Domain: Infectious Disease Epidemiology
Determinants of infectious disease burden including vaccination coverage, healthcare capacity, and cross-border transmission dynamics
Temporal scope: 2000-present | Population: Countries worldwide
Key Findings
- Each 10 percentage point increase in DTP3 vaccination coverage is associated with a 5-7% reduction in under-5 mortality from vaccine-preventable diseases (negative, strong)
- Healthcare workforce density is negatively associated with infectious disease mortality across 204 countries after controlling for income and urbanization (negative, strong)
- Countries scoring above 60 on IHR core capacity index experienced significantly shorter epidemic durations compared to countries scoring below 40 (negative, moderate)
- Antibiotic resistance prevalence is positively associated with treatment failure rates and excess mortality from bacterial infections, with an estimated 700,000 annual deaths attributable to AMR globally (positive, strong)
- Vaccination coverage rate is the single strongest modifiable predictor of communicable disease burden in low-income countries (negative, strong)
