Toronto Public Health reports first human case of West Nile virus in Toronto for 2019

Toronto Public Health has received laboratory confirmation of Toronto’s first reported case of West Nile virus for 2019 in an adult resident. West Nile virus is an infection transmitted to people through the bite of an infected mosquito.

While the risk of getting infected in Toronto remains low, Toronto Public Health advises residents to take these precautions to avoid bites from infected mosquitoes:
• Wear light-coloured clothing, long pants and long-sleeved shirts when outdoors.
• Apply insect repellent containing DEET or icaridin and follow the manufacturer’s instructions.
• Take extra care during peak mosquito-biting hours, dusk and dawn, by using repellent and covering up.
• Make sure your home has tight-fitting screens on windows and doors.
• Remove standing water from your property, where mosquitoes can breed. Standing water includes any water that collects in items such as buckets, planters, toys and waste containers.

West Nile virus symptoms usually develop between two and 14 days after a person is bitten by an infected mosquito. Symptoms may include fever, headache, nausea, vomiting, body aches, skin rash and swollen lymph glands. Older individuals or individuals with compromised immune systems are at higher risk of severe illness. If you or a family member has concerns about any symptoms, contact your health care provider.

In 2018, 39 laboratory-confirmed human cases of West Nile virus and 40 positive mosquito tests were reported to Toronto Public Health.

  1. Did you know, Dragon Flies actually eat these pesky mosquitoes? Dragonflies are predators, both in their aquatic larval stage, when they are known as nymphs or naiads, and as adults. The loss of wetland habitat threatens dragonfly populations around the world.

    Think about it. I have reiterated many times how we as humans continually try to solve one problem but end up creating another. Pesticides have also been both boon and a bane in our lives. In most cases it remains the latter.

    I am not implying we should stop doing what we can to prevent the spread of West Nile Virus and other insect borne diseases, but old Mother Nature should obviously included in our plans.

    1. Furthermore, many people are unaware that ONLY the female of most species has tube-like mouth parts (proboscis) that pierces the skin of a host (referred to as a bite) and imbibes blood, which contains protein and iron needed to produce eggs.

      So following the above mentioned precautions to prevent these female blood suckers from draining the life out of humanity, is well worth the effort.

      But please, be kind to those Skeeter Eaters !
