Nucleic acid test ct values in the 30’s require treatment if they are generalized or severe, and intensive isolation is the mainstay for mild and asymptomatic infections. According to the ninth edition of the guidelines for the management of neocoronavirus pneumonia, a nucleic acid test CT value of less than or equal to 35 is defined as an infected person, so if it is 30, the diagnosis of infection is clear. If accompanied by a clear case of neocoronavirus pneumonia or a critical condition such as respiratory failure, the case is classified as generalized or severe and requires intensive hospital isolation. However, if there are no clear symptoms, or only mild symptoms such as fatigue, they are mild and asymptomatic infected persons, and are now mainly isolated centrally, with auxiliary treatment with proprietary Chinese medicines such as Lianhua Qingdian capsule, and will only be transferred to hospitals for treatment if there is an aggravation of the symptoms, and most of the patients with mild symptoms can be cured on their own.
