| Estonia | 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 Estonia
Estonia's communicable-disease surveillance is run by the Health Board (Terviseamet). For the 2025 season, the European Centre for Disease Prevention and Control (ECDC) did not list Estonia among the 14 European countries reporting locally acquired human West Nile virus cases, so Estonia's 2025 autochthonous human count is zero. ECDC VectorNet does not record the invasive mosquitoes Aedes albopictus or Aedes aegypti as established in Estonia; the relevant local vector is the Culex pipiens complex.
Frequently asked questions
What mosquito-borne diseases is Estonia monitoring in 2026?
Mosticare tracks Estonia surveillance for West Nile virus, each sourced to the responsible national authority or ECDC.
Were there any West Nile virus cases in Estonia in 2025?
No locally acquired (autochthonous) human cases. ECDC's end-of-season surveillance for 2025 listed 14 European countries with human West Nile virus cases, and Estonia was not among them. Separately, Estonian veterinary authorities reported the country's first-ever West Nile virus detection in February 2025 — in a dead bird (a Northern Goshawk), which is an animal finding rather than a human case.
Is the Asian tiger mosquito (Aedes albopictus) established in Estonia?
No. ECDC's VectorNet distribution map (June 2025) does not list Estonia among the EU/EEA countries where Aedes albopictus is established. The invasive Aedes mosquitoes are not established across the Baltic and Nordic region. The mosquito species relevant to West Nile virus locally is the native Culex pipiens complex.
Were there any dengue or chikungunya cases caught locally in Estonia in 2025?
No. ECDC recorded locally acquired chikungunya in France and Italy in 2025, and locally acquired dengue in France, Italy and Portugal (Madeira). No autochthonous dengue or chikungunya was reported in Estonia, consistent with the absence of established Aedes albopictus or Aedes aegypti there.
Who is the official surveillance authority for Estonia?
The Health Board (Terviseamet) is the competent authority for communicable-disease control in Estonia. The pan-European figures cited here are owned by the European Centre for Disease Prevention and Control (ECDC). Mosticare is an independent civil-society aggregator and re-publishes these authorities' data; it does not collect surveillance data itself.

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.
