About surveillance in Latvia
In Latvia, the national authority for infectious-disease surveillance is the Centre for Disease Prevention and Control (Slimibu profilakses un kontroles centrs, SPKC). For the 2025 season, ECDC reported no autochthonous human West Nile virus cases in Latvia, which was not among the 14 European countries that recorded locally acquired cases. ECDC VectorNet maps (June 2025) record neither Aedes albopictus nor Aedes aegypti as established in Latvia.
Frequently asked questions
What mosquito-borne diseases is Latvia monitoring in 2026?
Mosticare tracks Latvia surveillance for West Nile virus, each sourced to the responsible national authority or ECDC.
Were there any West Nile virus cases in Latvia in 2025?
No. According to the European Centre for Disease Prevention and Control (ECDC), Latvia reported no autochthonous (locally acquired) human West Nile virus cases during the 2025 transmission season. Latvia is not among the 14 European countries that recorded locally acquired human cases that year.
Is the Asian tiger mosquito (Aedes albopictus) present in Latvia?
Not as an established population. ECDC's VectorNet distribution map for June 2025 lists 16 EU/EEA countries where Aedes albopictus is established; Latvia and the other Baltic states are not among them. Aedes aegypti is likewise absent, being established within the EU/EEA only in Cyprus.
Which mosquito carries West Nile virus in the Baltic region?
The principal vector at this latitude is the common house mosquito, Culex pipiens, which transmits West Nile virus between birds and occasionally to humans. It is native and widespread across northern Europe, although no human West Nile virus transmission was recorded in Latvia in 2025.
Who monitors mosquito-borne diseases in Latvia?
The Centre for Disease Prevention and Control of Latvia (Slimibu profilakses un kontroles centrs, SPKC), under the Ministry of Health, is the national authority responsible for epidemiological surveillance of infectious diseases. It tracks affected areas using the weekly maps published by the ECDC.

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.
