Whether it is "one positive" or "two positive", the existence of COVID-19 is an extremely serious threat to human health. Neocoronavirus has been rampant around the world for three years, and people's understanding of the virus is also changing. In this process, there is a noun called "Eryang", which refers to the situation that a person is infected again after the first infection. Recently, there are some reports that people with "two positive" infections are more harmful than those with the first infection. Generally speaking, after a person is infected for the first time, his body will have an immune reaction and produce antibodies against the virus. If the person is infected again, these antibodies will help the body clear the virus faster and relieve symptoms. This is the so-called "two yang". In contrast, when the first infection occurs, the body has not yet produced antibodies, which may lead to more serious symptoms.
However, it is not simple to think that "two yang" is lighter than "one yang". In fact, everyone's physical condition is different. Some people's body will react more strongly to the virus than others, and even "two yang" may have serious symptoms. In addition, some people may have symptoms after a period of time after the second infection, which also makes it difficult for us to accurately assess the harm of "two positive".
From the current data, the population of "two positive" is still lighter than that of "one positive". This is mainly due to the fact that the body has produced antibodies, which makes it easier to eliminate the virus in the second infection. It should also be noted that the elderly and people with more basic diseases may indeed have more serious symptoms when they are infected for the second time, because the immune system of the elderly is relatively weak.
The best preventive measure is to avoid infection as much as possible. Frequent hand washing, wearing masks, keeping social distance and other measures are still crucial. If you have been infected with COVID-19, you should go to a doctor immediately and treat according to the doctor's instructions to achieve a better curative effect. It is also necessary to be aware that even if the infection recovers, there may be "sequelae". These symptoms may last for several months, and we should keep enough vigilance and attention to them.
