Grand Erie Public Health (GEPH) is warning residents of a potential measles exposure at a public event in Norfolk County earlier this month. Individuals who attended the Eat & Drink Norfolk event at the CIBC Auditorium, Building #9, located at the Norfolk County Fairgrounds (172 South Dr., Simcoe) on April 5, 2025, between 6:30 p.m. and 9 p.m., may have been exposed to the virus.
GEPH is urging anyone born in or after 1970 who has not had a measles infection or received two doses of a measles-containing vaccine to assess their risk. These individuals are considered susceptible and could develop symptoms if infected.
Those who may have been exposed are asked to complete the measles exposure form available at www.geph.ca/measlesform to help public health officials evaluate the risk and provide guidance.
Post-exposure options are available on a limited timeline:
- Within 72 hours: A dose of the measles, mumps, rubella (MMR) vaccine may help prevent infection.
- Within 6 days: Susceptible individuals at higher risk—such as infants, pregnant people, and those with compromised immune systems—may qualify for immunoglobulin to reduce severity or prevent illness.
GEPH has published additional information about symptoms, prevention, and support resources at www.bchu.org/measles and www.hnhu.org/measles.
The warning comes amid rising concerns over measles activity across Ontario. GEPH, which formed in January 2025 following the merger of the Haldimand-Norfolk Health Unit and Brant County Health Unit, serves communities across the County of Brant, City of Brantford, Haldimand County, and Norfolk County.
Officials remind the public that vaccination remains the most effective protection against measles—a highly contagious virus that can lead to serious complications, particularly in young children and vulnerable populations.
Anyone with concerns or symptoms, such as fever, cough, runny nose, or a red blotchy rash, is advised to contact their health provider and avoid public spaces until they receive medical advice.
