I know that, but if available, I'd like to know the percentages as a matter of education. If the CDC doesn't track it, they probably should. All of the writings I have read suggest that HIV is transmitted "better" when another STD is present, but that information never seems to be backed up by any hard data. I sometimes wonder who comes up with all this stuff on the internet and puts it out there with no CDC data to support it.
I don't take just anyone's word for it when I am getting educated...I want to know it is fact, and hopefully government stats can be the best facts we can get.
I can tell you that you don't have to have another STD to contract HIV.
