An asymptomatic infected person with Neocoronavirus is infected with Neocoronavirus without showing any clinical symptoms. They may be in the incubation period, or they may remain asymptomatically infected. 1. Incubation period: This is when the patient is in the incubation period of the disease, when there are no clinical symptoms, but nucleic acids can already be detected. Symptoms may appear during the medical observation period and become a confirmed case of CKP. 2. Asymptomatic infected patients: Asymptomatic infected patients of the new crown virus are those who have detected the nucleic acid of the virus, probably due to the better physical condition of the patients, and have not been clinically manifested during the medical observation period. In addition, the nucleic acid of the new coronavirus may become negative before the observation period is lifted. Regardless of which of these situations the patient is in, asymptomatic infections with the new coronavirus require intensive medical observation, and if symptoms develop, they are treated as patients with new coronavirus infections. Note: The terms “new coronavirus pneumonia and new coronavirus pneumonia” mentioned in this article were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
