Recently, there have been outbreaks of epidemics in various parts of the country, which also makes everyone feel the power of virus mutation strains once again. On April 2, there were 438 new confirmed cases in Shanghai and 7,788 new asymptomatic infections. The cumulative number of infections in the past three days has exceeded 19,000, of which asymptomatic infections have exceeded 17,000, accounting for more than 94%. Chen Erzhen, head of the medical treatment team at Shanghai centralized isolation point and vice president of Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine, said in an interview with People’s Daily Dajiangdong Studio: “From the development of the entire epidemic situation, if the number of asymptomatic infections is If there are too many, you can isolate yourself at home if you have the conditions.” “Of course, we have to cooperate with some measures of home control, the most important thing is the issue of personal compliance, to ensure that asymptomatic infected people strictly control themselves and do personal protection in accordance with the norms. Otherwise, there will be no way to achieve the effect of blocking the spread.” Chen Erzhen added.
Professor Chen Li from Fudan University School of Medicine agreed with this view. He told the “Physician Daily” reporter that Chen Erzhen suggested that the solution is not only to solve the current problems in Shanghai, but also to solve the new crown in the future. From an epidemiological point of view, the positive inflection point of the new crown epidemic prevention and control, including the reduction of the fatality rate, severe disease rate and hospitalization rate of the new crown virus infection, the guarantee of the consultation rate and the isolation rate (hereinafter referred to as the “five rates of new infections”), and The decline in the number of new coronavirus infections, etc.
How to recognize and define the psychological timing of the victory of the new crown prevention and control is a major challenge faced by the world, the whole society and the whole people. Chen Li believes that the psychological time point for the public to accept the “post-new crown era” should be that the hospitalization rate drops below a specific baseline under the premise that the new infection rate is guaranteed. Because even if the fatality rate and severe illness rate of the new coronavirus infection drop significantly, the hospitalization rate of the new coronavirus infection does not drop, it will still bring difficulties to the medical system. “Of course, the sharp drop in the number of people infected with the new coronavirus is the ultimate independent indicator of the victory in the fight against the epidemic.” Chen Li added, “For the final victory in the fight against the epidemic, we need to pay serious attention to the dynamic changes in the ‘five rate of new infections’. From a professional perspective, make timely analysis and judgment, and do a good job in explaining and promoting.”
April 2nd 0 – At 24:00, 31 provinces (autonomous regions and municipalities directly under the Central Government) and the Xinjiang Production and Construction Corps reported 1,506 new confirmed cases and 11,781 asymptomatic infections [1]. Although the current “New Coronavirus Pneumonia Prevention and Control Plan (Eighth Edition)”, in the “epidemic monitoring” section, the “discovery report of asymptomatic infections” is mentioned, and it is required that the discovered asymptomatic infections should be detected within 2 hours. Online direct reporting through the China Disease Prevention and Control Information System, and should be promptly transferred to designated medical institutions for centralized isolation and medical observation. If relevant symptoms or signs appear in the future, it should be corrected as a confirmed case within 24 hours.
But it should be noted that the new coronavirus has mutated to the Omicron virus and is highly contagious, and the infected people are mainly asymptomatic virus carriers. “Even if the infected people show symptoms, they are mostly confined to the upper respiratory tract, the incidence of lower respiratory tract infection and pneumonia is low, and the severe rate and mortality rate are lower. In addition, more than 3 billion people have been vaccinated against the new crown in China, and prevention and control measures are moving towards Therefore, we should consider the possibility of home isolation of asymptomatic infected persons in order to achieve the purpose of reducing the cost of epidemic prevention.” An expert in Shanghai who did not want to be named also agreed with Chen Erzhen. He also told reporters, “If this idea can really be realized, it is necessary to further formulate relatively clear implementation rules and monitoring measures to ensure the final isolation effect. “
Chen Erzhen also mentioned: “Although no patients with severe respiratory failure have been found, the characteristics of the patient population should also be considered. After the COVID-19 hit, the coping ability has declined, and they may become high-risk patients. Therefore, there are also relevant plans for high-risk patients at present, and resources are arranged according to the principle of ‘preferring to prepare rather than use, not to prepare when unavailable’.”
< p>Chen Li takes this seriously, and believes that when “preparation and not use” becomes a reality, it will be the time when the “five rates of new senses” reach the standard.
