Frequently asked questions
What mosquito-borne diseases is Malta monitoring in 2026?
Mosticare tracks Malta surveillance for West Nile virus, each sourced to the responsible national authority or ECDC.
Were there any West Nile virus cases in Malta in 2025?
No. According to ECDC surveillance, Malta reported zero autochthonous (locally acquired) human West Nile virus cases in the 2025 season. Malta does not appear in the list of 14 European countries that reported human cases in 2025 (ECDC, as of 10 December 2025).
Which mosquitoes are present in Malta?
ECDC/VectorNet lists the invasive Asian tiger mosquito (Aedes albopictus) as established in Malta as of the June 2025 distribution map; on an island Malta's size this means it is effectively present nationwide. Aedes aegypti (the yellow fever mosquito) is not recorded as established in Malta. The common house mosquito Culex pipiens is the principal European vector of West Nile virus.
Who monitors mosquito-borne disease in Malta?
The Infectious Disease Prevention and Control Unit (IDCU), within the Health Promotion and Disease Prevention Directorate (HPDP) of Malta's Ministry for Health, is the national centre responsible for the surveillance, prevention and control of infectious diseases in the Maltese islands. EU-level surveillance is coordinated by ECDC and the VectorNet network (ECDC/EFSA).
Was there any local dengue or chikungunya in Malta in 2025?
No autochthonous dengue, chikungunya, Zika or Usutu virus transmission was reported in Malta in 2025. ECDC reported EU/EEA local dengue and chikungunya transmission that year only in France, Italy, Spain and Portugal (Madeira).

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.
