Researchers at the University of Helsinki have discovered the mosquito species Anopheles daciae in several regions of Finland. The species is closely related to other malaria-spreading mosquitoes and is considered a potential carrier of the disease. However, malaria died out in Finland in the 1950s, and there is no immediate risk of it spreading. The researchers stress the importance of tracking all mosquito species in Europe that can transmit pathogens, including malaria, particularly in light of the effects of climate change.
