Who could benefit from this research
✓Could help
People living with HIV, especially in regions prone to droughts, floods, and storms, who are linked to care and have data available in the IeDEA collaboration.
✕Less likely to help
Individuals not receiving HIV care or not exposed to EWEs in their communities may see limited direct benefit.
What this research studies
Extreme weather events are becoming more common and may disrupt HIV care. The study will use data from a large international cohort and analyze how weather shocks affect ART initiation, adherence, and retention in care. Researchers plan to combine long-term cohort information with context from affected regions to identify pathways by which EWEs impact health outcomes. The work aims to point to practical interventions to protect HIV care during climate-related events.
Why it matters
Potential benefit: If successful, findings could guide policies and programs to keep people on HIV treatment during extreme weather.
How similar studies have gone: Preliminary analyses suggest weather-related disruptions can delay ART and increase loss to follow-up, but rigorous longitudinal evidence is needed.
