At present, COVID-19 is raging all over the world, and many people will be infected with COVID-19 and become positive. After being infected by COVID-19, they will recover. If they are infected with COVID-19 again, it is called secondary infection or reinfection. At present, the COVID-19 we are infected with is usually Okmijon virus. If new mutant strains appear in COVID-19, we are still at risk of being infected with COVID-19 virus again.
At present, patients infected with Okmiqiong virus generally have symptoms such as fever, muscle and joint pain, runny nose and sore throat. Some may have difficulty breathing and shortness of breath. Generally, the fever will be above 38.5℃ for more than 3 days. Many patients with basic diseases are seriously ill and unable to control their medication. If you want to see a doctor in time, some people may have symptoms such as drowsiness, vomiting, diarrhea, refusal to eat, and pregnant women may also have symptoms such as headache and dizziness. These have seriously affected our daily life and work quality. Through research, scientists found that Omicron virus, Delta virus or original virus will not be reinfected by the new strain soon after recovery in Yang Kang, and the probability of reinfection of the same strain is particularly low. Even if it is an infection, there will be no serious phenomenon, generally mild.
If a new mutant strain appears in COVID-19, we will be infected by COVID-19 again. If we are infected with the virus again in a short time, the chance is very small, and the illness will be lighter when we get sick. On the contrary, if we are infected with the virus again for a long time, the chances will increase and the condition will be very serious. This is because of the function of immunity in our body.
Generally speaking, our body's immune protection ability is three to six months. The same mutant in COVID-19 belongs to "close relatives". For the same mutant, our bodies are immune-protected, that is, we are infected with different viruses in COVID-19, and there will be cross-similarity between the viruses. After we are reinfected, our illness will be lighter, and we will gain some immunity after being infected with the virus once, just like we were vaccinated once.
Cornell's epidemiological study found that serious secondary infection is very rare, with only 0. 1% chance of serious illness and no criticality.
COVID-19 will continue to mutate. After Yang Kang, it will still be infected with new strains again. Lifelong immunization is impossible, but the probability will be much lower. After COVID-19 recovered, he should wear a mask, wash his hands frequently, pay attention to disinfection, open more windows for ventilation, and continue to do personal hygiene protection to avoid re-infection.
Remind everyone that you must exercise at ordinary times, and only run and exercise more. Only in this way can you make your body healthier and enhance your immunity. In this way, we will not be infected with COVID-19 virus, which will make our bodies healthier, stronger and better resistant to the virus.
