Aedes aegypti is currently the mosquito with major impact on public health in Brazil and a proven vector of several emerging arboviruses. By consequence, its name is frequently being spoken by lay people of the media and general public, as well as by researchers in this country both in general media and academic events. However, the generic name Aedes, contrary to its etymological origin and worldwide correct pronunciation (“A-e-des”), has been frequently mispronounced as “Edes” on many occasions by media spokespersons and by researchers and lay people in Brazil. However, based on historical and linguistic evidence, it is confi rmed here that the correct historical pronunciation (A-e-des) must be maintained and observed in Brazil as it is enunciated all over the World.
