The social determinants and epidemiology of sexually transmitteddisease (STD) were studied in rural communities in Mwanza Region,Tanzania, in the context of the phase specific model of STDtransmission. The prevalence of HIV and syphilis was higherin communities close to main roads, and lower in communitiesliving on islands in Lake Victoria, probably reflecting theproportion of high risk individuals in the population. The prevalenceof Herpes simplex virus type 2 infection, gonorrhoea, chlamydialinfection, and trichomoniasis was similar in all types of community,reflecting the fact that these infections remain in the hyperendemicphase. The transmission of STDs is fuelled by high populationmobility and by the presence of high risk individuals in ruralas well as roadside communities.
