I have hsv-1 what is the chance that I could transfer the virus to my bf, when I have no cold sores present?

Up to 50% Half of all people have hsv1 by the time they go to college. So there is a 50% chance that your boyfriend already has it and there is no issue about passing it to each other. Even without an active cold sore, there is some asymptomatic shedding that occurs always, so you can pass it to him even if you don't have cold sore if he is negative for hsv1.
Not likely. You may not be aware that you have lesions present but if there are no lesions and not vesicles you are not contagioius... It is important to avoid contact with mucous membranes that are infected if lesions are present and routine hygiene like hand washing is critical.

Since cold sores are so common and probably easy to pass on to babies, how would you know if a baby contracted the HSV 1 virus?

Herpes simplex. Common. Between half and three-quarters of ordinary people "carry" HSV. Most are not symptomatic. If you have a mouth or lip blister , I wouldn't kiss the baby, but I wouldn't recommend 1/2 to 3/4 of mothers not kiss/touch/cuddle their babies. You probably would not know unless the baby was extremely young, unusually small or very ill. Read more...

My boyfriend of a year has a herpes cold sore on his lip and he says he has never had it before. I don't have the virus. Can hsv-1 be dormant for years and suddenly outbreak?

Absolutely. Most people are infected with oral hsv as children and can indeed lay dormant for years and then emerge. You may even have it and not realize it, unless you have had antibody testing that is negative. Also, oral herpes and genital herpes are two separate viruses so this doesn't necessarily mean that he has been unfaithful or performed oral sex on someone else or anything of the sort. Read more...
