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 dengue fever 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.

A record is one dated surveillance publication or one row of an official table; a month with many records is a month with detailed reporting, not necessarily more cases. 7 records were logged in the last 30 days.
