Tiger mosquito reaches 40 municipalities in Portugal

The tiger mosquito (Aedes albopictus) has been identified in 40 municipalities across Portugal, leading health authorities to issue a "Level 1" yellow alert. While the insect can transmit viruses like dengue and Zika, authorities confirmed there is no active local circulation of these pathogens and that all cases recorded in 2026 were imported from abroad. Residents are advised to eliminate standing water in containers, use repellent, and report sightings via platforms such as MosquitoWeb and Mosquito Alert.

Why it matters

If you live in one of the 40 affected municipalities, you should follow the health authority's guidance to remove standing water around your home to prevent the species from breeding and becoming a local health risk.
