Herpes simplex virus is a common cause of infection.

Herpes simplex virus infection is the first choice of antiviral treatment, but the specific dosage and course of treatment vary according to the course and clinical manifestations. Its symptoms themselves are not serious, so many times even if not treated, as long as a period of time can also heal. But when the immune function is low resistance or suffering from other diseases, herpes simplex is easy to attack in this case. Therefore, for incipient herpes, it is recommended to take antiviral drugs, usually for 7 to 10 days. If recurrent herpes should be actively treated; if herpes simplex attacks more than 6 times a year, or even 10 times, it is necessary to take viral suppression therapy for treatment. Antiviral drugs must be taken every day for 4 to 6 months, or even longer.
