The National Institute of Allergy and Infectious Diseases (NIAID) awarded a $825,988 Project Grant under CFDA 93.855 Allergy and Infectious Diseases Research to Yale University. The grant aims to leverage spatial data science and social determinants data to reduce HIV incidence in high-prevalence counties across the U.S. as part of the Ending the HIV Epidemic (EHE) initiative. The project involves developing transportation-based measures of PrEP accessibility, quantifying how community mental health, social capital, and religious institution environments are associated with HIV diagnoses and PrEP uptake, and creating an interactive web-based data visualization tool to identify HIV hotspots and guide optimal PrEP provider allocations. Yale is partnering with the University of Texas Southwestern Medical Center as a sub-awardee, with Dr. Hui Luan serving as a co-principal investigator responsible for the statistical and geospatial analyses and web tool development. The award began on Aug 26, 2024 and is slated for completion on Jun 30, 2028.
