Why are there so much proportion of those with no symptoms in this round of epidemic? What treatment measures are taken for different types of infected people? On September 11th, at the press conference of the Guiyang Gui'an New Guan Pneumonia's epidemic, Shi Xiaoyu, deputy director of the Guiyang City Health and Health Bureau, answered the concern of the general public.

Positive infection refers to the detection of nucleic acid, and the result is positive personnel. Patients are likely to be infected with new coronary viruses, but they cannot be diagnosed. They need to be repeatedly adopted by the disease control department to eliminate false positives. After the initial sieve positive reciprocity, it is still positive. The clinicians will be diagnosed according to the results of clinical symptoms, laboratory examinations and imaging examinations. If there are no clinical symptoms, and there are no obvious abnormalities for blood routine and chest CT results, that is, being diagnosed with new coronary virus infections, that is, asymptomatic infection.

If clinical symptoms such as fever, fatigue, smell (smell) loss or lack of clinical symptoms, or abnormalities such as blood conventional white blood cells, lymphocytes, or chest CT examinations have exudate lesions, they are diagnosed as confirmed cases and diagnosed diagnosis. The case can be divided into four types: light, ordinary, heavy, and critical type.

Why are there so many asymptomatic infected people this time?

According to the analysis of provincial medical and control experts, on the one hand, the transmission of poisons in Guiyang's this round of epidemic transmission was clearly sequensed as a new crown virus Omikon BA.2.76 mutant strains. The strain has a strong transmission and hiddenness, but the toxic force is relatively low, the pathogenic force decreases, and the symptoms caused by are relatively mild. Therefore, asymptomatic infection accounts for relatively high.

On the other hand, the new crown virus vaccine has a great protective effect on preventing severe illnesses and preventing death. With the inoculation of new crown vaccines in large -scale people, the proportion of severe and hazardous types after infection is significantly reduced. Through early fast nucleic acid screening, some early infected people were discovered before they showed clinical symptoms. Therefore, the proportion of those with asymptomatic infections in this round of epidemic situation is relatively high.

So what treatment measures should be taken to different types of infected people?

Shi Xiaoyu said that those infected with new crown virus infected by classification and stratification were categorized to ensure that patients were treated in a timely and effective treatment. At present, Guizhou Province's overall planning for medical resources in the province to infected all new coronal viruses in the province will "accept it". Those with light and asymptomatic infections are treated with square cabin hospitals; infections with general types, severe, and high -risk factors, they are treated to designated hospitals.

Symptoms of non -symptoms generally do not need special treatment, but it is contagious, so it is necessary to observe medical observation. Some cases may occur in related clinical manifestations in the future, and may be converted to confirmed cases. The confirmed cases need to be isolated and treated in designated hospitals, mainly for general treatment and drug treatment. As of now, the patients received by the hospital were stable.
