Who could benefit from this research
✓Could help
People living with HIV/AIDS in regions frequently affected by extreme weather, including sub-Saharan Africa and other vulnerable areas, who may experience care disruptions.
✕Less likely to help
Patients in regions with minimal exposure to extreme weather or those not engaged in HIV care may see limited relevance.
What this research studies
Researchers will use data from the global IeDEA cohort and other sources to examine how extreme weather changes access to HIV care, ART initiation, follow-up, and infection rates. The study combines longitudinal analyses with qualitative insights to identify causal pathways linking weather, food security, and ART adherence. The goal is to find actionable strategies to keep people on treatment during and after extreme weather events. This work centers on real patients in settings most affected by climate-related disruptions, aiming to inform programs and policies.
Why it matters
Potential benefit: If successful, the work could inform interventions to maintain ART access and reduce loss to follow-up during extreme weather events.
How similar studies have gone: Preliminary analyses suggest weather-related disruptions can delay ART initiation and increase follow-up losses, but rigorous longitudinal evidence is needed.
