## Abstract

PROJECT SUMMARY
Adolescent girls and young women (AGYW) in South Africa have one of the highest HIV-1 incidences globally
and are a key target population for oral pre-exposure prophylaxis (PrEP) to prevent HIV-1 acquisition. In addition,
AGYW seeking PrEP frequently experience high rates of curable sexually transmitted infections (STIs). Current
South African PrEP guidelines recommend syndromic management for STIs, meaning that only women reporting
symptoms will receive treatment. It is well-established that syndromic management is particularly problematic
for women as the vast majority of curable STIs are asymptomatic. Persistent, untreated infections can lead to
serious reproductive health outcomes, including pelvic inflammatory disease, infertility, ectopic pregnancy,
neonatal infections, and increased risk HIV-1 acquisition. The high STI incidence in AGYW, which is on the rise,
emphasizes the need for effective screening strategies to reduce rates of STIs and their associated impact on
sexual and reproductive health outcomes. Among women who are at risk for HIV-1 and interested in initiating
PrEP, point-of-care diagnostic STI testing and expedited partner therapy (EPT) are two strategies that could
have a substantial impact on STI incidence. Few studies have evaluated the feasibility and acceptability of EPT
in low and middle-income countries and, to date, no studies have assessed the implementation of point-of-care
STI testing and EPT in the context of PrEP scale-up. This proposal builds on nearly a decade of collaborative
HIV/STI prevention research to conduct a prospective cohort study of AGYW eligible for PrEP in South Africa in
which we will assess the acceptability of point-of-care STI testing plus EPT and its impact on the incidence of
common curable STIs over 12 months of follow-up (Aims 1 and 2). We will undertake qualitative interviews with
participants and their male partners to identify facilitators and barriers to EPT uptake (Aim 2) and conduct a
comparative cost analysis to estimate the cost per person tested using point-of-care STI testing with and without
EPT incremental to the cost of standard of care (Aim 3). Findings from the proposed research will provide
essential knowledge for national policy makers to advance approaches to STI screening and treatment that will
lead to reductions in STIs and improvements in AGYW sexual reproductive health. The data generated from this
proposal are essential to inform efforts to reduce the burden of STIs and HIV-1 in women achieve the 2030
Sustainable Development Goals, which includes substantial reductions in HIV and STIs in key at-risk populations.
