l How to judge oneself already recovered?

First, the symptoms should improve, such as normal questions for more than three days, respiratory symptoms disappear, or when significantly relieved. If there is pneumonia, the CT lung lesions also began to absorb better. Another is two nucleic acid test negative, these two to interval more than 24 hours, or accounting CT value is greater than or equal to 35, so accord with the negative conditions.

l Is there any infectivity after turning negative?

At present, we believe that if the above conditions are met, the infectivity will be very low.

If you still have cough symptoms, it is recommended that you wear masks when returning to work and going out to visit relatives and friends, especially those who work in important posts such as nursing homes and medical institutions. If you want to visit the elderly, infants, and young children, it is better to meet the conditions for turning negative at least 10 days after the onset of the disease, so that you can basically think there is no problem.

l Easy to infection within two weeks after recovery?

We often say that the specific antibodies, two weeks to reach a relatively high level, or we can detect the level. But actually the moment the virus enters our body, the immune system is already at work. The subsequent production of protective antibodies peaked at two or three weeks for a long time, but it does not mean that we had no protection within these two weeks. At this time, if there is really a virus in the body, it can be quickly removed, but it is relatively not easy to infect. So there is no saying that two weeks, which is not accurate.

l Can recovery personnel take care of other positive family members?

After the infection, he was immune to the virus and would not be reinfected again, so he could go to take care of other family members.

l After someone recovers still feels chest tightness and short breath weak is how to return a responsibility?

Many people will have a high fever, systemic muscle soreness, fatigue, sweating, headache, sore throat, and other symptoms, so after this disease, there are some people will continue to have this body weakness, or even some symptoms of chest tightness, usually this can be relieved within two weeks. If you think you're still not very good, you can rest for a few more days. Do not just recover, immediately engaged in very heavy work, or immediately go to strenuous exercise, fitness, or step-by-step, once found tired out of the sweat of these problems to rest in time.

l One COVID-19 infection is equal to a COVID-19 vaccine?

It can't be infected instead of a vaccine, but it can act as a vaccine so that we won't get infected for a short time soon. But that's not that we can fly after being infected once. The virus is still mutating, and it is cross-protection against the trading strains of the virus, but if the virus continues to mutate, or some more distant strains, our risk of infection will increase.

l Which people are more likely to have a second infection?

Immune-compromised people,

such as the elderly and infants under the age of three. The immune function of the elderly is degraded, and the protective maintenance time after infection recovery is relatively short;

The immune function of infants under three years old is not perfect, and the protective maintenance time after recovery may also be relatively short.

Immunocompromised people, such as AIDS patients and users of immunosuppressants, also have a relatively short duration of protection and a greater risk of secondary infection over time. People in high-risk positions, such as medical staff, public transportation operations, and maintenance personnel, usually have more contact with people and have a high risk of infection.

l Is it possible for a person to have multiple infections because of different strains?

It's true. Someone may have been infected once with the original strain, once with the Delta strain, and once with the Ojon strain. Because each infection provides some protection, the risk of reinfection becomes smaller, and the symptoms after the reinfection will decrease. In general, don't worry too much about future reinfection.
