New crowns of asymptomatic infections usually resolve spontaneously in about 7 to 14 days, but some patients may not.
An asymptomatic New Crown infection is one in which the infection is positive for New Crown virus nucleic acid, but there are no obvious symptoms. Asymptomatic infected patients usually recover spontaneously in about 7~14 days, while some infected patients turn into mild or common type patients who need further treatment.
Ordinary, severe and critical cases of novel coronavirus disease usually do not resolve on their own. Symptomatic treatment, such as treatment for fever, sore throat, cough and other symptoms, is needed for these patients.
After diagnosis of neocoronavirus infection, isolation is necessary even if there are no symptoms. Usually, two consecutive negative nucleic acid tests are required before the patient can be released from isolation.
