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 e. coli infection 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.
