You know how chief complaints present to the ED in multiples?

I haven't had to manage such cases in a long time and so needed to look up the recent guidelines from the CDC.
The trick is not to forget about all the co-existing problems and infections beyond just HIV. Specifically, don't forget about gonorrhea, chlamydia, and trichomonas. The 2010 CDC website on STD treatment and sexual assault is here:
