What should I pay attention to in the prevention and control of the epidemic?Listen to what Huaxi experts say

What are the new changes in the Chengdu epidemic? What should citizens pay attention to the prevention and control of the epidemic? For a series of epidemic prevention issues that citizens are concerned about, the reporter today invited Zong Zhiyong, deputy team leader of the Sichuan University Huaxi Hospital Infectious Disease Center, the deputy leader of the Sichuan Provincial New Guan Guan Pneumonia Medical Real Estate Group and the hospital infection prevention and control team leader. Essence

1. What are the new changes in Chengdu's epidemic in this round?

There are several main characteristics in the Chengdu epidemic in this round. One is that they come suddenly and progress quickly; the other is that case transmission is aggregated, mainly in the same unit, the same family, or the same time and space. The third is that the proportion of symptoms such as fever (low heat) is higher, but the symptoms are still mild in general. The chest CT of only individual patients indicates that there is pneumonia.

2. What are the new characteristics of the latest discovered mutant strains in terms of communication and transmission speed?

By sequencing for the initial patients, this time was BA.2.12.1, Omikon's mutant strain. This mutant plant was first discovered in the United States. On May 4 this year, the World Health Organization reminded BA.2.12.1 closely. According to the "China Disease Control Center Weekly (English)" report, my country also discovered the first case of diagnosis of the mutant strain in May this year, which was entered overseas.

Studies have shown that BA.2.12.1 is more infectious and immune to escape compared with other Omircong mutant strains. BA.2.12.1 evolved from BA.2, and some studies have shown that its communication rate is about 25%higher than BA.2. The stronger immunity escapes means that after the vaccine or infected with other new coronal virus strains before, there is still a certain possibility that it will be infected by BA.2.12.1 again. Of course, the risk of infection after vaccination is far less than those who have not vaccinated.

Although the virus strain has become easier to spread, the virus toxicity has not been enhanced, so you don't have to worry too much.

3. What are the difficulties of the emergence of new mutant plants to the epidemic prevention and control? How long is its incubation period?

Due to the faster and more hidden transmission of new mutant strains, this puts forward the requirements of "higher, faster, and stronger" for the prevention and control of the epidemic. There are many difficulties in preventing and controlling. First, it is fast, grab time, and after discovering positive infection, they must race with the virus, that is, to strive for the virus spread, intercept it, and minimize the scope of their transmission. The second is that there must be "fish that leaks". On the entire spread chain of the new crown, all those who may be infected should be found to avoid quickly forming a new source of infection and causing new communication. The third is to be accurate, "hit the key", after all, infected with effective anti -epidemic measures in my country, after all, there are very few infections. After all, there are very few infections.

The incubation period depends on various factors such as the situation and the status of autoimmune. From the perspective of existing information, the latent period of the mutant strain is short and usually does not exceed 5 days.

4. What should you pay attention to in the epidemic prevention and control?

In fact, the most effective measure is the most basic measure we have repeatedly emphasized. Four -piece epidemic prevention: wear a mask (unless you are alone, or maintain a social distance with people with good ventilation), and work hard (to do it with people), work hard ( Including mucous membranes in the eye, mouth, nose, etc.), avoiding crowds (not dinner, no gathering), vaccination.

Also pay attention to:

1. Symptoms have long -treated medical treatment. Because the symptoms of the new coronary virus infection are not specific, similar to ordinary colds and flu. Especially in the summer, many people have cold -like symptoms after blowing the air conditioner for a long time. They think that they have "air -conditioning disease" and do not go to the doctor by themselves. This has created obstacles for early discovery. In order to discover early, everyone should seek medical treatment in time when symptoms such as fever, cough, sore throat, and headache to avoid luck.

2. Check your own trajectory in time. Because of the fast transmission speed, this requires everyone to check the trajectory issued by the illness and control department in a timely manner. At the same time, pay attention to the receiving text messages received. The trajectory cross or risk zone history must be reported in a timely manner.

5. There are many vaccines in confirmed cases. Is the vaccine useful?Do you still inoculate the needle?The vaccine is of course useful. It does not mean that it is 100%, nor does it need to reach 100%.There are multiple levels of vaccine use, including significantly reduced risk of infection when infection, significantly reduced the risk of severe illness and death after infection, and can also indirectly protect family members, friends and relatives.Even for Omikon mutant strains, some data show that inocus in the densely connected population can reduce the risk of infection by three times, which shows that the immunity is effective.

Therefore, it is recommended that if there is no contraindication, it should be taken over, especially the elderly who meet the conditions of vaccination. It is recommended to vaccinate as soon as possible.It is also recommended to strengthen as soon as possible for people who meet the conditions for inoculation.
