Since this round of epidemic, why is the proportion of asymptomatic infected among the positive infections that have been reported? What is the first sieve positive? What is a positive infection? How to review and diagnose the initial sieve positive? What treatment measures are taken for different types of infected people? Zhou Jianrong, a member of the provincial treatment expert group and deputy dean of the General Shan Hospital, answered.

What is the first sieve positive?

Zhou Hourong: The first sieve positive is the first nucleic acid detection or screening result is positive personnel. He is likely to be infected with the new coronal virus, but he cannot confirm the diagnosis.

What processes will be taken to review and diagnose the first sieve positive?

Zhou Hourong: Positive personnel, after re -examination, after re -examination, nucleic acid is still positive, that is, a new coronal virus infection (or positive infection). At this time, clinicians will be diagnosed according to clinical symptoms, blood routine and chest CT examination results. If there are no clinical symptoms, and the blood routine and the CT results of the chest have no obvious abnormalities, they are diagnosed as a new type of coronary virus infection (asymptomatic infection). If clinical symptoms such as fever, fatigue, smell (smell) loss or lack of clinical symptoms, or decreased blood conventional white blood cells or lymphocytes, or abnormalities such as exudation lesions on the chest New coronary virus pneumonia.

After this epidemic, in order to allow citizens to understand the development trend of the epidemic in a timely manner, Guiyang City announced the data of first -sieve positive and positive infections for the first time. After the results come out, the notification will be issued in time.

What is a positive infection?

Zhou Hourong: Positive infection refers to patients who have a positive sieve positive for the new coronary virus nucleic acid test and are still positive by the superior institution, including asymptomatic infections and confirmed cases.

What are asymptomatic infections? What are the differences between asymptomatic infections and confirmed cases?

Zhou Hourong: Asymptomatic infections and confirmed cases are positive personnel of new coronal virus nucleic acid testing, the main difference is that clinical manifestations and chest CT results.

Symptoms of non -symptoms are usually no symptoms such as fever, cough, sore throat, fatigue, taste (smell) loss or lack of symptoms, and people who have not found abnormal lesions such as exudation lesions through the chest CT examination. However, the results of the new coronary virus nucleic acid test are positive, and they are called asymptomatic infections.

The confirmed case refers to the results of the new coronary virus nucleic acid test, and at the same time accompanied by clinical symptoms such as fever, cough or dry cough, sore throat, smell (smell) loss, or lack of lack, blood conventional leukocytes or lymphocytes decrease, or chest CT examinations are available Abnormal conditions such as exudation lesions are diagnosed as new coronary virus pneumonia. According to the severity, it can be divided into four types: light, ordinary, heavy, and harsh.

Why does the proportion of asymptomatic infected people this time?

Zhou Hourong: On the one hand, the transmission of poisons in Guiyang's this round of epidemic transmission is clearly sequensed as the 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.

What treatment measures are taken for different types of infected people?

Zhou Hourong: The National "New Coronatte Pneumonic Pneumonia Diagnosis and Treatment Plan (Trial Ninth Edition)" clearly states that those who are infected with new coronary virus must be categorized, and those with mild and asymptomatic infections should be treated to the square cabin hospital; The infected person is treated to a designated hospital. At present, the province's overall planning for medical resources in the province to infected all new coronal viruses in our province can "accept it". Symptoms of non -symptoms generally do not need special treatment, but they are contagious, so they need to observe medical observation. In some cases, related clinical manifestations may occur and can be converted to confirmed cases. The confirmed cases need to be isolated and treated in designated hospitals, mainly for general treatment and drug treatment. While bed rest, nutritional support, and monitoring of life signs, according to clinical types and high -risk factors, comprehensive treatment of Paxlovid, Lianhua Qingjuan capsules, and traditional Chinese medicine soup agents. In short, we will carefully formulate a diagnosis and treatment plan, carry out standardized diagnosis and treatment of each patient, strive to achieve the best results, and do our best to promote the patient's early recovery of patients.
