Male mosquitoes carrying a parasite have been released in Barcelona, a first for Europe. The goal is to reduce the number of mosquitoes that can transmit diseases like dengue.
The release is part of a strategy that uses the parasite to affect the mosquito population. Introducing infected males is intended to lower the presence of disease-carrying insects in the area.
This is the first time such a release has taken place in Europe. The approach could become a new tool for controlling mosquito-borne infections in the region.
