Omicron is more contagious, and it is particularly critical to find the source of infection in time, control the source of infection, and cut off the transmission route.
Three types of antigen testing are suitable for people: Firstly, those who go to primary medical and health institutions for treatment, with symptoms such as respiratory tract and fever, and have symptoms within 5 days; Secondly, community residents who need antigen self-testing; Thirdly, people who feel that they are at risk of infection.
When the epidemic situation is relatively tense, once symptoms such as headache and fatigue appear, many people feel very uneasy. If you are worried about contracting the virus, you can use the antigen detection method at this time.
Besides, the frequency of antigen testing is once a day, and it does not need to be too frequent.
