| Country / region | Disease | Cases | Deaths | Period | Source | Updated |
|---|---|---|---|---|---|---|
| Ukraine · Kyiv city & Kyiv Oblast (most cases), with cases in Poltava and Cherkasy oblasts | West Nile virus | 88 | 11 | 2024 transmission season (since July 2024) | Public Health Center of the Ministry of Health of Ukraine; Deputy Minister of Health & Chief Sanitary Doctor Ihor Kuzin | 17 June 2026 |
About surveillance in Ukraine
West Nile virus is endemic in Ukraine. The national surveillance authority is the Public Health Center of the Ministry of Health of Ukraine. The most recent published national figure is the 2024 transmission season: 88 human cases and 11 deaths since the start of July 2024, attributed to Ukraine's Deputy Health Minister and Chief Sanitary Doctor. The native Culex pipiens mosquito is the principal vector; Ukraine sits outside the ECDC EU/EEA reporting set, and no 2025 national count has been published.
Frequently asked questions
What mosquito-borne diseases is Ukraine monitoring in 2026?
Mosticare tracks Ukraine surveillance for West Nile virus, each sourced to the responsible national authority or ECDC.
Does West Nile virus circulate in Ukraine?
Yes. West Nile virus is endemic across Ukraine, with documented natural foci and recurring human cases. The largest recent outbreak was in 2024, when Ukraine's Health Ministry reported 88 human cases and 11 deaths from the start of July 2024, concentrated around Kyiv. The native Culex pipiens (common house mosquito) is the principal vector.
Who reports West Nile virus data in Ukraine?
The Public Health Center of the Ministry of Health of Ukraine (Центр громадського здоров'я МОЗ України) is the national surveillance authority. Because Ukraine is not part of the EU/EEA, it is outside the ECDC weekly West Nile surveillance set — ECDC lists Ukraine only as a 'neighbouring country.' Mosticare is a civil-society aggregator that re-publishes these official figures and does not collect surveillance data itself.
Is there a 2025 West Nile virus case count for Ukraine?
No national figure has been published for 2025. Ukraine does not appear in ECDC's 2025 locally-acquired West Nile virus list, and the Public Health Center has not published a 2025 count. Surveillance has been disrupted by the war, so the most recent reliable figure remains the 2024 season.
Are Aedes 'tiger' mosquitoes a concern for disease in Ukraine?
Not currently. The invasive Aedes albopictus (Asian tiger mosquito) is not listed as established in Ukraine in ECDC/VectorNet distribution maps, and Aedes aegypti is not established in mainland Ukraine. The country's mosquito-borne disease burden is driven by West Nile virus carried by native Culex mosquitoes, not by Aedes-borne diseases such as dengue or chikungunya.

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.
