The mosquito-borne Zika virus can cause the birth defect microcephaly, which can cause babies to be born with unusually small heads and deformed brains. In Europe, the potential threat of Zika comes from a mosquito related to Aedes aegypti (pictured) -- Aedes albopictus -- which began to spread in southern Europe about 25 years ago.
