The dumbest study in a long time?

I put this under "humor" because it's so completely ridiculous. In a long line of idiotic studies, this one is the best I've seen in a long, long time. Researchers have figured out, after studying 997 HIV-positive men in Africa, that if an adult male doesn't abstain from sex while healing from circumcision, he increases his sexual partner's risk of contracting the disease.

From AP: "Among 70 men with HIV who underwent circumcision, 11 of their female partners became infected with the virus in the month after the surgery. In contrast, only four partners of 54 uncircumcised men with HIV in the control group caught the virus — nearly half the rate, early results showed."

So, they followed HIV-positive men, didn't stop them from having sex, knew with whom they had sex with, and then just went and tested the women? Do these people really see Africa as a Petri dish? And are these researchers really that uneducated that they couldn't figure out that an open wound on a man's penis may increase the chances of giving his partner HIV? This ranks up there with the "obesity in the military" study I heard about a while back. Your dollars at work.
