A systematic literature review of U.S. measles outbreak costs (2000–2025) across all 50 states, drawing on 19 articles and 8 gray-literature reports to estimate how costs scale with outbreak size from the medical provider and public health perspectives.
Average cost per measles case was **$43,203.65** (range: $33,415.75 from provider perspective to $58,591.50 including public health response). Fixed costs of initiating any outbreak response were ~**$297,747** (95% CI: $4,538–$590,956), with an incremental cost of **$16,300** per additional case. Cost elasticity relative to outbreak size was **0.86** (95% CI: 0.65–1.07), meaning costs grow slightly less than proportionally with outbreak size.
- Only 19 articles yielded usable data, with wide confidence intervals on fixed-cost estimates, suggesting high heterogeneity across studies. - Outbreak sizes varied enormously (1–802 cases), making cost comparisons across settings difficult. - Gray literature and CDC/state reports were included, introducing potential reporting inconsistencies.
Even a single measles case triggers roughly **$298,000** in fixed public health response costs before any per-case expenses — underscoring that vaccination and outbreak preparedness are far cheaper than containment. Clinicians and health systems should use the **$16,300 per-case incremental cost** figure when modeling budget impact of any uncontrolled outbreak.
