There have been no new measles cases reported in Waterloo region, Guelph or Wellington County since July 8, new numbers from Public Health Ontario show.

In the update released Thursday, it shows total case numbers as of July 15 as:

  • Region of Waterloo Public Health: 110 cases.
  • Wellington-Dufferin-Guelph Public Health: 71 cases.

Ontario saw a total of 32 new cases of measles in the past week with 19 of those reported by Huron Perth Public Health, which covers areas including Stratford, Clinton, Goderich and St. Mary's.

The measles outbreak in this province began last October when Public Health Ontario received a report of a travel-related case linked back to a social gathering in New Brunswick. Ontario's first outbreak cases were reported the week of Oct. 28, 2024.

As of July 15, there have been a total of 2,342 confirmed or probable measles cases in Ontario since the start of 2024, of which 2,276 are linked to the outbreak. There has been one death of an infant with measles.

At its peak in April and May, the outbreak of the highly contagious disease was generating more than 200 new cases weekly.

Measles is a highly contagious respiratory virus. Symptoms of measles include fever, a red blotchy rash, red watery eyes and cough. 

The risk of contracting measles for individuals who are fully immunized, with two doses of a vaccine, or born before 1970, is considered very low.
