Cooler weather significantly decreases risk of additional cases
One Saskatchewan resident has been hospitalized due to West Nile neurological syndrome and six others are under investigation for West Nile Virus infections.
The recent cases likely became infected during the last weeks of August and early September. The risk level is now low.
Most people who become infected with West Nile Virus experience no symptoms or mild illness such as fever, headaches and body aches. However, there is a small risk of the more serious West Nile neurological syndrome. This includes encephalitis, an inflammation of the brain.
“People who develop symptoms such as severe headaches, persistent high fever or confusion should seek medical attention immediately,” Saskatchewan’s Chief Medical Health Officer, Dr. Saqib Shahab said. “However, we are nearing the end of the summer season, and the risk of West Nile Virus has gone down significantly.”
With the onset of cooler weather, the number of Culex tarsalis mosquitoes which carry West Nile Virus have been dropping. The risk to humans from West Nile Virus has decreased substantially, and will remain minimal to low for the rest of the season.
