Does hsv/herpes (not hiv), just herpes transmits from a person whos talking to you and accidentally spit some saliva on a very tiny skin wound that wasnt healed yet on your forearm? again im worried about hsv and not hiv! thanks?

It is possible if the HSV contained saliva is landing on the open wound and saliva with an infected person during an outbreak is more infectious than saliva from a person with latent HSV infection.

About half of the people your age have already been infected with HSV 1 and the only symptom may be occasional cold sore. Even if you are not already infected, what you described is unlikely to transmit HSV-1 Wish you good health!
