Our review highlights heterogeneity in cost effectiveness by pandemic severity, intervention type, bundling of measures, and timing. Strategies that combined low-cost NPIs like masks or hand hygiene demonstrated better value, while socially disruptive measures like school and business closure incurred high costs with inconsistent cost-effectiveness outcomes. Integration with vaccines or antivirals further enhanced cost effectiveness. Evidence gaps include the scarcity of evaluations from low-resource settings and variability in country-specific value thresholds. Addressing these gaps is essential for guiding efficient and cost-effective pandemic preparedness.
