Human cases of West Nile Virus in Ottawa increased tenfold this summer, compared to 2016—the highest number Ottawa Public Health has ever recorded.
All told, there were 20 human cases of the mosquito-born virus this year— a figure that is greater than the total number of cases seen in the city since 2006.
“This year, as everyone knows, we came within a half millimetre of setting an all-time record for rainfall,” said Dr. Monir Taha, an associate medical officer of health at OPH. “The main driver this year was lots of water and sufficient temperature.”
