Brantford, ON – Grand Erie Public Health is notifying the public of a potential exposure to chickenpox (varicella) at Brantford General Hospital, 200 Terrace Hill St, Brantford between July 21-22, 2026.
Individuals who visited the emergency department at Brantford General Hospital between 11:53 p.m. on July 21 to 2:48 p.m. on July 22, 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 August 11-12 (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.
Anyone who develops symptoms such as fever or a rash should:
- Stay home and avoid contact with others, particularly those at higher risk of severe illness;
- Contact a healthcare provider before attending in person so appropriate precautions can be taken; and
- Call ahead before visiting a clinic, urgent care centre or emergency department.
Most adults over the age of 50 have previously been exposed to chickenpox and are considered immune. Individuals who are unsure of their immunity status or who may be at increased risk of complications are encouraged to consult their primary healthcare provider or contact the infectious disease team at Grand Erie Public Health at 519-753-4937 ext. 6440.
