There is now one confirmed human case of West Nile virus in Waterloo region; although public health officials say the person who tested positive contracted the virus while outside the region.

It brings the number of positive tests from mosquitoes in Perth County to six.

The spray itself is very low in toxicity, according to a news release from the health department, and should not affect or harm local mammals, or even non-target insects.

"Everything does clear up, but it's not a fun illness to have".

It is not uncommon for infected mosquitoes and human cases to pop up this time of year, according to the Cuyahoga County Board of Health. Adults over the age of 50 are most at risk of serious health effects.

"It's important for people to be extra cautious and protect themselves against mosquito bites when outdoors this late in the season". Some infected people will experience flu-like symptoms.

Those with symptoms of West Nile virus, such as high fever, vomiting, appetite loss, headaches and muscle aches, for two to 15 days after a mosquito bite should seek medical attention, the board of health said. In 2006, 4,269 confirmed human WNV cases were reported nationally to the Centers for Disease Control and Prevention; California reported 278 cases.
