After you get positive blood test for herpes does the doctor need to see the lesions every time you need medication throughout the year?

Depends on provider: For most adults with a chronic recurring issue like this I would expect to be seen at least once to twice a year. A refillable prescription for the appropriate medicines would be routine as long as the regular followup was done. Others might have a different approach. Much of these patterns are driven by the standards set by the medical boards.

See below: Agree with Dr. F. Once or twice a year examination should suffice. Please note that you can transmit infection even if there are no visible lesions. You should tell your sex partner about your infection. Have a healthy diet, exercise, drink plenty of water, have safe sex, and get HPV vaccine. Wish you good health!
