Health Services Alberta issued a fifth flu outbreak alert for Calgary.

Concerns about a potential fifth-generation flu outbreak in Calgary have been raised by Alberta Health Services. The flu may spread in crowded public areas, the AHS says. The health authority warned those who took Air Canada flight AC206 from Vancouver to Calgary at 10:20 a.m. on November 23, arrived at Calgary International Airport's domestic arrivals area between 12:45 and 3:15 p.m. on the same day and visited the emergency room of Alberta Children's Hospital between 4 and 9:30 p.m. on November 24 and November 27 to be on the lookout for symptoms of a fifth-grade fever. Visitors to the sites during these hours, according to AHS, should make sure they have had the fifth flu shot and call HealthLink 811 with any questions or concerns.
