Consider the potential impact of circuit party weekends on HIV infection rates and rates of infection with other sexually transmitted diseases, based on sexual mixing opportunities and patterns both within and beyond the 3-day periods. Our data pertain to a single circuit party weekend for each participant. If we multiply the prevalence of sexual risk behavior by the median of 3 parties per year revealed in this sample, and if we consider the large number of men who attend circuit parties, as well as the growing popularity of such parties, then the likelihood of transmission of HIV and other sexually transmitted diseases among party attendees and secondary partners becomes a real public health concern.<ref> | Consider the potential impact of circuit party weekends on HIV infection rates and rates of infection with other sexually transmitted diseases, based on sexual mixing opportunities and patterns both within and beyond the 3-day periods.
