A study conducted by researchers at Brock University warns that Ontario is weeks away from a West Nile epidemic.
It suggests that with more than 250 mosquito pools having tested positive so far this year, including 19 in Hamilton, history shows that will lead to nearly 340 human cases.
That would put 2017 in line with 2012 as the worst outbreak years since 2002.
The warning comes as Hamilton’s West Nile Virus risk jumped on Monday from “moderate” to “high” after more mosquitoes in city traps tested positive for West Nile.
Scientist and mosquito researcher Fiona Hunter says, “We are well on our way to having a West Nile virus outbreak in Ontario.”
She adds even though some stores are clearing out their stock of mosquito repellent, “now is the time people should be putting on their insect repellent.”
The study was published Tuesday in the journal PLOS ONE.
West Nile virus is mainly spread to humans through the bite of an infected mosquito.
While most people who get West Nile do not experience any symptoms, a small number of individuals may develop flu-like symptoms such as high fever, severe headache, muscle weakness and stiff neck.
Anyone who suspects they have West Nile virus should seek medical attention.
