WINDSOR, Ont. – A health center in southern Ontario says that a mosquito of the species responsible for most Zika cases worldwide was captured in Canada for the first time but did not carry the virus.
The Windsor-Essex County Health Center claims that one of its mosquito traps recently caught an adult insect of the species Aedes aegypti, and that a larva of the same species was also discovered last year In the region.
The center said Zika’s tests on adult mosquitoes and larvae were negative.
Aedes aegypti mosquitoes can carry several other tropical diseases such as dengue fever, yellow fever and chikungunya.
They are commonly found in tropical climates, particularly in the southern United States, but some specimens have been found much further north to the state of Michigan.
The Windsor-Essex Health Center was unable to explain how this adult mosquito ended in the area.
Curtis Russell, an expert on mosquito-borne diseases, points out that the population of Aedes aegypti in Canada is too small to cause serious epidemics.
He maintains that the main cause of infection for Canadians remains travel to the affected areas.
