While there is no cure for herpes, over time symptoms are increasingly mild and outbreaks are decreasingly frequent. Antimicrobial prophylaxis should be of short duration to decrease toxicity and antimicrobial resistance and to reduce cost. It is an infection of the mucous membranes. The manual IsoQuick and automated MagNA Pure and BioRobot 9604 methods provide standardized, reproducible extraction of HSV DNA for LightCycler PCR.

Occasionally, probe binding-site polymorphisms yield “intermediate” melt curves (60 to 62°C); these have been described previously (3–6). So, your inclination to avoid kissing while your husband has a cold sore is a wise move. But, it’s also true that some active virus is present at the site of a cold sore.

To keep the virus from spreading, your husband should be careful to avoid kissing and other skin-to-skin contact with you and with anyone else while he has a cold sore.
