Mosquito-borne disease in Bosnia and Herzegovina — 2025–2026 data
As of 17 June 2026, Mosticare tracks Bosnia and Herzegovina surveillance for West Nile virus and Aedes albopictus (vector establishment). No autochthonous human cases are reported year-to-date in 2026. Each figure cites the responsible national or EU authority.

About surveillance in Bosnia and Herzegovina
Bosnia and Herzegovina is an EU-neighbouring country outside ECDC's EU/EEA confirmed reporting set, so its mosquito-borne-disease data is sparse. West Nile virus circulates here: the most recent reliably-published national human count is 13 cases in 2014 (ECDC), and WNV lineage-2 RNA was first detected in local Culex pipiens mosquitoes in 2025 (One Health). No autochthonous human WNV case was reported for BiH in the 2025 European season per ECDC/EFSA. The Asian tiger mosquito (Aedes albopictus) is present.
Frequently asked questions
What mosquito-borne diseases is Bosnia and Herzegovina monitoring in 2026?
Mosticare tracks Bosnia and Herzegovina surveillance for West Nile virus and Aedes albopictus (vector establishment), each sourced to the responsible national authority or ECDC.
How many West Nile virus cases were reported in Bosnia and Herzegovina in 2025?
No autochthonous human West Nile virus case was reported for Bosnia and Herzegovina in 2025. As of 3 December 2025, ECDC and EFSA listed 14 European countries with locally acquired human cases (Albania, Bulgaria, Croatia, France, Germany, Greece, Hungary, Italy, Kosovo, North Macedonia, Romania, Serbia, Spain and Türkiye) — BiH was not among them. The virus is nonetheless circulating: 2025 was the first year WNV lineage-2 RNA was detected in mosquitoes in the country (One Health journal).
Has Bosnia and Herzegovina ever recorded West Nile virus in people?
Yes. The most recent reliably-published national human case count is 13 cases in 2014, when ECDC noted BiH was the first country in the region to report cases that season. Two probable neuroinvasive cases were also described in 2013 (Medicinski glasnik, 2015). BiH reports sparsely as an EU-neighbouring country, so no comprehensive annual human series is published.
Is the Asian tiger mosquito (Aedes albopictus) present in Bosnia and Herzegovina?
Yes. ECDC's distribution data lists Bosnia & Herzegovina among countries where Aedes albopictus is present, and a 2025 field survey reported it at nine locations across the north, north-east, east and centre of the country. This species can transmit dengue and chikungunya where it becomes established, although no locally acquired dengue or chikungunya cases have been reported in BiH.
Which mosquito spreads West Nile virus in Bosnia and Herzegovina?
The common house mosquito, Culex pipiens, is the principal West Nile virus vector and the most abundant mosquito recorded in BiH (about 36% of females collected in a 2025 national survey). WNV lineage-2 RNA was detected in Culex pipiens pools from Bratunac and Orašje in 2025.

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.
