The Saskatchewan Health Authority is warning residents in southeastern Saskatchewan that the risk of West Nile virus infection is increasing. This past week, some of the mosquitoes (Culex tarsalis) caught in surveillance traps were found to be infected with West Nile virus.
The provincial mosquito surveillance program identified the infected mosquitoes in traps collected on July 10 in the Estevan area. This positive pool is occurring a few weeks earlier than 2016 but about the same time as 2017. It is expected that there may be an increase in the number of pools, increases in infection rates and possible human infections.
To reduce your risk of infection, residents are advised to take precautions to reduce infection from West Nile virus throughout the rest of the summer.
“All people in the region need to prevent infections by getting rid of mosquito-friendly places in their yards and taking personal precautions to avoid being bitten by mosquitoes in the places where they live, work and play,” says Dr. Lanre Medu, Medical Health Officer with the Saskatchewan Health Authority in Weyburn. “People who work outside, especially at dusk and dawn, and those who are camping over the next few weeks are at higher risk of being bitten by mosquitoes and should pay particular attention to preventing these bites.”
While the risk due to Culex tarsalis mosquito is increasing, there is no need for adult mosquito control now. For more information on West Nile Vile, see the
