First 2006 human cases of West Nile virus found in Alberta
Edmonton...West Nile infection has been reported in two people; one in Palliser Health Region and another in Chinook Health. They were confirmed positive by the Alberta Provincial Laboratory for Public Health.
Both cases are in adult females and have symptoms of West Nile non-neurological syndrome, also called West Nile fever. In addition, an asymptomatic case has been detected in Chinook Health through Canadian Blood Services donor screening. This case is waiting for laboratory confirmation.
"The Culex mosquitoes that carry the West Nile virus are at the peak of their activity right now," said Dr. Karen Grimsrud, Deputy Provincial Health Officer. "It is important for people to take precautions to reduce their risk of being bitten. Use a repellent containing DEET, and wear clothing that covers arms and legs, including socks, especially at dawn and dusk when mosquitoes are most active."
Although the risk of serious illness is low, the effects of infection can be severe and long-lasting in a small number of those infected. Most people who contract West Nile show no symptoms at all and the virus runs its course. Fifteen to 20 per cent of cases suffer flu-like symptoms: fever, sore muscles and fatigue. In less than one per cent of cases, victims experience severe headaches, nausea, vomiting, weakness, numbness and paralysis. The risk of serious illness increases with age, particularly over the age of 50.
Since 2003, including these cases, Palliser Health Region has recorded 138 cases of West Nile infection while Chinook Health has had 40 cases.
