The Asian tiger mosquito, known for transmitting diseases such as dengue fever and West Nile virus, is expanding its range across Europe, including northern latitudes. This has prompted increased vigilance from public health officials.
Asian Tiger Mosquito
The Asian tiger mosquito (aedes Albopictus) is a small mosquito, seldom exceeding 0.9 cm. It is identifiable by its black and white coloring, with distinctive patterns on its abdomen and hind legs, and a white line extending from its back. Originally from the Asian-Pacific region, it has spread globally through international trade and travel.

María Velasco,a spokeswoman for the Spanish Society for Infectious Diseases and Clinical Microbiology (SEIMC),told ConSalud.es that disease vectors are expanding their geographical distribution and multiplying in areas where they previously did not exist.
West Nile Virus Cases Surge in Spain; Experts Anticipate Further Increases
The tiger mosquito is a vector for diseases including dengue fever, zika, chikungunya, and West Nile virus. World Health Association (WHO) data indicates dengue fever is among the deadliest vector-borne diseases globally, causing nearly 100 million symptomatic cases and an estimated 40,000 deaths annually. While cases of dengue and othre tropical diseases remain relatively uncommon in Europe, they are increasing alongside the spread of invasive mosquito species.
Spain reported 158 cases of West Nile fever in 2024, according to the Ministry of Health, with 142 confirmed and 16 probable. The majority (118) were linked to infections in Andalusia, a popular tourist destination. Twenty deaths were attributed to West Nile fever.Italy also saw an increase in dengue cases in 2024.
Due to high humidity resulting from heavy spring rains, an increase in cases can be expected this year if we do not take strict preventive measures.
The Canary Islands are also facing increasing challenges with invasive mosquito species and tropical diseases, according to teneriffa-news.com. Authorities received 18 warnings regarding the tiger mosquito, especially affecting cruise terminals in Santa cruz de Tenerife and Las Palmas de Gran Canaria, and also some greenhouses in Tenerife.
Public Cooperation Key to Mosquito Control
Spanish authorities emphasize the importance of public involvement in controlling invasive mosquito species. Approximately one-fifth of all reports originate from concerned citizens. Consalud.es reports that 60% to 80% of breeding grounds are located on private property. The Anecpla recommends the following preventative measures:
- Regularly empty saucers under flower pots.
- Maintain clear drains and gutters.
- Remove or cover any containers that can accumulate water.
- Regularly change and cover water in children’s pools.
The Canary Islands have maintained an active surveillance system as 2013 to monitor the spread of invasive mosquitoes. A free app is available throughout Spain for reporting sightings of tiger mosquitoes and other species. This application is also used in other countries, including Austria. while current dry conditions in Germany are not ideal for mosquitoes, vigilance remains crucial throughout the summer. Effective mosquito protection measures are available.
