Most recent data from its West Nile Virus Surveillance program, which focuses on mosquito trapping and testing, indicate five mosquito pools have tested positive for West Nile – two in Cayuga and one in each of Simcoe, Dunnville and Caledonia.
The health unit says, “The positive human cases and positive mosquito pools is a clear indication that [the] threat of West Nile virus is present within our region and the public must take measures to protect themselves.”
