    Abstract

    AMETHIST is a study of Adapted Microplanning to Eliminate Transmissible HIV in Sex Transactions. In South Africa, the study examined how the AMETHIST model could be translated to a rural KwaZulu-Natal setting with less established clinical services for female sex workers. The work began with rapid participatory mapping to identify where, when and how sex work takes place, followed by a respondent-driven sampling bio-behavioural survey and clinical-service follow-up.

    Study Aim: To investigate translation of AMETHIST to rural KwaZulu-Natal, South Africa; to understand HIV risks and service needs among female sex workers; and to inform delivery, impact and cost-effectiveness of HIV prevention and related clinical services.

    Specific Objectives:

    • Describe the prevalence and patterns of sex work in the study setting, including how sex work is defined and organised.
    • Understand sexual risk across and along the sex-work life course, including transitions into and out of sex work.
    • Assess unmet health needs among female sex workers.
    • Determine how to deliver the AMETHIST intervention in rural KwaZulu-Natal, South Africa.
