About Dengue
Dengue is transmitted by Aedes mosquitoes — Aedes aegypti and Aedes albopictus. In the Mosticare feed, dengue surveillance currently covers the Madeira archipelago (Portugal), where DENV-2 has been detected in Aedes aegypti vector populations. This page reflects only the territories Mosticare tracks; for the complete EU/EEA count of imported and autochthonous dengue cases, ECDC is the primary source.

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.
