What are the symptoms of novel coronavirus?

Asymptomatic infection refers to people infected by COVID-19 who have no clinical symptoms (such as fever, cough, sore throat, etc.). ), but the respiratory tract and other specimens were positive for novel coronavirus etiology or serum specific IgM antibody.

Strict management measures should still be implemented for asymptomatic infected people. Asymptomatic infected persons should be isolated for 14 days. After the expiration of the isolation period, if the nucleic acid test is negative for two consecutive times, the isolation can be lifted in principle. If symptoms appear during isolation, you should be admitted to hospital immediately.

Asymptomatic infected people are mainly found through close contact screening, cluster epidemic investigation and source tracking investigation. A few asymptomatic infected people may develop into confirmed cases, but most of them will heal themselves.

Asymptomatic infected people can also become the source of infection, with a certain risk of transmission. At present, the treatment of asymptomatic infected people is to isolate them when they are found. During the isolation period, they will continue to carry out nucleic acid testing to further observe whether there are symptoms, and they can also use some antiviral drugs to intervene. In principle, isolation can only be lifted after two consecutive negative nucleic acid tests.
