Also the RAW score leaves out one very important factor. Transmissibility. The score they have given to HIV was 180. They are saying have unprotected sex with 180 people and you are sure to get HIV. This is insaneley low.

Isn't the figure insanely high then? 1/180 is higher than 1/1000.

Edit: granted, I realize they are estimates. And, I realize things such as your partners having other std's, when they sero converted, and viral loads all raise/lower your chances of getting their std's, I just think you may have faltered on your terminology.

Edit 2: I agree with your comment I'm regards to transmissibility. For instance, let's look at men who have sex with heterosexual women. Let us assume the man is HIV negative. In the first example, let's assume the woman has HIV. There for, according to your chart courtesy of the CDC, the man has a 1/2000 chance of getting HIV in that scenario.

Now, let's assume that the woman's status is unknown. 1/1000 women have HIV (1/1000 is for the general populace. Risk will skyrocket for drug users or amongst the African american community or street walkers). Now, couple that with the 1/2000 chance a man will contact HIV if he has sex with a known positive woman, and you are in the vicinity of 1/2,000,000 chance of getting the disease. Granted, once again, if she has another STD, your risk can effectively double. If she is recently unknowingly infected, your risk can further increase.

Either way, always always wear a condom.

The only reason I comment is because I did fail to wear a condom one time. Luckily I tested negative for everything. But, the doctors and workers at the clinic told me by and large that I would probably be okay. And, I was.

I wish I always wore a condom. The stress and "trauma" wasn't worth it. And, I still "suffer" from that anxiety today. But, we need to a knowledge that if you make a mistake, there is often a light at the end of the tunnel.
