| Russia · Southern, North Caucasian & Volga Federal Districts | West Nile virussurveillance · 38 federal subjects with registered WNV cases (2024) | 0 | — | 2024 season (incidence 0.30 / 100,000; surveillance metric, not a case count) | Rospotrebnadzor (Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing) — surveillance review, Putintseva et al., 2025 | 17 June 2026 |
About surveillance in Russia
West Nile fever is endemic in southern Russia, with long-standing foci in the Volgograd, Astrakhan and Rostov regions. The national authority, Rospotrebnadzor, monitors it; an affiliated 2025 surveillance review reported a 2024 incidence of 0.30 cases per 100,000 across 38 regions. The main vector is the Culex pipiens mosquito. Russia is the only WHO European Region country with established Aedes albopictus and Aedes aegypti, both on the Black Sea coast.
Frequently asked questions
What mosquito-borne diseases is Russia monitoring in 2026?
Mosticare tracks Russia surveillance for West Nile virus, each sourced to the responsible national authority or ECDC.
Is West Nile virus present in Russia?
Yes. West Nile fever is endemic in southern Russia, with long-recognised foci in the Volgograd, Astrakhan and Rostov regions and wider circulation across the Southern, North Caucasian and Volga Federal Districts. According to a Rospotrebnadzor-affiliated surveillance review, 2024 saw an incidence of 0.30 cases per 100,000 population (about 2.6 times the long-term average), with cases recorded across 38 regions, the most on record.
How many West Nile cases did Russia report in 2024?
The most recent peer-reviewed surveillance review (Putintseva et al., 2025, in the Rospotrebnadzor-affiliated journal Problems of Particularly Dangerous Infections) publishes an incidence rate of 0.30 cases per 100,000 population and a case-fatality rate of 5.7% for 2024, rather than a single absolute national case count. Because no verified absolute figure was published, we do not state one. Russia is not part of the EU/EEA, so it is not included in the ECDC weekly West Nile virus reports.
Which mosquito spreads West Nile virus in Russia?
The main vector in southern Russia is the common house mosquito, Culex pipiens, which dominated collections during the major Volgograd outbreaks; Culex modestus acts mainly as an enzootic (bird-to-bird) vector but can bridge to humans where habitats overlap.
Are there tiger mosquitoes (Aedes) in Russia?
Yes, on the Black Sea coast. Aedes albopictus (the Asian tiger mosquito) has been established around Sochi since 2011 and spread inland between 2017 and 2019, and Aedes aegypti is also established in the Greater Sochi area. Russia is the only country in the WHO European Region with documented established populations of both species.
Has Russia had locally transmitted dengue or chikungunya?
No autochthonous (locally acquired) dengue, chikungunya, Zika or Usutu cases have been reported. Russia recorded its first-ever imported chikungunya case in Moscow on 29 August 2025, in a traveller returning from Sri Lanka; Rospotrebnadzor said mosquito populations in the country do not currently present an epidemiological threat of local spread.

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.
