While biologically possible, oral HSV-2 itself is rare and when it is present orally, it is rarely shed from the mouth. I’m not sure what you mean by high-risk setting but the facts about oral HSV to remain. If it would reassure you more to have a western blot done, you can certainly do that. Sometimes it isn’t the medical possibility of an infection that guides a decision to do a better test but rather the need for peace of mind. That’s your call.
