WEST NILE VIRUS BULLETIN #11
- Twenty-two additional probable human cases of West Nile virus infection have been identified in Manitoba, bringing the total number of West Nile human cases to 45--two confirmed and 43 probable.
- Of the 23 cases that have been classified, eight cases are West Nile virus neurological syndrome, and 14 are West Nile virus fever. One case, discovered through the testing of donated blood by Canadian Blood Services, has been reported as an asymptomatic case of West Nile virus. The 22 additional cases announced today are yet to be classified. In addition, Manitobans continue to be assessed for West Nile virus and testing is ongoing.
- Although mosquito counts are generally lower, there are still infected mosquitoes in southern Manitoba that may be active, particularly in warmer weather. At this time of year, mosquitoes are more active in the late afternoon and early evening.
- All Manitobans, especially those over the age of 50 or with chronic medical conditions or weakened immune systems, are advised to:
- reduce the amount of time outdoors in the afternoon and early evening when mosquitoes are now most active;
- wear light-coloured, loose-fitting, long-sleeved shirts and long pants when outside;
- use insect repellent containing DEET; and
- check that door and window screens fit tightly and are free of holes.
