The syndemic of AIDS and STDS among MSM.

The spread of HIV and other STDs among men who have sex with men (MSM) has been labeled a syndemic because in this population a number of different and interrelated health problems have come together and interact with one another. The various elements of the syndemic have an additive effect, each one intensifying the others. These factors include the number of infectious diseases endemic in this population, the high rate of substance abuse problems and psychological disorders, and the significant percentage of MSM who have experienced childhood sexual abuse and other adverse events. While MSM are disproportionately affected by HIV, syphilis, and other STDs, health activists from the gay community have systematically resisted the application of the full range of public health strategies traditionally used to prevent their spread. In the more than three decades since the beginning of the HIV/AIDS epidemic, there have been substantial advances in testing and treatment, yet the infection rate among MSM, and particularly young MSM, remains high, even as it has been dropping among other risk groups. This paper deals with the history of the syndemic, the failure of various risk reduction strategies, and treatment as prevention.
