1. Academician Zhong Nanshan revealed that the sequela of COVID-19 is determined by the number, virulence and human immunity of pathogens. Academician Zhong Nanshan once said that there are two reasons, one is whether people will get sick after being infected with pathogens, and the other is the severity after getting sick, which is the result of the combined action of the number, virulence and human immunity of pathogens.
Second, from the words of Academician Zhong Nanshan, we can know whether there are sequelae after COVID-19's infection. The toxicity of 1. COVID-19 is one of the important reasons for the sequela of COVID-19 infected with COVID-19.
In the early days of the COVID-19 outbreak, the original virus strain was very toxic, and after suffering from COVID-19, there were usually sequelae. After repeated mutation, the toxicity of COVID-19 showed a decreasing trend, from mutant α, β and γ to mutant δ and then to mutant Omicron. The same infection in COVID-19, compared with two years ago, now the possibility of sequelae will be greatly reduced.
2. Human immunity is the second important cause of post-infection sequelae of COVID-19 in COVID-19.
People will not be angry when they are sick. Similarly, in COVID-19, when the immunity is low, the harm caused by the virus will also increase. For example, elderly patients with weak constitution and patients with other diseases are not only more likely to be seriously ill after being infected with COVID-19, but also have a longer recovery time and a greater chance of sequelae.
After a long time, some people will ask, what is immunity? Immunity is the defense mechanism of human body, the ability of human body to identify and destroy any foreign body (virus, bacteria) invading from outside, and the ability to ensure people's health and longevity.
What we have to do is to find ways to improve our immunity. 1. The first thing to stay away from COVID-19 is not to be infected by COVID-19.
In order to avoid COVID-19 infection to the greatest extent, we should stay away from virus-infected people. For example, we must abide by various epidemic prevention regulations, especially when there is an epidemic around us. At the same time, personal epidemic prevention measures such as wearing masks, avoiding gathering and paying attention to hygiene should be taken.
2. Vaccinate with COVID-19 vaccine.
Improving immunity includes two aspects: artificial active immunity and autoimmune. Vaccination with COVID-19 vaccine belongs to artificial active immunization. Why is the mortality rate and mortality rate greatly reduced after infection in COVID-19? Because most of us have been vaccinated with COVID-19 vaccine, those who can be vaccinated but have not been vaccinated with COVID-19 vaccine must be vaccinated as soon as possible.
3. How to improve your immunity?
Improving immunity should include at least four aspects:
First, exercise.
Exercise can promote blood circulation, accelerate metabolism and enhance the functions of various organs. When the functions of various organs are enhanced, the physical quality and immunity will be improved.
Second, a reasonable diet.
The intake of high-calorie foods such as high fat and high sugar, and the eating habits of overeating are easy to make people obese. Obesity is a disease, which can also lead to other diseases. A reasonable diet should pay attention to the balance of nutrition.
Third, have a good rest.
If you don't have a good rest, your skin will be bad, your mental state will be bad, and your immunity will decline; To have a good rest, we should not only combine work and rest to ensure sleep, but also try to rest according to the biological clock.
Fourth, keep a good attitude.
When you are depressed or fidgety for a long time, not only can you not eat well, sleep well, but your immunity will also decline. Therefore, when you are not infected by the virus, you should pay attention to adjusting your mentality. After being infected by the virus, you should adjust your mentality.
