Asymptomatic infection with Neocoronavirus means that the nucleic acid test is positive for Neocoronavirus but no clinical symptoms appear, and there are two scenarios for this phenomenon. In the first case, although the nucleic acid test is positive, the infected person never has any symptoms during the medical observation period, and the nucleic acid test result also becomes negative during the observation period, and the infected person is asymptomatic from the beginning to the end. In this case, the patient is basically self-cured. The second situation is that the nucleic acid test of the new coronavirus infected person is positive, and there were no symptoms before that, but during the observation period, a series of clinical symptoms such as fever, cough, fatigue, sore throat, myalgia, nasal congestion, runny nose, etc. appeared, which means that it has been in the incubation period before there are no symptoms. However, it should be noted that in either case, asymptomatically infected persons with New Coronavirus are a source of infection and need to be placed under centralized medical observation to prevent mass transmission of infection. Considering that people with asymptomatic infection of the new coronavirus have no symptoms in the early stages, they are often more likely to be infectious, and it is recommended that they actively undergo nucleic acid testing, wear masks when traveling and stay away from crowds for effective protection.
