Health officials say there is no current risk of Zika transmission after mosquito larvae from a species linked to human cases of the virus were found in the Windsor, Ont., area.
Officials had enhanced their mosquito surveillance efforts after finding four Aedes albopictus mosquitos, a species capable of transmitting the virus, last month.
They collected larvae as part of that surveillance and three larvae grew into Aedus aegypti mosquitos, the species responsible for the majority of human cases of the virus in the Caribbean, South America and Florida.
All the mosquitos tested negative for Zika.
Local medical officer of health Dr. Gary Kirk says he believes it's the first time that type of mosquito has been found in Canada.
He says it's not clear how the larvae arrived, but eggs could have been carried over in shipping containers coming from the U.S.
