Most of the herpes that appears on the finger area belongs to herpes simplex, and the virus that infects this herpes is mainly herpes simplex virus type 1. This disease can be treated with the same principles as other areas of herpes simplex, with topical antiviral creams, such as topical acyclovir ointment or penciclovir ointment. Oral antiviral medications, such as acyclovir tablets or valacyclovir, can also be taken orally. If the herpes is accompanied by localized vesicles, topical zinc oxide cream can be applied to prevent further expansion of the vesicles. In addition, topical spraying with Rehab can be used to promote the healing of local vesicles or wounds. During the treatment period, it is also necessary to pay attention to local wound cleaning to prevent secondary infection.
