Hello.
Genital herpes is a condition which is caused by Herpes Simplex Virus (HSV) Type 2 or 1 . When you take anti virals, the skin lesions get resolved. However, the virus tends to stay dormant in the nerve roots. It can resurface and cause similar lesions at a later date when the body is undergoing some stress. The frequency of this recurrence and severity can be reduced when a complete anti-viral drug course is taken during the first outbreak. So please go ahead and take it.
Please let me know if you have any queries.
Take care.
