Whether an asymptomatic infected person needs treatment is related to the type of pathogen he or she is infected with and cannot be generalized. Asymptomatic infections refer to carriers of pathogens that are produced and reproduced in the body and that can be excreted from the body, but do not show appropriate clinical symptoms. Among the common asymptomatic infections, such as the new coronavirus and hepatitis B virus carriers usually do not require special treatment, but patients with viral hepatitis C and AIDS, although they are asymptomatic infections, still require treatment. Asymptomatic infected people are infected with bacteria, fungi, viruses and other pathogens, and are carriers of pathogens with no obvious symptoms, but are contagious. Therefore, if a patient is found to be suffering from an asymptomatic infection, there is no need for treatment, but he or she should be isolated and put under medical observation in time to avoid contagion.
