating population, especially the monitoring and management of fever patients, to see if there are COVID-19 patients.
