Currently, mild cases of novel coronavirus pneumonia can heal spontaneously because many viruses themselves, including influenza viruses, are somewhat self-limiting. Although there is no vaccine against novel coronavirus pneumonia and there are no specific antiviral drugs, novel coronavirus pneumonia is self-healing and the body may produce IgG and IgM related immunoglobulins, i.e., related antibodies, for treatment, such as using plasma containing high concentrations and titers of antibodies from recovered patients for adjunctive therapy. Currently, the treatment of novel coronavirus pneumonia is limited to general treatment and symptomatic treatment, so it is mainly treated by autoimmunity or imported antibodies, while for mild cases it is entirely possible to heal on its own.
