Recently, many people have not only developed a fever but also suffered body aches after being infected with the new coronavirus. It even reminds some women of their own childbirth pains. The reason why the body is like this is actually not a bad thing.
The immune system is composed of countless immune cells, organs, and systems. When a virus invades the body, the immune system can quickly detect it, locate, disinfect, and remove the invader, so the body has a painful reaction.
The increase in body temperature is caused by the white blood cells in the immune system engulfing the virus. Muscle aches throughout the body are caused by the body concentrating all its strength to deal with the virus, causing the muscles in some parts of the body to lose strength support, resulting in a feeling of weakness and soreness.
The reason why you will have a fever after being infected with a virus is not caused by the virus, but is proof that the immune system is activated and fights against the virus. Faced with this situation, you cannot let it go. If the high fever persists, it is a wise choice to take antipyretics.
How long will it take for the new coronavirus to become negative without infecting others?
Take medicine to relieve physical discomfort. In about a week, the body will slowly return to its previous state. So people who are positive want to know whether they have recovered. There are two main judgments.
. Self-test whether the symptoms of COVID-19 have been relieved.
After being infected with COVID-19, whether the body's fever, cough, aches and other symptoms have been relieved and remained stable for more than three days, mainly if the body temperature has been normal for more than three days. If necessary, you can do a chest CT examination.
2. Is the nucleic acid test result negative?
If you feel that there is no problem with your body, you can go for a nucleic acid test. If two nucleic acid tests are done 24 hours apart and both are negative, you can be considered recovered.
If it is not convenient for you to do nucleic acid testing, you can do antigen testing for three consecutive days. If the antigen test shows negative, it means you have recovered.
After meeting the above two requirements for recovery, you will no longer be contagious. Under normal circumstances, it takes 7 to 10 days to recover from COVID-19.
If the body's immunity is relatively good, the physical symptoms will improve on the fifth day of infection, and there may even be no symptoms. However, the virus is still contagious at this time, but the number of viruses in the body has decreased.
If you go to work after 5 days, you must wear a mask for the safety of others. If you work in hospitals, nursing homes, shopping malls and other places with high traffic, it is best to isolate yourself at home for 10 days before going to work. Generally, you will not infect others.
After recovering from infection, how long will it take to become positive again?
After recovering from COVID-19 infection, it is still possible to become positive again. Clinically, it is found that some patients have intermittent detoxification, and the nucleic acid test results will be considered to be positive after turning negative.
In some cases, if the patient suffers from underlying lung disease or has a relatively high viral load, he becomes negative after recovery from treatment, but becomes positive again after treatment is completed.
Re-positive cases are relatively rare, but they do occur. This is because the inactive virus of the new coronavirus has not been completely eliminated in the body. Generally, recovered positive patients will not become critically ill and will not be contagious.
After the patient turns negative, he should also strengthen health management and closely observe his physical health. In order to avoid the recurrence of the virus, the patient's clothing, bed sheets, towels, tableware and other daily necessities should be isolated as much as possible.
