Simple precautions can prevent West Nile virus risk

    Alberta Health Services (AHS) is reminding Albertans to take simple, preventative measures to reduce the risk of West Nile virus this summer.     “The last few summers have seen very few confirmed cases of West Nile virus, which is a positive thing, but Albertans need to remain vigilant about protecting themselves from mosquitoes,” said Dr. Gerry Predy, Senior Medical Officer of Health for AHS. “West Nile virus can be a very serious illness that can have debilitating effects, particularly on older adults.”
    Symptoms of the most common form of West Nile virus (non-neurological syndrome) include fever, chills, nausea, vomiting, fatigue, a possible skin rash or swollen glands and headache. These symptoms usually occur within two to 14 days of infection; however, many people who become infected show no symptoms. A small number of infected people get the less common and more serious West Nile neurologic syndrome, which can cause tremors, vomiting, nausea, drowsiness, confusion, swallowing problems, high fever, decreased level of consciousness and/or paralysis.
    Dr. Digby Horne, Medical Officer of Health for the Central Zone of AHS, says wearing mosquito repellent with DEET, as well as long sleeves, pants and socks when outside are still the most effective prevention measures when dealing with West Nile virus.
    “Albertans and travellers need to use these protective measures when gardening, golfing, fishing or relaxing outdoors,” said Dr. Horne.
    The spread of the virus to humans is dependent on the activity of Culex tarsalis mosquitoes, which are typically most active during July and August, although their spread is dependent on the weather. The last few West Nile virus seasons have not been consistently warm enough to facilitate the spread of infected mosquitoes.
    Last year, there were five confirmed cases of West Nile virus in Canada; one in Alberta, a non-neurological case.
