Which viral infection is typically treated with an antiviral agent given as a topical cream?

The treatment of herpes simplex virus (HSV) infections often involves the use of topical antiviral agents, such as acyclovir cream. HSV can cause localized lesions, such as cold sores or genital herpes, which can be effectively managed with these topical formulations. These topical treatments work directly at the site of the infection, providing targeted relief from symptoms and helping to reduce the duration of outbreaks.

In contrast, other viral infections like influenza are usually managed with systemic antiviral medications that are taken orally or injected, rather than applied topically. Similarly, Human Immunodeficiency Virus (HIV) and Hepatitis C require systemic treatment regimens involving antiretroviral or antiviral drugs that affect the entire body rather than localized treatment approaches. Thus, the use of a topical antiviral cream is particularly relevant for managing infections caused by the herpes simplex virus.
