SWPH concludes weekly measles outbreak report

Amid an ongoing pattern of fewer measles cases reported to the health unit, Southwestern Public Health has concluded publishing its weekly Measles Outbreak Report until further notice.

Residents of Elgin County, Oxford County, and the City of St. Thomas are encouraged to view the weekly measles epidemiology report published by Public Health Ontario that captures the number of cases in the region that are connected to the ongoing provincial measles outbreak.

“The decision to end our local measles dashboard does not mean this outbreak has ended. Instead, we are recommending a provincial source to inform our community as we move through this outbreak response,” says Dr. Ninh Tran, Medical Officer of Health. “The risk of measles persists for those who are susceptible. Please continue to be vigilant in preventing measles and protecting yourselves and loved ones through vaccination.”

Epidemiologists at Southwestern Public Health routinely gather data to inform the local public health response to this outbreak. In April 2025, its weekly dashboard was published to provide community awareness about local measles cases and related hospitalizations.
