Measles cases continue to rise across the Southwestern Public Health region, with 451 confirmed cases reported since October 2024, according to an update from Medical Officer of Health Dr. Ninh Tran on Thursday, May 1st.
That figure includes 65 new cases added in the past week alone.
While the increase may raise concerns, Dr. Tran emphasized that most of the newly reported infections are connected to a single outbreak currently under investigation.
Clusters of cases have emerged in large households, among siblings and family members, and at events where unvaccinated people are present.
Dr. Tran also warned that measles can be contagious before the hallmark rash appears—often leading to unintentional spread.
Symptoms can develop up to 21 days after exposure, and individuals remain contagious until five days after the rash appears.
Southwestern Public Health continues to encourage all eligible residents to ensure their measles vaccinations are up to date.
