Sporadic influenza activity reported in some regions of the country During weeks 39 and 40, sporadic activity was reported in British Columbia, Alberta and Ontario, while the rest of the country reported no activity (see map). From weeks 39 to 40, 3 (0.1%) of the 2,143 specimens tested for influenza virus were positive for influenza virus (see table). The first influenza B virus detection for the season was detected in Alberta in week 40. The ILI consultation rates remained low: 9 per 1,000 patient visits in week 39 and 7 per 1,000 patient visits in week 40 (see ILI graph). ILI consultation rates for weeks 39 and 40 were highest among children in regions reporting ILI activity. There have been no influenza outbreaks reported so far this season. Note: Subsequent findings confirmed that the school outbreak previously reported in week 37 was not due to influenza. In addition, since the start of the season no positive influenza laboratory detections have been reported in the region where the school is located.
