What happens to an asymptomatic infected person?

Asymptomatic infections.

What are the symptoms.

COVID. The prodromal or latent period of the disease is usually 3 to 7 days, during which there are no symptoms, but after 3 to 7 days, fever will appear.

Symptoms such as cough and fatigue. Doing nucleic acid testing.

After that, they are positive, and they are actually infected people with very mild symptoms, and this condition also accounts for a significant number of people. If the second nucleic acid test becomes negative, and the antibodies are also negative, then it is not a new crown pneumonia patient at all. However, if it is still positive for the second time, then it is an asymptomatic infection.

In addition, there are very few people who are tested positive for nucleic acid, and have done many nucleic acid tests that are all positive, and do not produce antibodies, we call these people "virus carriers".

Knowledge development: which groups of people are asymptomatic infections.

1. Close contacts of new crown pneumonia cases.

It was found during nucleic acid testing during the medical observation period.

2. Exposed populations, asymptomatic infections may be found during active testing of exposed populations.

3. Asymptomatic infections may be found when people with new crown pneumonia cases, travel history and residence history in areas of continuous transmission are actively tested.

Asymptomatic infection, as the name suggests, is an infected patient who does not show any clinical signs and symptoms, which is mainly due to the patient's strong autoimmunity, bacteria or viruses cause infection, and the human body does not show corresponding obvious symptoms.

However, through imaging tests, asymptomatic infections of the new coronavirus have been detected this year. There are no obvious clinical signs and symptoms in this population, but chest CT or x-ray may be altered, and nucleic acid is also positive on sputum specimens.

Asymptomatic infection is a concept that has always existed in infectious diseases - there are no symptoms, but they have positive indicators of etiology, and some people will also have our antibody response. If a person is infected with the virus, has no symptoms after a period of time, and finally turns negative with nucleic acid, it is an asymptomatic infection. In this case, we think that the natural process of his illness has been completed, and he has been asymptomatic during the completion of the process, which is called asymptomatic infection.

It must have been obtained from a certain place, and there must have been a history of contact, but it is just that the history of contact can you find it very clearly. But how contagious asymptomatic infected people are, there are not many reports now. If a person is infected with the virus and does not get sick, first of all, he is in good health, secondly, the virulence of the virus is relatively weak, and thirdly, the number of viruses he has been exposed to is relatively small, so he may not get sick.

The contagiousness of asymptomatic infected people will definitely be low, but how low it is, or whether it is already low enough to be gone, really needs to be observed. We now say that as long as there is a positive test, we attach great importance to it and have to do some isolation measures. He will stay in the isolation point for 14 days, and if he is in the isolation point, he will be tested twice to ensure that he is indeed negative, and then he will be released from isolation.

So basically, they don't have a chance to infect other people, that is, whether he is contagious or not, we still treat this kind of confirmed patient. Asymptomatic infected people may need to have a full physical examination if they are to be truly screened. The physical examination needs to check nucleic acid, a blood routine is required, and we also recommend that a lung CT be done if possible.

Asymptomatic infections refer to patients who have not developed symptoms related to the new coronavirus after being infected with the new coronavirus through droplet transmission and contact transmission due to the type and number of invading viruses and the patient's own immune system response, but it should be noted that asymptomatic infections are contagious.

Generally, it is due to the patient's own righteousness is relatively sufficient (usually the body's immunity is relatively strong, and it is not easy to get sick), the human body itself has righteousness, external evil attacks, righteousness and evil qi are opposed, the winner generally does not show symptoms, and the loser generally shows symptoms.

Asymptomatic infected people refer to people who are infected by the new coronavirus but have no clinical symptoms (such as fever, cough, sore throat, etc.), but the respiratory tract and other specimens are positive for the etiology of the novel coronavirus or serum specific IgM antibodies.

Asymptomatic infected persons should still be subject to strict management measures, and asymptomatic infected persons should be isolated for 14 days, and after the expiration of the isolation period, in principle, those who have tested negative for two consecutive specimens can be released from isolation. If symptoms develop during the isolation period, they should be admitted to the hospital immediately.

Infected people without symptoms of cherry hunger were mainly found through close contact screening, cluster outbreak investigation and source tracing investigation. A small number of asymptomatic infections may develop into confirmed cases, but the vast majority will recover on their own.

Asymptomatic infections can also be a source of infection and have a certain risk of transmission. At present, the treatment of asymptomatic infected people is to isolate them when they are found, continue to conduct nucleic acid testing during the isolation period and further observe whether they have symptoms, and they can also be intervened with some antiviral drugs. In principle, the isolation can only be released after two consecutive negative nucleic acid tests of specimens.

Among <> new crown pneumonia patients, asymptomatic people are in the minority. Most people in the cave are infected with the new coronavirus, causing the new coronavirus pneumonia, after the incubation period of onset, there will be more obvious symptoms such as physical fatigue and fatigue, as the disease progresses, there will be fever, dry cough, and breathing difficulties. Symptomatic patients are easy to find and diagnose, and can be hospitalized and isolated in a timely manner after diagnosis** to reduce the chance of infection.

However, a small number of asymptomatic infected people, after being infected with the virus, will not cause abnormal symptoms in the body due to factors such as the low amount of virus in the body. Therefore, if these infected people are not diagnosed in time and take isolation measures, they can easily become a very dangerous source of infection and infect more healthy people.

The occurrence of asymptomatic infections is mainly related to the autoimmune function and the number of infected viruses. In addition, it is possible that the incubation period is long, so there are no symptoms. When asymptomatic infection occurs, isolation should be carried out, if after the incubation period of 14 days, no symptoms appear, should be retested, if the test result is still positive, it should be noted that continued positive results may also have a certain degree of contagiousness.

Pay attention to strengthening physical exercise, eat more fresh vegetables and fruits, and enhance the body's ability to resist diseases.
