Concerns are mounting as the number of measles cases in Canada continues to rise. In Quebec, the current outbreak has grown to 31 cases. Pediatric infectious diseases expert at the Montreal Children’s Hospital, Dr. Earl Rubin, joins Global News Morning’s host Laura Casella with more.

The warning applies to people who were at the Canadiens-Sabres game between 5:30 p.m. and midnight, in red sections 111 to 117, as well as employees of Tim Hortons and Pizza Pizza stands at the Bell Centre.

“Measles contacts who are not protected against this disease are recommended to isolate themselves at home until March 17 inclusive,” public health said in a statement on Monday.
