When did COVID-19 find out?

COVID-19 is as fierce as a tiger. Since its appearance, it has brought a lot of trouble to people. Its infectivity is frightening, especially when it just broke out, and the protective measures were not in place, which led to many people being infected. Now COVID-19 has changed again and become more contagious. We should pay more attention to epidemic prevention. However, the epidemic reported online, a family of four and three in Beijing has been diagnosed, and the other one is not infected. Some people think it is suspicious.

First,? Three people in a family of four were diagnosed with COVID-19, and one was asymptomatic. Since the outbreak of COVID-19 last year, people are now scared to death. Until now, I still can't forget the days when I was isolated at home, and I was in a panic and suffering. Fortunately, the national governance is very strong, and residents are strictly required to take precautions, stay at home and go out less to avoid intensive contact and infection.

After more than a year of rectification, the spread of COVID-19 in China has become smaller. However, it is still popular in foreign countries, and the number of infected people is still amazing. The protection policy formulated by the state is stricter, and most people strictly abide by the relevant national epidemic prevention requirements. However, some people are still lucky, and the protective measures are not in place. They treat the epidemic as a joke and eventually get infected.

Residents of a residential area in Changping District were found out, and a family of four and three were diagnosed as COVID-19. The first case is Liu Moumou, the second case is her son-in-law Wang, and the third case is Wang's daughter Wang. The other person in the family is Wang's wife, and her mother has no related symptoms and is classified as asymptomatic.

A family of four and a family of three are diagnosed with COVID-19, and their whole community will definitely be affected. Wang is engaged in aquatic products business. At that time, there were many people in contact with him at the booth. He should not have done a good job of epidemic prevention before he was infected. Many people want to know why Wang's wife has not been diagnosed, which may be due to many reasons.

Second,? Three people in a family of four were diagnosed and one was not infected. There may be many reasons. COVID-19 is highly contagious. If a person is infected, the chances of people around him being infected are very high. But in a family of four in Beijing, three people are infected and one person is not infected, which makes many people feel strange. There may be many reasons.

Wang's wife, Feng, may have strong immunity and protective measures in place, so she was not infected. Take a cold as an example. Some people have good physical fitness and strong immunity, so her chances of having a fever and catching a cold are particularly low. Even if you come into contact with a cold patient, you won't be infected.

Since the outbreak of the virus, the research and development of vaccines is imminent. Later, the vaccine came out and began universal vaccination. It is speculated that Feng has been vaccinated and even injected with a booster. The vaccine played an epidemic prevention role, so she was not infected.

Another reason is that Feng's asymptomatic symptoms are only temporary. You should know that COVID-19 has mutated. It has spread more widely and is more hidden. It has been reported that some people have carried out five or six nucleic acid tests before being tested positive. At first, the isolation time was 7 days, and later it became 14 days. The isolation time is gradually increasing, just to avoid. Duolun nucleic acid test can't detect it.

Whatever the reason, for this uninfected survivor, it is necessary to strengthen control. She needs to be tested in many ways to be sure.

Third,? Not being infected is only a special case, so we must pay attention to epidemic prevention and control. We should not relax our vigilance against epidemic prevention and control just because one or two people are not infected. Just because there are no infected people nearby, you can't feel that there are no security risks. Under the global trend, it does not mean that it is absolutely safe and will not be infected by viruses. Everyone should attach great importance to the prevention and control of the epidemic.

First of all, according to epidemic prevention requirements, you must be vaccinated. When the vaccine first came out, many people thought it would be treated as mice, so they refused to vaccinate. In fact, this idea is wrong. Only when everyone is vaccinated can we improve our immunity to the virus and reduce the possibility of virus infection.

In addition, protective measures should be taken to strengthen personal prevention. Be sure to wear a mask when going out to avoid going to crowded places. Don't go to high-risk areas elsewhere. If you have to go under special circumstances, you must take precautions, report to the relevant departments actively after you come back, and do a good job of self-isolation. Wash your hands frequently and disinfect with alcohol when you go home.

Conclusion: There are four people in a family in Beijing, of whom three are diagnosed and one is asymptomatic. Then asymptomatic people may have strong immunity or the vaccine has worked. Maybe she is lucky, but not everyone will be so lucky. Therefore, it is urgent to do a good job in safety and epidemic prevention, and everyone can't relax their vigilance.
