## TL;DR

This paper reviews 40 years of HIV research in French Guiana, highlighting how local research and public health efforts have improved responses to the epidemic in a unique social and geographic context.

## Contribution

The paper provides a comprehensive overview of how integrated research and public health actions have shaped HIV responses in French Guiana over four decades.

## Key findings

- Local research in French Guiana has continuously contributed to public health decisions and adapted HIV prevention and care.
- Prospective data collection and focused studies have generated valuable insights into vulnerable populations and the local HIV epidemic.
- The integration of research and public health was crucial for addressing the unique challenges of the region.

## Abstract

The drivers of the HIV epidemic, the viruses, the opportunistic infections, the attitudes and the resources allocated to the fight against HIV/AIDS, vary substantially across countries. French Guiana, at the crossroads between Amazonian South America and the Caribbean, constitutes a singular context with poor populations and rich country health funding, which has allowed researchers to gather lots of information on the particulars of our epidemic. We aimed to focus on the little known story of forty years of HIV research in French Guiana and emphasize how local research intertwined with public health action has yielded continuous progress, despite the difficult social conditions of the affected population. We searched Web of Science and associated local experts who worked through much of the epidemic in selecting the most meaningful products of local research for clinical and public health outcomes in French Guiana. Research tools and facilities included, from 1991 onwards, the HIV hospital cohort and the HIV-histoplasmosis cohort. Ad hoc studies funded by the ANRS or the European Regional Development fund shed light on vulnerable groups. The cumulative impact of prospective routine collection and focused efforts has yielded a breadth of knowledge, allowing for informed decisions and the adaptation of prevention, testing and care in French Guiana. After this overview, we emphasize that the close integration of research and public health was crucial in adapting interventions to the singular context of French Guiana.
