>I like Charlie Sheen’s Chances

>I was putting together a little presentation on post exposure prophylactics and HIV and came across the transmission rates for exposure to a person known to be infected with HIV and found the numbers to be surprisingly low. My first thought was, if that’s true, there must be a LOT of people making a LOT of stupid decisions out there to cause 40,000 new cases of HIV each year. But its good to be aware of these number, as several times this past year a patient has asked me how likely they are to catch HIV with their particular given risky practice of choice.

Below is the risk per 10,000 exposures to an infected source.

9000 – Blood transfusion
67 – Needle sharing injection drug use
50 – Receptive anal intercourse
30 – Percutaneous needle stick
10 – Receptive penile vaginal intercourse
6.5 -Insertive anal intercourse
05 – Insertive penile vaginal intercourse
01 – Receptive oral intercourse
0.5 – Insertive oral intercourse

The above number assume no condom use. So if Charlie Sheen goes around and has unprotected sex with 10,000 infected porn stars (which I am sure is a number he is rapidly approaching), he has only a 5/10,000 chance of becoming HIV+. That number just seems remarkably low to me, but hey, good for Charlie.

About ER Jedi

I’m a resident doctor in Emergency Medicine and I’ve learned during the past few years that 1) I’ve had some pretty amazing experiences 2) I have a very bad short-term memory. So this blog is just a place for me to write about some of these experiences, from the ER, medical school, the wards and life in general. At least that way I’ll have some idea as to where I’ve been all this time. A scrap-book of sorts, a place to vent, organize some clinical tools and post a few good songs I’ve heard along the way.
