Grand Erie Public Health is notifying the public of a potential exposure to chickenpox (varicella) at Brantford General Hospital on Friday, November 6, 2026.
Individuals who visited Brantford General Hospital’s emergency department waiting room between 10:23 a.m. and 10:36 a.m. as well as the zone 7 waiting room from 10:36 a.m. to 12:26 p.m. on Friday, Nov. 6, 2026, may have been exposed to chickenpox.
Chickenpox is a highly contagious infection caused by the varicella-zoster virus (VZV). Since the introduction of routine vaccination, cases have become uncommon. Symptoms typically include fever, fatigue, and an itchy rash that progresses to fluid-filled blisters. Symptoms usually develop 14 to 16 days after exposure.
Most people who have had chickenpox or received two doses of varicella vaccine are protected against infection. However, some individuals are at greater risk of serious illness, including:
- Infants under one year of age
- Pregnant individuals who are not immune
- People with weakened immune systems
- Individuals who have never had chickenpox or have not been vaccinated
Grand Erie Public Health is advising anyone who may have been exposed during the identified timeframe to monitor for symptoms until November 27 (21 days post exposure). High-risk individuals who fall under any of these above categories are encouraged to follow up with their primary care provider or visit a walk-in clinic as soon as possible for assessment. If you don’t have a primary care provider, you can access care at the Primary Care Access Clinic by calling 226-388-4725 or by booking an appointment with the Virtual Urgent Care Clinic at www.urgentcareontario.ca.
