WHO Silent Pandemic: Resistant Waterborne Pathogens on Track to Kill 10 Million/Year by 2050
Objective
Review the global AMR burden in waterborne transmission pathways and project future mortality under current investment trajectories.
Methodology
Review and synthesis of WHO Global Action Plan on AMR progress reports, IHME Global Burden of Disease AMR study, and Lancet Infectious Diseases AMR projections. Scenario modeling using IHME methodology.
Findings
Synthesis of WHO, IHME, and Lancet AMR Commission projections finds current waterborne AMR transmission pathways account for approximately 700,000 deaths/year. Under current investment trajectories, degrading water infrastructure combined with antibiotic use patterns are projected to drive this to 10M deaths/year by 2050 — surpassing cancer as a global mortality cause.
Interventions combining improved water quality, sanitation, and antibiotic stewardship can reduce projected 2050 burden by 73%. 5B/year above current trajectories.
Limitations
- •50-year projections have wide uncertainty intervals
- •AMR attribution methodology is contested in literature
- •Intervention efficacy projections based on modeled rather than observed data
