Deadline: 16-Jun-2026
The Bill & Melinda Gates Foundation is funding projects to improve estimates of diarrheal disease burden in children under five in low- and middle-income countries (LMICs). The program supports modeling of mortality, morbidity, pathogen attribution, and DALYs for 2025 using robust epidemiological methods. Grants can reach up to USD 1.5 million for a duration of two years.
Funding Opportunity: Global Diarrheal Disease Burden Estimation (LMIC Focus)
Overview
This initiative strengthens estimates of diarrheal disease burden in LMICs through improved modeling of mortality, morbidity, and pathogen-specific impacts in children under five.
It supports organizations with expertise in epidemiology, biostatistics, and infectious disease modeling.
Objectives
- Estimate total diarrheal mortality in children under five
- Measure pathogen-specific mortality and morbidity
- Improve attribution methods for coinfections
- Generate uncertainty-aware burden estimates
- Strengthen LMIC analytic capacity
Key Outputs Required
Mortality
- Total diarrheal deaths (under age 5)
- Mortality incidence rates
- Pathogen-specific mortality fractions
Morbidity
- Total disease cases
- Severe cases
- Hospitalizations
Modeling Outputs
- DALYs
- Historical trends
- Regional/global aggregation
- Cost burden estimates
Priority Pathogens
- Rotavirus
- Shigella
- Adenovirus 40/41
- Norovirus GII
- ST-ETEC
- Cholera
- Cryptosporidium
- Campylobacter
Why This Matters
Diarrheal diseases remain a major cause of child mortality in LMICs. Reliable estimates are essential for:
- Vaccine development
- Health system planning
- Resource allocation
- Child survival programs
Current estimates vary due to:
- Limited surveillance data
- Diagnostic inconsistencies
- Modeling differences
- Incomplete pathogen data
Geographic Priorities
- India
- Nigeria
- Sub-Saharan Africa
- Other high-burden LMICs
