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 hepatitis a 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.
| Month | Records | Reporting sources |

| May 2026 | 54 | 1 |
| Aug 2026 | 8 | 1 |
| Sep 2026 | 4 | 1 |
| Oct 2026 | 6 | 1 |
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. 6 records were logged in the last 30 days.
