Person A has herpes simplex virus and has an active cold sore/fever blister. Person B also has herpes (as does 80% of America, by some estimates) but no active outbreaks at the moment, nor has B had any for several years.
A and B kiss, and B develops a cold sore/fever blister soon thereafter. It would seem to me that as a herpes carrier already, B wouldn’t be susceptible to an outbreak from contact with another herpes carrier.
Question: As B already has herpes, is the cold sore development a result of the kiss with another herpes carrier? Or is it just coincidence, or perhaps even psychosomatically induced? Are there maybe different strains of the herpes virus that B just wasn’t used to, hence the outbreak?
