Some patients with neocrown pneumonia are asymptomatic and are referred to as asymptomatic patients, i.e., no clinical manifestations of fever, malaise, or cough, and CT is normal, but nucleic acid testing of nasopharyngeal swabs is positive and significant in terms of transmission. The respiratory tract carries the virus and exists as an infectious agent. Because there are no clinical manifestations, no special treatment is needed. There are no specific antiviral drugs available. For asymptomatic patients, antiviral therapy and other treatments are not required, but separate isolation and observation are needed.
