Since 2018, mosquito monitoring has been carried out at Vienna International Airport in order to determine whether exotic and potentially invasive mosquito species are being introduced into Austria via air traffic. Special attention is paid to the Asian tiger mosquito. These mosquito species are potential vectors of a variety of pathogens and thus pose a threat to public health. This project aims to detect the presence of these species at the airport at an early stage, enabling timely countermeasures to be taken.
