I need expert advice on AIDS transmission. I was just googling on how its transferred to others and it was written that its only through blood transfusions, sex and mother to infant. In the myths it was written that it does not transfer through toilet (sitting on toilet). But to be safe i started avoiding toilet as i have boils which bleed on my back and seat. Now please answer my questions below: 1) Say if the toilet looks clean (no blood) can i sit on it . 2) What if it has blood say of infected person. Can i sit on it and still not get infected? 3) Where does the virus live outside . Does it require medium like blood or will it be there on surfaces like door handles or things which we touch daily in offices? 4) I touch so many things outside like doors in a day which are dry and no evidence of blood. Does the virus stick to my hand and when i use my hand to wash my ass, clean throat . Does it enter my body and infect me ??
