There have been 13 reported cases of West Nile virus in humans in Ottawa so far in 2017 — the most since the virus made its first appearance in Canada in 2001.
Before this summer, the highest number of West Nile cases was eight in 2012, said Ottawa Public Health on Wednesday. But with temperatures at summertime levels over the past week and hot weather predicted into next week, public health officials warn that virus-carrying mosquitoes will continue to bite until there have been several hard frosts.
