Ontario, Canada: 2025 Measles

Fewer new measles cases in Ontario, public health data shows
Measles spread slowing
Nicole Ireland, The Canadian Press - Jul 3, 2025 / 2:28 pm | Story: 559750​

A Public Health Ontario report released Thursday suggests a continuing downward trend in new measles cases.

The health agency reported 12 new cases in the province, down from 33 additions last week and 96 the week before that.

Two more people were infected with the highly contagious disease in a northern region that includes Sault Ste. Marie and surrounding areas. That region had been showing the biggest increase in cases for a few weeks.

Meanwhile, four more people were infected in southwestern Ontario — the area that was hardest hit for months.

Public health officials acknowledged the declining trend but also noted that new cases still emerge weekly and that a reporting lag means it’s possible that infections from previous weeks have not yet been reported.

PHO explained that numbers will dip during an outbreak “as the proportion of susceptible people in communities become immune, through vaccination or infection.”

“PHO will continue to monitor measles data and activity closely in the coming weeks and months,” it said by email.

Ontario has had a total of 2,223 measles cases since an outbreak linked to travel in New Brunswick began last October.

Thursday’s report also deducted one case that had previously been reported in Wellington-Dufferin-Guelph. PHO would not reveal details, citing privacy reasons, but said some cases may be reclassified following an investigation.​..

New Ontario measles cases down to single digits for the first time since January
Aug 7, 2025 | 9:42 AM

TORONTO — Health officials in Ontario are reporting that the number of new measles cases are down to the single digits for the first time since January.

That’s based on weekly data release by Public Health Ontario, which shows eight measles cases reported over the past week, bringing the province’s total to 2,360 infections since an outbreak began in October.

The last time the province reported new cases in the single digits was on Jan. 16 when just two cases were added to the tally.

But as the outbreak expanded, health officials were at times dealing with hundreds of new infections per week.

The latest data shows most of the cases between July 29 and Aug. 5 were in Southwestern Ontario, Canada’s former measles hot spot.

Last month, the southwestern local public health unit reported no new cases for the first time since a spring surge.​..

Ontario reports a few new outbreak-related measles cases over the past week
The new cases bring Ontario’s total to 2,362 confirmed or probable measles cases since the multi-jurisdictional outbreak was declared on Oct. 18.

Ontario is continuing to see significantly lower numbers of new measles infections.

Public Health Ontario reported just three new outbreak-related cases over the past week in its Aug. 14 enhanced epidemiological summary. However, because of a reporting adjustment that removed a previously reported case, Ontario reported an overall increase of just two new outbreak-related cases.

The weekly summary includes information up to Aug. 12 at 7 a.m.​

The latest figures come a week after only eight new cases were reported Aug. 7, the first time in months Ontario saw a single-digit infection rate.

The most recently reported cases bring Ontario’s total measles case count (connected to a multi-jurisdictional and a travel-related outbreak first reported in New Brunswick on Oct. 18) to 2,362 cases (2,050 confirmed, 312 probable).

“While the downward trend in weekly case counts suggests that transmission may be slowing, continued vigilance is needed,” Public Health Ontario said in its summary.

So far in 2025, there have been 2,366 measles cases (2,080 confirmed, 286 probable) reported in Ontario — 41 of which weren’t linked to the multi-jurisdictional outbreak and are not included in the outbreak numbers.

The latest summary shows among all outbreak cases, 73.1 per cent were infants, children and adolescents, while 26.3 per cent were adults. The age of the remaining patients is unknown.​..
