Anyone who was on a trip with Cold Shot Bus Company from Calgary to north of Edmonton on March 10 and 11 is being warned of a potential measles exposure. An initial exposure was identified at the Calgary Airport at baggage claim carousel #4 at 4:45 p.m. It then extended to the Calgary Bus Terminal beginning at 6 p.m., according to a news release from the Alberta government. From there, exposures line up with stops along the trip at the Red Deer Bus Terminal and Edmonton Bus Terminal. A second trip from the Edmonton terminal to a Grande Prairie terminal, which traveled overnight into March 11, was also listed as an exposure risk. A full list of exposure time periods can be found on the Alberta government website. People who were in these areas during these times, were born in 1970 or later, and have fewer than two documented doses of measles-containing vaccine or have never had measles could be at risk of developing the illness. Measles is highly contagious and includes a fever of 38.3 C or higher, a cough, runny nose and red eyes as well as a rash that can appear three to seven days after your fever starts, usually beginning behind the ears, on the face and spreading down the body. If symptoms of measles do develop, health agencies ask that you stay home and call the measles hotline at 1-844-944-3434 before visiting any health-care centres.
