The evening of March 29 to March 30, Henan native new cases implicated three asymptomatic infected people. People’s Daily health client reporter incomplete statistics, over the past few days, Hubei Jingmen City, Shandong Qingdao, Henan Luohe and other places appeared asymptomatic infected. Why are asymptomatic infected people not counted as confirmed cases? Although the nucleic acid test or IgM antibody test is positive, but asymptomatic infected people are not included in the confirmed cases. Hubei Province, one of the members of the epidemic prevention expert group, Huake Tongji Hospital, chief physician of the Department of Infectious Diseases, Song Jianxin told reporters that the current new crown pneumonia cases are diagnosed according to the symptoms, there are clinical symptoms coupled with the genetic testing of the new crown virus is considered a confirmed case. But if the genes contain the virus to diagnose patients, the nucleic acid test positive asymptomatic patients should also be considered a confirmed case. However, clinically speaking, a patient is only a patient if he is “sick” (that is, symptomatic). How can a person be said to be sick if he is not coughing and does not have any physical discomfort? According to the definition of the “Diagnostic and Treatment Program for Novel Coronavirus Pneumonia (Trial Version 7)”, suspected and confirmed cases need to have clinical manifestations. Asymptomatic infected persons need to be intensively isolated for 14 days and undergo further tests to make a judgment because they have no clinical manifestations. Wang Hufeng, Director of the Healthcare Reform Research Center of Renmin University of China and Professor at the School of Public Administration of Renmin University of China, mentioned that asymptomatic infected patients, like symptomatic patients, also exist in the incubation period, onset period, and healing period. However, due to the lack of symptoms, a positive nucleic acid test can only indicate that they have been infected before, and it is not easy to determine to which stage this type of patient belongs, and it is difficult to diagnose them as a case. Not only the new crown pneumonia, other diseases diagnosis, also need laboratory test indicators combined with clinical symptoms to determine. “If a patient has been screened, even if it is not included in the confirmed cases, it has to be isolated and not considered as a safe and uninfected population. It can not be ignored with relaxation of vigilance.” Song Jianxin believes. On March 30, Li Keqiang, a member of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee, Premier of the State Council, and head of the Central Leading Group for Responding to the New Crown Pneumonia Epidemic, chaired a meeting of the leading group. The meeting called for the discovery of asymptomatic infected persons, immediately according to the “four early” requirements, strict centralized isolation and medical management, open and transparent release of information. Will asymptomatic infected people infect others? “Asymptomatic infected people, also known as invisible infected people, do not have any symptoms themselves, but the nucleic acid test or IgM antibody test is positive.” Song told reporters, but it is just as infectious as symptomatic patients, with roughly the same routes and rates of transmission. According to the Henan Provincial Health Commission news on March 29, March 28, Henan Province, a new new local confirmed cases of new crown pneumonia, the patient is Luohe City Wang Moumou. March 21, Wang Moumou had gone to his hometown of Pingdingshan City, 郏县, accompanied by classmates Zhang Moumou (郏县人民医院医生) driving to the countryside to sweep the tomb, and dined together three times, while Zhang Moumou Department of the asymptomatic infected person. In the morning of March 27, Zhejiang Province reported a new case of “overseas imported cases associated with local confirmed cases”, which raised concerns. Zhejiang Provincial Health Commission and Jiaxing City, Jinhua City, Wenzhou Municipal Health Commission has issued briefings on the situation, the confirmed case has returned to an asymptomatic infected people outside the country have had up to 8 hours of the same plane experience. Wang Hufeng believes that, for asymptomatic infected, found a case of rapid response to isolation, control the scope of transmission can play a preventive effect. Wang Hufeng suggested, engaged in personnel contact with more work, such as train operators, flight attendants, and personnel from the high incidence of the epidemic in the region should be examined accordingly, for the conditions of the region as well as enterprises, these personnel can be screened for nucleic acid testing. Can an asymptomatic infected person cause a second wave of transmission peaks? “The chances of this are very small, and the public does not need to panic.” Song Jianxin believes that from the category of infectious diseases, the proportion of asymptomatic infected people is very small, and this type of patient’s own immunity is strong, carrying the virus will not be too long. However, it is important to note that this type of patients will be infected with the virus to others, the infected person is a mild or severe disease is determined by the infected person’s own body immunity, so the contagiousness of asymptomatic infected people can not be ignored. “Such asymptomatic infected people are also known as disseminated cases in infectious diseases, and the possibility of such disseminated cases causing a large-scale outbreak of infectious diseases is very low.” Song Jianxin believes that with the current prevention and control detection system, a large-scale spread of the virus will not be formed if a disseminated case is isolated as soon as it appears. With the local new new crown patients “clearing out” around the world, localities are beginning to resume work and school. Wang Hufeng believes that the emergence of asymptomatic infected people is feared to have a certain impact on the resumption of work and school. This is essentially a trade-off, the current stage, all can be resolved online work and teaching, as far as possible, mainly online, but the necessary production and learning activities will continue, but to be vigilant, to avoid the rebound of the epidemic. For those who must return to work and school, there is no need to worry and panic too much about asymptomatic infected people. Source: Health Times
