Nucleic acid detection can be carried out regularly. This is not only a good protective measure for us personally, but also for the safety of others. We can carry out nucleic acid testing within one week after going abroad and returning to China. If you don't go out, walk around your home and company, and have a nucleic acid test every half or one month on average. The purpose of doing this is to ensure your real safety and also to protect the safety of others. And now nucleic acid testing is very cheap. The mixed sampling price of some 3A hospitals is only in 8 yuan, and the single sampling price is only about 10 yuan.
Be sure to have more ventilation at home and prepare some disinfectant or solid alcohol. After working outside during the day, people must get rid of all bacteria before going home. You can prepare a bottle of solid alcohol or disinfectant on your body. People who are often at home should keep them at noon or afternoon every day. Window ventilation time should not be less than two hours. Secondly, some clothes and bedding carried with you should be cleaned and replaced in time. The most important thing is to wash your hands frequently.
Try not to go to public places when you go out and keep your distance from others. When people go out at ordinary times, they must be careful not to go to high-risk or medium-risk areas unless necessary. If they want to go to public places, they must avoid the rush hour. For example, when they go shopping in the mall, they can choose from 3 pm to 5 pm or from 10 am to 12 am. There are fewer people in public places, especially at night, so try to avoid going to public places at this time and keep your distance from others when you go out. The safe and effective distance is more than one meter, followed by wearing a mask.
