Mozzwise Briefing

Spain has seasonal mosquito activity from April through November, with peak populations during the summer months. The Mediterranean coast, the Ebro Delta, the Guadalquivir marshes, and the Balearic and Canary Islands have the highest mosquito density. Aedes albopictus has been established in the eastern Mediterranean coast since the early 2000s.

West Nile virus is the primary mosquito-borne disease concern, with seasonal circulation in the south. Dengue fever has seen rare locally-acquired cases. Chikungunya risk exists due to the established Aedes albopictus population. Overall risk remains low.

Culex pipiens is the dominant species in wetland and agricultural areas. Aedes albopictus is well established along the eastern coast and is an aggressive day-biting species. The warm Mediterranean climate and irrigation infrastructure support seasonal populations.
