It is not necessary to test nucleic acid every day, but once a week can better evaluate whether there is Covid-19 infection.

Nucleic acid detection has a good etiological value for evaluating virus infection. Usually, we should pay attention to rest, go to crowded places less, and exercise properly to improve our immunity. COVID-19 vaccination has certain preventive value for related virus infection.

If there are no corresponding contraindications, you can be vaccinated to prevent it. Usually, you should pay attention to developing good sleep habits, strengthening nutritional support, eating more foods rich in vitamins and high-quality protein, and paying attention to regular physical examination to develop good exercise habits. Nucleic acid testing doesn't have to be done every day, but it should be decided according to the situation in each region.

1. Low-risk areas

In novel coronavirus-infected areas which are relatively stable, such as low-risk areas, it is not necessary to carry out nucleic acid detection every day, so as to avoid wasting national resources. Wash your hands more at ordinary times, wear a mask when going out, and don't go to crowded places. Proper exercise can improve your immunity and you can exercise according to your physical condition.

2. Middle and high risk areas

At present, the purpose of nucleic acid testing is to detect novel coronavirus infection. For middle and high risk areas, nucleic acid testing must be carried out within 24 hours, which can effectively prevent asymptomatic infected people and some mutant strains, thus reducing the spread of novel coronavirus. In addition, there are many people in the place where nucleic acid testing is conducted, so you must wear a mask and do personal protection. Wear it immediately after collecting nucleic acid samples, and wash your hands and disinfect after nucleic acid testing.
