How do you if you have herpes prevent giving it to someone else?

Prevention: There is no cure. We can only treat it. Patient is always at risk of sheeding even if asymptomatic. Incubation period could be 2-12 days, in some cases up to 26 days. The only way to avoid std is by abstinence. Latex codom is just a barrier to prevent std, patient can still get or transmit std when wearing a condom. Partner needs to see a doctor.
