Abstract:
The tiger mosquito (Aedes albopictus) is an invasive exotic species that has gradually colonized Europe, first detected in Switzerland in 2003. Beyond being a nuisance and an indirect threat to biodiversity, it is a public health concern. It can transmit arboviral diseases (for example, dengue, chikungunya, and zika). Colonized regions in Switzerland apply surveillance and control measures against the tiger mosquito to prevent secondary human transmission. We illustrate these measures with the case of Geneva. Healthcare professionals play a critical role in managing this emerging public health risk. Early diagnosis of these infections in returning travelers, adherence to recommendations for individual protection in suspected cases of arboviral disease and public health measures help reduce the risk of local transmission.
