The province's first West Nile Virus-positive Culex tarsalis mosquitoes have been identified in the Estevan area. This species of mosquitoes continue to emerge throughout southern Saskatchewan and numbers are peaking in several localities. With rising numbers of Culex tarsalis, the risk of exposure to West Nile Virus is also expected to increase.
The Ministry of Health is reminding Saskatchewan residents to take protective measures against mosquitoes, as we enter the August long weekend and throughout the summer.
"We strongly encourage people to take personal precautions as the risk of exposure to West Nile Virus is increasing and people are spending more time outdoors," Deputy Chief Medical Health Officer Dr. Saqib Shahab said. "Residents can significantly reduce the risk of mosquito bites by using appropriate insect repellent, wearing protective clothing when outdoors and reducing the amount of time spent outdoors between dusk and dawn."
Mid July through August is typically the highest risk period for West Nile Virus due to a combination of factors: increasing numbers of Culex tarsalis mosquitoes, warmer weather, and people spending more time outdoors. The majority of people who have been infected with West Nile Virus will have no symptoms or only mild illness such as fever, headaches and body aches. However, the virus can result in serious neurological illness such as encephalitis (inflammation of the brain) which can have long-term complications and even cause death.
Updated Surveillance Results, Risk Maps and Weekly West Nile and Culex Reports are posted every Friday on the Ministry of Health's website at www.health.gov.sk.ca/west-nile-virus. Additional information on protective measures and the West Nile Virus (symptoms, when to seek help) are available on the Ministry of Health's website and Healthline Online at www.health.gov.sk.ca/healthline-online.
