At present, asymptomatic infected people do not need special treatment, but only centralized isolation medical observation. During the centralized isolation medical observation, asymptomatic infected people will undergo blood routine, CT imaging examination and antibody detection according to the situation. If there are related symptoms or signs in the follow-up and meet the diagnostic criteria of confirmed cases, they will be revised as confirmed cases and managed according to the treatment of confirmed cases.
Without treatment, is asymptomatic a case in COVID-19? Why should we concentrate on isolation?
Asymptomatic people are not patients, but asymptomatic people are still contagious and have infection risks to the surrounding people, and asymptomatic people may not always be asymptomatic. With the increase in the number of viruses in the body, cough, high fever and other related symptoms may occur at any time.
Today's asymptomatic cases may become mild or common cases tomorrow or the day after tomorrow. Centralized management is conducive to timely and targeted treatment. Centralized isolation of asymptomatic infected persons is a scientific and accurate prevention and control measure and is necessary.
Why is the proportion of asymptomatic infected people increasing?
1, the characteristics of the virus itself.
At present, the mutant strain of Omicron is very popular in the world. Although there are more and more mutations, the frequency is getting faster and faster, and the overall mutation is in the direction of weakening toxicity, but the infectivity is getting stronger and stronger, which is also the result of our human epidemic prevention. The direct harm of the virus to us has become smaller, but the prevention and control of it has also become stronger.
2. The results of mass vaccination.
Vaccination and epidemic prevention can greatly reduce the risk of virus infection. Vaccination enhances the body's immunity to a certain virus, and even if it is infected, some symptoms may not show up relatively.
3. It has a lot to do with our rapid screening and accurate flow adjustment.
Asymptomatic infection is a concept of point-in-time state. Some people are highly immune and may remain asymptomatic, and their bodies can eliminate the virus. Some people may change from asymptomatic cases to mild cases or ordinary cases. However, through regular screening of key populations and the flow of close contacts, we may find people before the virus propagates in the body.
Since the virus is very weak and basically asymptomatic, can I ignore it?
Of course not. The virus is only weaker than when it was first detected, and its immunity to healthy adults is weakened, but it is very dangerous to people with basic diseases. Most of the severe diseases now are people with basic diseases and elderly people with low resistance. China has a population of 65.438+0.4 billion, with such a large base, and belongs to an aging society. By the end of 2026.5438+0, China's elderly population aged 60 and above reached 267 million. In addition, China's medical resources are still very tight, especially in rural areas and remote mountainous areas. We can't afford the consequences of a sudden medical run.
Should we continue to prevent and control viruses like this?
No, we have been adjusting our prevention and control policies in time according to the variation of the virus. Now the isolation time has been greatly shortened, and the research and development of specific drugs and clinical trials have been stepped up. In addition, the popularization and promotion of vaccines continue. I believe that in the near future, we can go back to the time of 19, eat, drink and be merry, and leave.
