hello people, i have very special and maybe stupid question. today when i was coming back home with my little son, there was a blood on the doorknob of the appartmenthouse we live in. we both touched it and i realized too late. my son is quite small, year old, only started to walk short time ago, and has small scratches everywhere,... is it possible to contract hiv this way? (touch the blood and then the cut, put hand in the mouth, in the eye,... he keeps doing this all the time). i dont know if there is any difference if this is in the case of small kid. i also has cut on my finger, not too big, but.. anyway. i am stressed about it. the blood was fresh, several drops of it on the doorknob and door. thank you all very much.
