Serosorting guides partner selection and may also inform choices about condom use. As public health and media attention increasingly focus on serosorting as a form of risk reduction for both HIV positive and HIV negative individuals, it has become increasingly important to understand this phenomenon. Lately, serosorting has been thrust into the mainstream media because it is thought to be partly responsible for the recent decrease in new HIV infections in San Francisco. As part of its newfound celebrity, serosorting is being considered as one of the possible next steps in behavioral HIV prevention for both negative and positive individuals. Yet while some endorse the strategy as a safer way to have sex without condoms, the impact of serosorting on the lives and health of HIV positive individuals has yet to be fully explored.
