Reporting bounds and case definitions vary; historical baselines are a separate comparison measure. Worldwide share compares this country's reported figure with the sum of all countries reporting measles to ENCLAI for that year. "Incomplete year" means our sources cover less than ten months of that year, so no full-year figure is shown; "outbreak total to date" is a running total since an outbreak began, not a count for one year.

About this data

Figures are reported case counts as published by the originating health authorities, compiled by ENCLAI from 444 verified surveillance sources. Nigeria figures reflect the reporting available to ENCLAI; reporting periods and case definitions differ between sources, and a missing report does not establish zero cases. ENCLAI holds measles records for Nigeria dated from 2019. How we verify and update data: methodology & Trust Center · understanding case counts.
