The aim of this study is to evaluate an approach to reduce STIs among high-risk groups including men who have sex with men, female sex workers and mining populations in Dar es Salaam and Shinyanga regions of Tanzania.
Primary research questions:
1) Is there a reduction in prevalence of laboratory confirmed STIs (a combined measure of gonorrhea, chlamydia and Treponema pallidum) in men who have sex with men (MSM) in Dar es Salaam and female sex workers (FSW) in Shinyanga after six months of presumptive treatment of STIs (PPT) availability?
2) Is there a reduction in prevalence of symptomatic STIs in male mine workers in Shinyanga after six months of PPT availability for FSW?
Secondary research questions:
3) What associations are observed between demographics, socio-economic status, biological risk factors, and STI prevalence?
4) Are there changes in sexual risk taking behaviors while receiving PPT?
5) What is the prevalence of cervical cancer lesions, as assessed through Visual Inspection with Acetic Acid (VIA), in FSW?
