Summer in Canada is a precious thing. After months of cold and grey, we finally get to soak in the warmth, head to the cottage, lounge on patios, and enjoy late sunsets. But just as we start to lean into this short season, the unwelcome return of West Nile virus gives us a reason to pause if not panic.
In the past week, mosquitoes carrying West Nile have been detected in several parts of Ontario, including Toronto, York Region, and Welland in the Niagara Region. While no human cases have been reported yet this year, experts remind us that now is the time to stay cautious not scared.
Dr. Isaac Bogoch, infectious diseases specialist at Toronto General Hospital, summed it up well: “Nobody wants to get bit by mosquitoes, whether or not they’re causing fever.” He’s right. Mosquitoes are the unofficial pests of summer, and this virus just gives us another reason to be wary of them.
West Nile virus isn’t new it first appeared in Canada in 2002. It spreads when mosquitoes feed on infected birds and then bite humans. Most people who get it around 70 to 80 per cent don’t even show symptoms. For those who do, symptoms can resemble a bad flu: fever, headache, body aches, maybe a rash or swollen glands. Not fun, but generally manageable.
It’s the rare severe cases less than one per cent that can become dangerous. We’re talking about inflammation of the brain, high fever, confusion, even paralysis. And while these cases are uncommon, they can be serious, especially for older adults or those with chronic conditions. According to the Public Health Agency of Canada, a small percentage of those who develop severe symptoms may not survive.
Still, the risk of West Nile virus shouldn’t send us indoors or into a panic spiral. Canada’s public health experts aren’t sounding alarms they’re just offering practical advice. Cover your skin when mosquitoes are most active (dawn and dusk), wear light-coloured clothing, and use insect repellent with DEET or icaridin. And don’t forget the simplest defense: remove standing water from around your home, where mosquitoes love to breed.
Yes, West Nile is back but so is summer. And that’s not something to waste. The message is clear: enjoy the season, just be smart about it. As Dr. Bogoch put it, “No reason to hide indoors because of this. Just go outside, have a wonderful time, be aware that they’re there.”
In other words, don’t let the buzz ruin your summer vibes.
