Question: Will returning home to visit relatives during the Spring Festival spread the virus to family members?
Answer: This question can be answered with three dos and three don’ts.
1. Do an antigen self-test . Use the antigen test kit to test yourself twice, and the interval between the two takes 3 to 5 days. If the two antigen tests are negative, there is a high probability that you are not infectious.
Second, it depends on the symptoms. If your antigen is negative and you have no symptoms within 10 days of symptoms, then basically there is no problem. But if you still have very severe symptoms, especially if you have a fever, it is recommended that you not go back. Because even if the antigen is negative, severe symptoms may be caused by other infections, and it is possible to spread these infected bacteria to family members when you return home.
Third, wear a mask. Because you will come into contact with many people on the way home, you may also be infected with other bacteria or viruses in this case.
1. Nucleic acid testing is not necessary. Nucleic acid tests are too sensitive, and false positives often occur, and antigen tests are completely sufficient.
Second, there is no need to do CT. Even if you have had a little bit of mild pneumonia, it does not take so long for the pneumonia to subside. Even if there is a shadow on the CT, it only means that you have pneumonia. It does not mean that you have a virus in your lungs. In the process of slowly repairing, there is no contagious standard.
3. Don’t drop by when you arrive at your hometown. Because you don’t know the infection status and symptoms of other people, there is a high possibility that you are not infected, but your clothes or things may bring those viruses back and spread them to others.
