About surveillance in Armenia
West Nile virus is the principal mosquito-borne disease on record in Armenia. The country reported its first-ever WNV outbreak in 2024, with 108 laboratory-confirmed human cases and 2 deaths (National Center for Disease Control and Prevention, under the Ministry of Health). A smaller 2025 season followed with 2 confirmed cases. Armenia sits outside ECDC's EU/EEA reporting set, so figures come from the national authority. The invasive mosquito Aedes albopictus is established; Culex pipiens is the main WNV vector.
Frequently asked questions
What mosquito-borne diseases is Armenia monitoring in 2026?
Mosticare tracks Armenia surveillance for West Nile virus, each sourced to the responsible national authority or ECDC.
Has West Nile virus been recorded in Armenia?
Yes. Armenia recorded its first documented WNV outbreak in 2024, with 108 laboratory-confirmed human cases and 2 deaths reported by early September 2024, according to the National Center for Disease Control and Prevention under the Ministry of Health. The first human case that season was diagnosed on 7 August 2024, and the virus had been detected in mosquitoes in Aragatsotn province in late July 2024.
How many West Nile fever cases did Armenia report in 2025?
As of 25 August 2025, the National Center for Disease Control and Prevention reported 2 laboratory-confirmed West Nile fever cases for the 2025 season, with no deaths reported, and described the epidemiological situation as stable. This is far smaller than the 2024 outbreak.
Which mosquitoes spread West Nile virus in Armenia?
The principal vector is Culex pipiens, the common house mosquito, which is widely distributed across Armenia. The invasive Asian tiger mosquito (Aedes albopictus) is also established in Armenia, first reported near the Georgia border in 2016, but it is not the main driver of West Nile virus transmission.
Is Mosticare the source of these Armenia figures?
No. Mosticare is a civil-society aggregator that re-publishes figures from named public-health authorities. The Armenian case and death counts here are attributed to the National Center for Disease Control and Prevention under Armenia's Ministry of Health, and the vector data to a peer-reviewed survey in the journal Parasite. Mosticare does not collect surveillance data, run mosquito traps, or operate a sentinel network.

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.
