Academician Zhang Boli said in an urgent voice: People who have been positive should also pay attention to protection, and do the following to prevent the recovery of yang!

Many people believe that after being infected with COVID-19, the human body will produce corresponding antibodies, and then go out to be immune. However, according to the media report on December 16, Zhang Boli, an academician of the Chinese Academy of Engineering, said urgently that currently the variant strain of Umicorn has multiple subtypes, and it is difficult for the human body to establish a comprehensive immune barrier in the face of multiple subtypes. Although the probability of being infected again within three to six months after infection with COVID-19 is relatively small, due to the constant variation of the virus, Another variant may infect people who have been positive again.

Academician Zhang Boli reminded that the variation of the virus will cause infection of different subtypes, and the specificity of the neutralizing antibody produced will be reduced, and the ability of the antibody to intercept the new variant subtype will be reduced. Therefore, after being infected with COVID-19, a small number of people are still likely to be infected by the variant virus again. Therefore, for COVID-19 infected people, during the epidemic, The best way is to do a good job of protection and effectively reduce the risk of recovery. Academician Zhang Boli also suggested that people who have not been infected should continue to do a good job of protection, while those who have been positive should not be careless, and the following five points should also be done to do a good job of personal protection.

1、 Wear a mask 。

Three years after the epidemic, we found that wearing masks is the most simple and effective way. We must insist on wearing masks and instruct our families to wear masks. We must insist that one person has a cold, and the whole family should wear masks. The masks we have worn should be replaced every day. If you touch the masks, you should not touch your mouth and nose to prevent infection. Among the masks, try to choose the N95 medical mask. It has a large breathing space and won't feel stuffy when worn. The multi-layer thickened protection can better isolate the spread of viruses. There are many types of N95 masks that can also be used to beautify the face.

2、 Wash hands frequently 。

It is also very important to maintain personal hygiene, especially hand hygiene. Usually, you should wash your hands before meals and after defecation. Once you have touched something unsanitary, you should wash your hands. You can use sterilized soap to clean your hands. You can also use clean water to wash your hands, and then use wash free gel to disinfect your hands. Only after your hands are washed, can you not send the virus into your mouth, So as to prevent infection.

3、 Kill frequently 。

Once an infection is found, the family should kill it regularly. You can use 84 disinfectant to wipe the used things. Doors and windows, handrails, and bowls and chopsticks used by infected people should be sterilized at high temperature. 75% alcohol disinfectant should be sprayed at home. Clothes and bedding should also be diluted and soaked with disinfectant before cleaning. At the same time, the family should keep the windows open frequently, at least half an hour a day, so that the air can circulate, The air at home will be much fresher

4、 Do not gather 。

During this period of time, we try our best to avoid going out. We don't want to gather together or go to places where there are many people. Especially, we don't want to go to dinner parties, because dinner parties are one of the ways most likely to be infected with viruses. When people have dinner together, they can eat together with you and me in the same dish. Think about it. If someone has been infected by this time, you can have dinner with them, Does it send the virus directly into the body? Therefore, reducing unnecessary dinners is also one of the best protection measures.

5、 Keep social distance 。

Many people say that what should we do if we have to go out to work? If we have to go out, we can only take the above protective measures before going out. After going out, we should keep a certain social distance. Now, we basically advocate the one meter line, which means that people should keep a distance of one meter from each other. Do not be close together, causing infection. If you feel dangerous, use disinfectant to spray and sterilize your hands in time to reduce the chance of infection.

In addition, Zhang Boli also suggested that the elderly with basic diseases should be vaccinated if there is no absolute contraindication. Although the vaccine cannot avoid infection, the data at home and abroad suggest that it is effective in preventing severe diseases.
