I've had Oral HSV1 for as long as I can remember. I've been diligent in preventing transmission to my one year old son by practicing proper hygiene and not kissing him. However, I cosleep with him and last night he woke up briefly and while comforting him, I gave him a peck on the cheek. This morning I discovered I have a cold sore on my upper lip and it's swollen and there is a visible blister underneath the skin, and appears to be advanced (like what a cold sore looks like on day two of an outbreak). It's not oozing at all. But I'm flipping out because like I said, it looks advanced. What are the odds I gave herpes to my son?! Thank you so much!
