On December 26, the "Overall Plan for the Implementation of "Class B and B Control" for Novel Coronavirus Infection" was released, which aroused widespread concern from netizens.

From "Class B Tube A" to "Class B Tube B", what should ordinary people pay attention to in personal protection?

Who still needs nucleic acid testing and antigens?

What should the elderly pay attention to after infection?

CCTV News interviewed Li Tong, chief physician of the Department of Infectious Diseases at Beijing You'an Hospital, for further interpretation.

What are the categories of notifiable infectious diseases in my country?

According to what standard to divide?

  Li Tong once introduced that according to the outbreak and prevalence of infectious diseases, as well as their hazards, statutory infectious diseases in our country are divided into three categories: A, B, and C.

There are two types of Class A infectious diseases, plague and cholera; Class B infectious diseases are more familiar to everyone, such as AIDS, rabies, measles, epidemic hemorrhagic fever, epidemic cerebrospinal meningitis, and Japanese encephalitis; such as influenza , Mumps these are Class C infectious diseases.

After the "Class B and B Control", is the personal protection of ordinary people still necessary?

  Li Tong once believed that the new type of coronavirus infection has changed from the original "Class B A tube" to "B category B tube". From the perspective of prevention and control measures, there is no need for centralized isolation, no identification of close contacts, and no requirement Everyone has normalized nucleic acid testing, but we wear masks, wash hands frequently, open windows for ventilation, pay attention to social distance, pay attention to coughing etiquette and other measures are very helpful in preventing various respiratory infectious diseases.

So we should stick to it, because after all, the new coronavirus is still very contagious. For some elderly people with underlying diseases, they are still at risk of critical illness, so personal protection is still necessary.

What special attention should the elderly need to pay attention to once they are infected during this period?

  Li Tong once introduced that the Omicron mutant strain is occult. During the first week of infection, the symptoms of the elderly may not be severe. They may not have a high fever like that of young people. It may be just a low-grade fever. When the fever disappears, many people may I think it's okay.

In fact, pneumonia in the elderly may not start until four or five days into the course of the disease, and it is not serious until the sixth or seventh day.

Therefore, we must pay more attention to and take care of the elderly at home, observe their symptoms, and take the elderly to the hospital for treatment as soon as they experience symptoms such as suffocation and chest tightness.

After the "Class B and B tubes", which groups of people still need nucleic acid antigens?

  In the "Overall Plan for the Implementation of "Class B and B Control" for New Coronavirus Infection", it is required to adjust the crowd testing strategy, and community residents are "willing to do all the tests" according to needs, and no longer carry out nucleic acid screening for all staff. The "Plan" It also introduces the groups and scenarios that require antigen or nucleic acid detection.

  Li Tong once gave an example. For some specific groups of people, such as patients with fever and respiratory symptoms in medical institutions, nucleic acid antigens may be needed to confirm the cause when they want to identify the cause and treat symptoms.

Many people in nursing homes and social welfare institutions are vulnerable groups. Antigen or nucleic acid tests are regularly carried out for these groups and the staff of these places.

Nucleic acid antigen detection in some key institutions can also reduce the sudden impact of virus infection.
