Wellington-Dufferin-Guelph Public Health is seeing measles begin to circulate in the area, confirming a local case.
One case has also been reported from an individual from outside the region with a confirmed case of measles attended at an event in Guelph last month.
Public Health is following up with anyone who may have been exposed to either case.
Dr. Nicola Mercer, Medical Officer of Health and CEO says this is part of a trend of increasing cases of measles identified in multiple jurisdictions across Ontario.
Public Health says vaccination remains as the best way to prevent measles with two doses being nearly 100 per cent effective at preventing measles.
