From 0:00 to 24:00 on October 20, there were 0 new local confirmed cases in the province, 240 new local asymptomatic infections (17 cases in Wuhan, 6 of which were detected at the isolation point and 2 of which were detected in the control area; Xiangyang City 13, 5 of which were detected at the isolation point and 8 of which were detected at the control area; Jingmen City 9, 4 of which were detected at the isolation point and 5 of which were detected at the control area; Enshi Prefecture 1), 0 new imported confirmed cases, and new imported asymptomatic infections 3 cases (2 cases were imported in South Korea, 1 case was imported in Indonesia ), 0 new suspected cases, 0 new deaths, 1 case was discharged on the same day (a confirmed case in Wuhan), 64 asymptomatic infections were released on the same day (20 cases in Wuhan, 216 cases in Xiantao City, 211 cases in Jingzhou City, 7 cases in Jingmen City, 23 cases in Huanggang City, 2 cases in Xiangyang City, 21 cases in Yichang City, 21 cases in Ezhou City; 3 cases were imported from abroad).
As of 24:00 on October 20, there were 6 local confirmed cases treated in , designated medical institutions in (5 cases in Xiangyang City, 1 ordinary case, 4 mild case; 21 cases in Huangshi City, 0 suspected cases. There are 462 local asymptomatic infections still under centralized isolation medical observation (177 cases in Wuhan, 60 cases in Xiangyang, 51 cases in Jingmen, 51 cases in Xiantao, 47 cases in Jingzhou, 22 cases in Huanggang, 22 cases in Suizhou, 22 cases in Enshi, 11 cases in Shiyan, 29 cases in Yichang, 7 cases in Xiaogan, 22 cases in Tianmen, 22 cases in , 1 case in Huangshi, 1 case in Ezhou, and 21 cases in Qianjiang).
1 imported confirmed case treated in designated medical institutions, which is mild; 27 imported asymptomatic infections are still under centralized quarantine medical observation.
The province has a total of 63,918 cases of cured and discharged from hospital, a total of 4,512 deaths, and a total of 68,437 confirmed cases of new coronary pneumonia have been reported. There are 226,497 close contacts with who are still under centralized isolation and medical observation.
At present, most of the people who have reported positive tests for the new coronavirus in China are asymptomatic infections. So, what are asymptomatic infections? Are asymptomatic infections contagious? What should the public pay attention to in their daily lives? Hubei disease control experts remind: You should know about asymptomatic infections!
What is Asymptomatic infection
Asymptomatic infection refers to those who have positive etiology tests for the new coronavirus but have no relevant clinical manifestations, such as fever, dry cough, fatigue, sore throat, decreased sense of smell (taste), diarrhea, etc., which can be self-perceived or clinically identified, and CT imaging does not have the imaging characteristics of the new coronavirus pneumonia.
How did the asymptomatic infected person
be discovered?
Asymptomatic infections are mainly discovered through close contacts and close contacts, inbound personnel, risk occupational population, personnel in key institutions and places, and people included in community management, etc., nucleic acid testing, , infection source tracking, epidemiological investigation, , and regional population active screening .
Asymptomatic infected persons
There is a risk of transmission
Asymptomatic infected persons are also contagious , mainly through the transmission of respiratory droplets and contact transmission to others.
propagates occultity. Since asymptomatic infected people do not have any obvious symptoms or signs, it is difficult to detect in the population. The transmission caused by asymptomatic infected people is difficult to prevent.
is not proactive in visiting medical treatment. Since the symptoms of asymptomatic infected persons are mild or atypical, the infected person may mistakenly believe that they are not infected with the new coronavirus and will not take the initiative to go to medical institutions for treatment.
is hard to detect. Due to the existence of a testing window, it is difficult to detect all asymptomatic infections by using nucleic acid testing and serological testing methods. The existing asymptomatic infections are mainly discovered through active screening of close contacts of the case, investigation of infection sources, investigation of clustered epidemics and active testing of high-risk personnel.
Reasons for the increase in asymptomatic infections
With the continuous mutation of the new coronavirus, the currently popular Omickron mutant strain has increased infectivity, its toxicity is relatively weak, and its clinical symptoms are relatively mild, which will cause many infected people to show no clinical symptoms after infection.
is related to large-scale population immunization. The coverage rate of vaccination is now high. After vaccination, the human body's immunity is enhanced. Even if it is infected, some symptoms may not be shown, and vaccination is still very effective.
is related to early detection. Due to the rapid screening and rapid discovery of the disease control team, some early infections were quickly discovered and detected before they had time to develop symptoms. The more meticulous the work on , the higher the probability of "intercepting" infected people in the early stage, and the more timely disease transmission control is. Asymptomatic infected people are the people who are "intercepted" in the early stage.
Asymptomatic infected people need treatment
At present, asymptomatic infected people do not need special treatment, they only need to undergo centralized isolation and medical observation . During centralized medical observation, asymptomatic infected people will conduct routine blood, CT imaging examinations and antibody testing according to the situation. If relevant symptoms or signs appear in the future and meet the diagnostic criteria for confirmed cases, they will be revised to a confirmed case and will be treated as a confirmed case.
has no obvious symptoms for asymptomatic infections, but is contagious and concealed. Hubei disease control experts remind: In daily life, the public should not relax their vigilance. should continue to strengthen self-protection and develop healthy lifestyles such as washing hands frequently, wearing masks, ventilating frequently, not gathering, one-meter line, separate meals, sneezing and covering their mouths and noses. Especially when entering and leaving public places, taking transportation, and entering crowded places, they should wear masks scientifically; should actively get vaccinated to build an immune barrier; Actively cooperate with the community to complete the nucleic acid screening , if an individual has positive nucleic acid test, there is no need to panic, and cooperate with medical and health institutions to do a good job in health monitoring and isolation medical observation.
