Alberta Health Services is warning people who were at three restaurants in Calgary, and one in Banff, that they may have been exposed to the measles virus earlier this month.

AHS issued the warning as it confirmed Calgary's eighth case of measles this year. 

Asian Buffet, 9125 Bonaventure Dr. S.E., Calgary

  • April 8: 11 a.m. to midnight
  • April 10: 11 a.m. to midnight
  • April 11: 11 a.m. to midnight
  • April 12: 11 a.m. to midnight
  • April 13: 11 a.m. to midnight
  • April 15: 11 a.m. to midnight
  • April 17: 11 a.m. to 6 p.m.

Long’s Chinese Food, 1448 17th Ave. S.W.,  Calgary

  • April 9: 6-10 p.m.

Castello Ristorante, 405 Spray Ave., Banff 

  • April 14: 8-11:30 p.m.

South Silk Road Chinese Restaurant, 823 14th St. N.W., Calgary

  • April 16: 3:30-7 p.m.

The locations include the Castello Ristorante in Banff, as well as the Asian Buffet, Long's Chinese Food and the South Silk Road Restaurant in Calgary. 

AHS says anyone who visited those locations at those times may be at risk for developing measles. 

Those individuals are advised to monitor themselves for symptoms of the highly-contagious disease, which could include fever, cough and a blotchy red rash that appears several days after the fever, beginning on the face and behind the ears and moving down the body.

AHS is asking anyone showing those symptoms to stay home and call Health Link Alberta at 1-866-408-5465 before visiting any health-care facility or provider.

Officials also said the most recent case is not travel or school related, and the person who contracted measles was likely not immunized. The person worked at the Asian Buffet on Bonaventure Drive southeast on several dates from April 8-17, say health officials.

In Edmonton, a fifth measles case has been confirmed in an infant under 12 months old.

Earlier this week in Red Deer, 40 students and eight staff members at Mattie McCullough Elementary were told to stay home after being exposed to someone who came down with the disease.

Some Calgary students at Henry Wise Wood High School and Sherwood School were also asked to stay home earlier this month after one student in each school was diagnosed with measles.

Those cases were related to travel to the Philippines.  

AHS officials say the outbreak of measles in the province underscores the importance of immunization.

Dr. Glen Armstrong of the University of Calgary says measles is highly infectious for those who haven't been immunized. He says the measles virus can hang around in the air for hours after an infected person has left.
