Who could benefit from this research
✓Could help
People living with HIV/AIDS across regions vulnerable to extreme weather, especially in sub-Saharan Africa and other high-risk areas.
✕Less likely to help
Individuals not engaged in HIV care or in regions with minimal EWE exposure may see limited direct benefits.
What this research studies
Researchers will use data from the global IeDEA cohort, along with country-specific information on extreme weather, to study how EWEs impact ART initiation, retention in care, adherence, and clinical outcomes over time. The study combines quantitative analysis of large datasets with contextual insights from affected communities to identify pathways linking weather events to HIV care. The goal is to inform strategies to keep people on treatment and improve care during and after extreme weather episodes.
Why it matters
Potential benefit: If successful, the project could lead to better support systems and policies that protect HIV care continuity during extreme weather events.
How similar studies have gone: Preliminary findings suggest weather-related disruptions can affect ART initiation and retention, but rigorous longitudinal data are needed to confirm pathways.
