Sexual mixing, drug exchanges, and infection risk among long-haul truck drivers

Despite extensive anecdotal evidence on US long-haul truckers' risk interactions on the road, links between their sexual mixing and drug exchanges and their potential risk for STI/BBI acquisition and dissemination remain insufficiently documented. Grounded in social ecological theories and multi method ethnographic data, this paper examines the sexual transactions and drug exchanges of key members of US trucker risk networks within diverse trucking milieux. Research has uncovered four key trucker-centered populations and their diverse risk exchanges: (a) straight male truckers who engage in casual sex with women; (b) female sexworkers (known as "lot lizards") who solicit truckers; (c) intermediaries who broker sex and drug exchanges between truckers, drug dealers and sexworkers; and (d) male truckchasers who cruise for truckers in physical and virtual milieux to engage in sex. Concurrent sexual partnerships of truckers have the potential to amplify initial infections by linking individuals of disparate epidemiological settings, thereby enabling pathogens to travel rapidly and efficiently to disparate regions. The comprehensive delineation of the role of long-haul trucking in potential disease spread is required for the development of effective STI/HIV prevention programs for populations of interest.
