The number of new coronavirus infections has increased significantly in the country, and various discussions on the Internet about the secondary infection of the new coronavirus have also attracted everyone's attention.
What is secondary infection?
Generally speaking, secondary infection (re-infection) with COVID-19 refers to a situation where a person is infected with COVID-19 and then becomes infected again after recovering.
Even if you have been infected with the new coronavirus, there is still the possibility of reinfection, but the probability will be reduced, but you still cannot take it lightly. Secondary infection is usually symptomatic, and the CT value of the nucleic acid is relatively low, viral load is high, and it is contagious.
If the nucleic acid test is positive more than one month after recovery, the possibility of reinfection is relatively high. "Judging from the time when secondary infection occurs, there is generally an interval. It cannot be said that secondary infection will occur soon after infection. The probability of secondary infection with the same strain is extremely low."
What is the rate of repeated infection? The probability of secondary infection of
is mainly related to the level of human immunity and the variation of virus strains. The higher the immune response indicators such as antibodies are, the smaller the variation of virus strain will be, and the lower the incidence of secondary infection will be.
Secondary infection refers to the phenomenon that after a certain time span, the infected person reappears new coronavirus symptoms and the amount of virus in the body rebounds after recovery.
Compared with those who are re-positive, the amount of virus in the body of re-infected people is relatively high. The CT value is generally lower than 35, while the CT value of re-positive people is generally higher than 35. Current research shows that compared with early mutant strains, the secondary infection caused by Omicron is slightly higher, but overall, the probability of secondary infection with the new coronavirus in a short period of time is still relatively low.
Will a second infection with COVID-19 be more serious?
A second infection with the new coronavirus will not necessarily be more serious. The specific severity of the disease after a second infection with a new coronavirus variant is usually related to the virulence and quantity of the virus, the body's own immunity and the presence of underlying diseases, among other factors. Researchers call on people who have already been infected with the new coronavirus to continue to be vigilant to reduce the chance of repeated infection. The new coronavirus continues to mutate and may still pose a threat for years or even decades.
According to data, compared with patients who have only been infected with the new coronavirus once, if there is a repeated infection, the risk of death will more than double, the risk of lung diseaseheart disease, and the risk of hospitalization will be three times higher.
How to avoid being infected with COVID-19 again:
First: Get another shot of COVID-19 after half a year Booster shot
Li Tong, an expert at Beijing You'an Hospital, once said that there are various types of new coronaviruses, and different new coronavirus strains may cause secondary infections. After this infection is cured, we will receive another shot of the new coronavirus booster vaccine in half a year.
Second: Wear a mask as required when going out
If you need to go to crowded places, such as schools, hospitals, shopping malls, etc., you can choose to wear a mask, which can prevent the spread of the new coronavirus through droplets.
Third: Eat hot food
(cook meat and eggs thoroughly when cooking), drink hot water, work and rest regularly, pay attention to physical exercise and nutrition, and improve your own immunity.
Fourth: Improve your own immunity
The secret to staying healthy is exercise and exercise. Exercise not only helps to stay healthy, but also makes our body more relaxed and in a healthy state. Exercise also helps to improve human immunity. More exercise will reduce the probability of getting sick.
How to improve immunity?
1: Ensure a comprehensive and balanced nutritional intake to maintain the body's nutritional needs and trace element needs, because many trace elements are related to the body's non-specific immune function . Once trace elements are lacking, immunity will decline.
2: It is recommended to drink more than 2500ml of drinking water every day, preferably about 3000ml. By drinking more water and diuresis, you can promote the balance of the internal environment in the body, increase the basal metabolic rate, and increase immunity.
Three: Pay attention to increasing sleep. Sleep is the first major supplement for the human body. Through sleep, the body can be effectively repaired, the body's immune function can be improved, and the liver's detoxification can be promoted at night.
