A measles outbreak in Canada’s Ontario province continues to grow,
with health officials reporting more than 140 cases on Thursday [27
Feb 2025], making it the most severe outbreak in decades. Public
Health Ontario said in an update that so far in 2025, it has seen a
total of 119 confirmed and 23 probable cases of the highly infectious
disease, with all but 2 associated with an ongoing multijurisdictional
outbreak that began in the fall [2024].
The officials have traced the outbreak back to a travel-related case
in New Brunswick on October 18 [2024]. While the maritime province has
since declared its outbreak over, Ontario continues to battle
transmission. A total of 177 cases have been reported in Ontario going
back to October 2024, but infections have spiked since the middle of
January 2025.
Prior to the COVID-19 pandemic, the province saw between 7 and 22
cases a year, Public Health Canada said, with 101 confirmed cases
reported between 2013 and 2023. In 2024, there were 37 cases
associated with the ongoing outbreak, officials said.
