First positive case of West Nile reported in Waterloo region


Two cases of human West Nile virus have been confirmed by Wellington-Dufferin-Guelph Public Health.

Despite the impending end of summer, the health unit recommends people still take the proper precautions.

WNV is transmitted through mosquito bites. Mosquitoes acquire the virus by feeding on infected birds.

Mosquitoes are the creatures more often infected with West Nile.

Public Health Inspector Stephanie Carlisle says this is usually the time of year many communities will find mosquitoes carrying the virus.

Harvey is expected to gradually weaken through the day on Sunday , though it's movement will remain fairly stationary. It looks like the system will make its closest approach to northeast SC later Monday or Monday night, DiGiorgi said.

Treating standing water with larvicide also can reduce the potential for West Nile virus transmission, according to the news release.

"It's important for people to be extra cautious and protect themselves against mosquito bites when outdoors this late in the season". During 2002, the state documented its first human infections and 52 cases were reported that year.

However, the health unit confirms the virus was found in mosquitoes located within a trap in Bradford West Gwillimbury. The number of people infected could even reach 2012 levels, when there were 457 positive surveillance pools and 271 human cases over the course of the year.

"We had a warm winter, we've had a cool, wet summer, and all that contributes to the possible- kind of ideal storm for West Nile virus in southern Ontario this year".
