Random Wikipedia Fact #3

HIV
From Wikipedia, the free encyclopedia


Estimated per act risk for acquisition of HIV-1 by exposure route (assuming no condom use)

Exposure | Estimated infections per 10,000 exposures to an infected source

Blood Transfusion 9,000
Childbirth 2,500
Needle-sharing injection drug use 67
Receptive anal intercourse* 50
Percutaneous needle stick 30
Receptive penile-vaginal intercourse* 10
Insertive anal intercourse* 6.5
Insertive penile-vaginal intercourse* 5
Receptive fellatio* 1
Insertive fellatio* 0.5

Not that I am at all endorsing any sort of risky behavior by any means whatsoever, at all, in any way – but when I found this out a year or so ago I found it quite surprising. Going by these statistics, there is a .05% chance of becoming infected with HIV if a man has unprotected sex with an infected woman, a 0.5% chance if a man is the reciever of unprotected sex by an infected man (the highest of all sexual acts), and a 0.67% chance if you share a needle with an infected person. Mind you, this is per exposure, meaning everytime you do it again the chances double. And when a life-altering and impossibly challenging condition is at stake, you don’t want to be playing any odds. But I think before I found this out I suspected those numbers would be more like 50%, at least for the latter two.
