| Iceland | West Nile virus | 0 | 0 | 2025 transmission season | European Centre for Disease Prevention and Control (ECDC) — 2025 end-of-season West Nile virus surveillance (data to 3 December 2025) | 17 June 2026 |
About surveillance in Iceland
Iceland reported zero locally acquired human West Nile virus cases in the 2025 season: it is absent from the European Centre for Disease Prevention and Control's list of 14 countries reporting human WNV infection (ECDC, as of 3 December 2025). The invasive Aedes albopictus and Aedes aegypti mosquitoes are not established in Iceland (ECDC/VectorNet, June 2025). National surveillance sits with the Directorate of Health's Chief Epidemiologist.
Frequently asked questions
What mosquito-borne diseases is Iceland monitoring in 2026?
Mosticare tracks Iceland surveillance for West Nile virus, each sourced to the responsible national authority or ECDC.
Were there any West Nile virus cases in Iceland in 2025?
No. According to the ECDC, Iceland reported zero locally acquired (autochthonous) human West Nile virus cases in the 2025 transmission season. Iceland is not among the 14 European countries that reported human WNV infection as of 3 December 2025.
Does Iceland have the tiger mosquito (Aedes albopictus)?
No. Aedes albopictus is not established in Iceland. ECDC/VectorNet's June 2025 distribution map lists 16 EU/EEA countries with established populations, all of them in central and southern Europe; Iceland and the wider Nordic region are absent.
Does Iceland have mosquitoes at all?
Until very recently, no — Iceland was famously one of only two places on Earth (alongside Antarctica) without mosquitoes. In October 2025 the first mosquitoes ever recorded in Iceland — three Culiseta annulata specimens — were identified in Kjós, north of Reykjavík, by the Natural Science Institute of Iceland. This was a first detection rather than an established breeding population, and Culiseta annulata is a cold-tolerant nuisance species, not a recognised West Nile or dengue vector.
Who runs disease surveillance in Iceland?
Iceland's communicable disease surveillance is run by the Directorate of Health (Embætti landlæknis), where the Chief Epidemiologist is responsible for communicable disease control under the Minister's authority. For the European mosquito-borne-disease totals cited here, the source authority is the European Centre for Disease Prevention and Control (ECDC).

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.
The data behind this page is published as free, machine-readable feeds under CC BY 4.0 — the point-in-time incidence snapshot at /threat-map/feed.json (JSON Schema) and the multi-year trends at /threat-map/feed/trends.json (JSON Schema). See the live Europe threat map and the full data room.
