While the tiger mosquito continues its expansion in Romandy, Ticino has seen a decrease in its population density. This is the result of long-term efforts that now serve as a reference for the rest of the country.
The arrival of the warm season marks the resumption of efforts to combat the tiger mosquito in Romandy. While the measures implemented in recent years have helped slow the spread of this insect, prevention remains crucial, according to the authorities of Vaud and Valais on Wednesday. The tiger mosquito bites during the day, in an aggressive and repeated manner, and is a vector of diseases such as dengue, Zika, and chikungunya.
