live in apartment with another man ( I know he has some unprotected encounters ) I was confused that ,just before writing this question I took shower and I afraid I may accidentally left my tooth brush and use his tooth bruth alalso the colours are different , what ever , I think the time between him and me to take shower about 5 mintues to 7 mintues . and of course his tooth brush washed by him after his shower coz that as I remmeber ( it was clean , with it is own colour no signal white system ).
My questions here ? If I wrongly used his tooth brush :
1- Is that risky ?
2- What maximim tirme That HIV lived out side the human body ? ( of course water applied to his tooth after finished as usuall ) , Is that will kill or help to reduce HIV if present ?
3- I tested my toothbrush after while it was little wet , so that may proof I used mine ( not use water rush or I mean no wet ness from my shower ).
4- Is hepatitis B & C can transmitted this way .
Again thanx , for your comments and replies .
