📊 Data Methodology Note

All country-level case numbers displayed on this tracker are derived from the sources listed above. Where exact annual breakdowns were unavailable, estimates were calculated from published incidence rates (e.g., China: 0.31/100K × population), regional aggregate totals (e.g., ECDC EU/EEA totals distributed by known country proportions), and published case fatality rates for each virus strain.

The 2026 data column shows 0 for all countries because country-level surveillance data for 2026 has not yet been published. The only verified 2026 event is the MV Hondius cruise ship cluster (8 cases, 3 deaths — WHO DON 2026-DON600), which is a multi-country event and is covered in the live WHO Disease Outbreak News feed on our News page.

Source reference numbers [1]–[7] are used throughout the dataset (data.js) and correspond to the numbered sources above.
