Simple precautions reduce risk of West Nile virus infection

By Alberta Health Services Media Release

Alberta Health Services (AHS) is reminding Albertans to take precautions necessary to protect themselves against West Nile virus infection.
“With exposure to mosquitoes comes the risk of West Nile virus,” says Dr. Christine Kennedy, Medical Officer of Health, Calgary Zone. “Because some mosquitoes carry West Nile virus, it’s important to avoid being bitten at all.”
Whenever engaging in outdoor activities, or even just relaxing outside, all Albertans should take these simple steps to prevent bites and protect themselves from West Nile virus, including wearing a long-sleeved, light-coloured shirt, pants and a hat; using an approved insect repellant (e.g. products containing DEET or Icaridin); and staying indoors at dawn and dusk when mosquitoes are most active.
“These steps can make it harder for mosquitoes to find you. And remember: if mosquitoes can’t find you, they can’t bite you,” says Kennedy.
After being bitten by a mosquito carrying West Nile virus, humans can develop West Nile non-neurological syndrome (formerly known as West Nile fever) or the more serious West Nile neurological syndrome.
Symptoms of non-neurological syndrome can be uncomfortable, including fever, chills, nausea, vomiting, fatigue, skin rash, swollen glands and headache. For people who develop neurological syndrome, symptoms can be more severe, including tremors, drowsiness, confusion, swallowing problems, high fever, unconsciousness, paralysis and even death.
From 2003 to 2018, 532 cases of West Nile virus were confirmed in Alberta, many of which were acquired in the province and not travel-related. Of these cases, 458 were non-neurological syndrome.
