Alberta Health Services has issued an advisory after confirming a third case of measles in the Edmonton area. 

The case involves an Edmonton man who was treated in Redwater. Lab tests have only now confirmed that it was measles.  

Dr. Marcia Johnson, Chief Medical Officer of Health, said that the case is not linked to any other could be a concern.

"This person had no history of travel and no history of exposure to any of the other known places that he might have been exposed," she said. "That indicates that there is some measles circulating in the Edmonton zone."

Health officials say that anyone who was at Bon Accord Foods between 9:30 p.m. and 10 p.m. on Apr. 11 and the Redwater Health Centre between 10 a.m. on Apr. 13 and 8:30 p.m. on Apr. 15 may have been exposed to measles.

"We're asking them to watch out for any symptoms of measles that's a fever, cough, red eyes and a rash and if any of those symptoms develop to stay home and to call health link and ask for further instructions," Johnson said.

People who have not already had measles or have not received two doses of measles vaccine may be at risk of developing the disease.

If symptoms develop, people should stay home and call Health Link Alberta at 1-866-408-5465 before seeking medical attention in person.
