is a contagious std
which is at its most contagious when you have active lesions.
When lesions are not present, the disease can still be contagious but less so. Things that can reduce the odds of spreading to your partner are avoiding sex
with active lesions, using anti-viral suppressive meds daily (your doc can help with this) and condoms
, but nothing is perfect. Try www.Herpes.Org for info.
