About this data
Mosticare aggregates and re-publishes vector-borne disease surveillance from ECDC, EFSA, and national ministries of health. Mosticare is an aggregator, not a primary surveillance authority — every figure on this page cites the originating source and is independently verifiable. This is a partial aggregation; for the complete EU/EEA totals, ECDC is the primary source.
