So I have a four month LO.

A stranger came up and was talking to me about my LO and without warning shoved her hand into the fingers of my LO

The other thing is that she has a very apparent cold sore.

I immediately held my LO by the same hand, so that it doesn't go in her mouth. I washed her hand, poured sanitizer on it and then went in the pool.

I'm hoping that everything I did made transmission zero risk. But I'm still paranoid.... can anyone reassure me????
