A new Grand Challenges grant opportunity, with applications due no later than June 16, 2026, at 11:30 AM Pacific Daylight Time:
Estimating the Global Burden of Diarrheal Diseases: Reliable burden estimates are essential for guiding investments in prevention, treatment, and product development. However, estimating diarrheal mortality, morbidity, and pathogen-specific burden remains challenging for a number of reasons. Through this RFP (Request for Proposals), the Gates Foundation seeks to support independent estimation efforts that inform the overall burden of diarrhea and pathogen-specific contributions, clarify key sources of uncertainty, and produce decision-useful estimates for policymakers, researchers, and global health partners.
Please refer to the RFP (opens PDF) for full details on scope and eligibility. We will also host a dedicated webinar on May 14, 2026, from 8:00–9:00 a.m. PT, featuring an overview of the opportunity and time for Q&A.
Please register to attend, and submit your questions ahead of the session. A recording will be posted on the challenge page following the session for those unable to join live.
