blood on pants

[ridge_y]

Reading this forum has relieved a lot of worries of mine. But I'm still haunted by a recent incidence. I really hope the experts can ease my irrational mind. Two weeks ago, I was told by someone that I had a large blood spot in the back of my pants near anus area. I had no idea of where it came from. I was on a business trip at Beijing, and I only sat in restaurant, taxi, hotel, and office buildings. I know that blood cannot transmit HIV if my skin has no opening. But what worries me is a mild hemorrhoid problem. I don't recall if there was any fissure near the anus. Sometimes when I wipe BM, there are some blood traces -- that's the extent of my hemorrhoid. Now I worry if this unknown blood may enter via my anus hemorrhoid. It has been haunting me since it happened. I know that a testing may put my mind at peace, but it is too early to do a test.

Doesn't matter how fresh it was you never had an exposure.

HIV is transmitted by;
Unprotected penetrative anal and/or vaginal sex
Sharing works with other IV drug abusers
Mother to child

Thanks for the comment. But what if the blood is fresh. For the pants to catch so much blood, there must be a large amount of fresh blood in contact. I'm very concerned with how "fresh" is infectious.

HIV is unable to reproduce outside its living host (unlike many bacteria or fungi, which may do so under suitable conditions), except under laboratory conditions; therefore, it does not spread or maintain infectiousness outside its host.
