Today is World AIDS Day. Here are some alarming statistics:

• Blacks bear the brunt of the AIDS epidemic in America. The number of new HIV infections in Blacks was 1.6 times the number in whites
• Blacks carry the bulk of the epidemic among women. While men accounted for two-thirds of new infections among Blacks, the infection rate among Black women is 15 times higher than among their white counterparts. High-risk heterosexual contact accounted for 80% of new infections among Black women.
• Black gay and bisexual men under 30 are hardest hit. Black "men who have sex with men" between the ages of 13 and 29 had infection rates roughly twice that of their white and Latino counterparts. This group had the highest number of infections of any other subset of gay and bisexual men.

Is there any explanation for these disproportionate figures? Are Blacks more promiscuous? Are Blacks more genetically inclined to receiving HIV? Are Blacks less educated about AIDS?

What do you say?
