According to reports, asymptomatic patients with neocoronavirus are those who have no self-perceived clinical symptoms such as fever, cough, and sore throat, and have no clinically identifiable symptoms and signs. However, pathogenic tests for neocoronavirus in respiratory specimens are positive.
From the perspective of detection, asymptomatic infections are mainly detected through active surveillance. There are four main ways. First, medical observation of close contacts; second, investigation of aggregated epidemics; third, tracking of the source of infection; fourth, some have Personnel with history of travel or residence in areas where neo-coronary pneumonia cases continue to spread at home and abroad will be tested.
