The South East Health Unit is urging residents to make sure their measles immunizations are up-to-date.
It comes amid the largest measles outbreak in the province in 30 years.
As of Wednesday, Ontario has reported a total of 372 measles cases associated with the outbreak occurring in 11 public health units.
That includes 32 measles cases in Hastings County where officials say none of the individuals involved were previously immunized.
They say ensuring your vaccines are up to date is the best way to protect yourself and your loved ones and reduce the spread of measles in our community.
