Why should asymptomatic infected persons be quarantined for medical observation?Do nucleic acid when the health cloud can not open how to do?Wu Jinglei said so…

Youth Daily Shanghai reporter CAI Xian/Wen Changxin/Wu Jinglei, director of the Municipal Health Commission, said that the nucleic acid test of the asymptomatic infected person was positive, but there was no clinical manifestation and no imaging manifestation.Asymptomatic infected persons must be reported in accordance with the national prevention and control plan and corresponding measures taken.As you mentioned, there are many asymptomatic cases this time.Internationally, asymptomatic novel coronavirus infections in the early stage are gradually increasing, especially after omicron became the main epidemic strain recently, the number of asymptomatic COVID-19 cases can reach 80-90%. At present, the proportion of asymptomatic COVID-19 cases in Shanghai is similar to the data of other countries and regions.The main reasons are: one is the reduction of the virulence of the omicron virus strain itself.Studies have shown that omicron strain infection mainly affects the upper respiratory tract, less lower respiratory tract, significantly reducing the proportion of symptoms.Second, large-scale vaccination of the population has played a very important role in protecting the vast susceptible population.According to our analysis of the cases, the proportion of vaccination in all cases reached about 94%, the incidence of severe illness was reduced to 0.1%, and none developed to critical illness.These data suggest that vaccines have a very important impact in reducing symptoms.Third, more asymptomatic infected persons will be screened by proactive screening after the detection rate is increased. With the advance of a large number of epidemiological investigations, the screening capacity and scope will be larger. After the outbreak of the epidemic, the close contacts, sub-close contacts and risk groups will soon be controlled.These measures lead to the rapid detection of infected persons during the incubation period and to a higher proportion of asymptomatic cases in early active screening.As for the centralized isolation and treatment of asymptomatic infected persons, the key to the control of infectious diseases is to control the source of infection, cut off the route of transmission and protect the susceptible population.Asymptomatic infected persons do not mean that the infectivity is low, so it is necessary to implement centralized isolation measures for asymptomatic infected persons to control the source of infection and block transmission.Second, management needs, asymptomatic infection medical observation of asymptomatic infections occur the change of the condition, especially in the elderly, has been injected with the vaccine, obesity, severe basic diseases, may arise from asymptomatic to have symptoms, even for the development of intensive, found in medical observation period to facilitate staff timely treatment.As for the treatment, similar to those with mild symptoms, clinical observation and follow-up were carried out for these patients, and risk assessment was carried out. Meanwhile, the primary disease was treated, supplemented with TRADITIONAL Chinese medicine treatment according to the actual situation, and body functions were adjusted.Today, many citizens complain that the health cloud cannot be opened during nucleic acid processing, which leads to the slow progress of nucleic acid sampling in the community. What measures can be taken to deal with this?Wu jinglei said the amount of nucleic acid samples has continued to rise since the outbreak.Since March 11, the daily nucleic acid registration and sampling volume have both exceeded 5 million.On the basis of the previous high operation, the number of nucleic acid test registrations in the system reached 4.33 million this morning, double that of the same period yesterday.From the point of view of now, the whole health cloud system is normal. As for us, carrying out the screening this time brought inconvenience to the citizens, we are especially sorry. Although we expected these situations at that time, there was still some difficulty, so we had to take measures to limit the flow.Since the new round of screening in key areas today, some people have reported that the health cloud system cannot be opened temporarily or there is a delay. We have noticed these problems this morning.Due to the large number of samplers, the nucleic acid detection system of The Health Cloud had problems such as high burst volume and login difficulty.In order to ensure the stable operation of the system, we have implemented traffic limiting measures and gradually adjusted the traffic volume when it reaches a certain value.After verification, the system is not smooth system failure, but the current limiting protection measures.Since the Spring Festival, the system has been upgraded and expanded several times.In response to the problems encountered in the operation of large-scale nucleic acid testing, we promptly optimized the system. First, we continued to upgrade and expand capacity, strengthened monitoring of the operation, and immediately intervened in the event of problems to ensure the safe operation of the system.Second, strengthen the linkage and coordination with the bid and health cloud, and the municipal big data center takes the initiative to do a good job in the connection of relevant technologies.Third, all districts are requested to strengthen the screening organization, so as to achieve staggered peak, orderly organization, sampling in batches, to avoid large crowds queuing for health cloud registration at the same time.We also remind the public that in case of a large number of visitors to the system, the registration code can be saved as a screensaver, which can further improve the efficiency of on-site verification.If the nucleic acid results report is queried, it can also be queried through suibid APP, SuiBid Alipay and wechat mini program.Inconvenience, hope to get the understanding of the general public friends.Youth Daily Shanghai reporter CAI Xian/Wen Changxin/photo editor: Lu Tianyi
