Adults can also get HFMD, but most do not have symptoms because adults have a better immune function. However, some adults with poor immune function can also develop obvious symptoms of HFMD, such as a rash and fever. The rash may be on the hands, feet, mouth, and other places, and it can form a source of infection that can cause infection in surrounding children and other adults. Adults can get HFMD and usually have no symptoms, but it can be transmitted to children. HFMD in adults is treated symptomatically and does not require antiviral treatment unless more severe comorbidities are present. Herpes in the mouth can be treated symptomatically with ribavirin spray, rehabilitative new liquid, stomatitis spray, etc. After the herpes breaks down and becomes infected, anti-infective creams such as fusidic acid sodium ointment or anti-infective drugs can be used for symptomatic treatment.
