Abstract: A method of treatment is disclosed for herpes infections of external tissues and method of preventing the occurrence of blisters and ulcerations in herpes disease in humans. The method consists of directly injecting small treatment amounts of suitable antiviral agents, e.g., acyclovir, ribavirin, or vidarabine (ara-A), within the specific time period of first 36 hours after the appearance of detectable manifestations of external-tissue infection or any of the prodromal symptoms of burning pain, itching, tingling, swelling and erythema or combinations thereof. The treatment amounts of antiviral drugs per day used in this invention are very small compared to the dosage amounts used by prior art calculated based on kilograms of body weight per day. The antiviral drugs so injected will kill the virus quickly in the skin or mucus membrane, or inhibit its replication or otherwise render the virus inactive before the virus will have time to multiply and form the blisters and ulcerations.
