Public‑health alert for visitors and patients after two exposure days
York Region Public Health has issued an advisory after confirming that a person with measles was at Cortellucci Vaughan Hospital on two separate days in August. The agency says the individual was in emergency waiting areas and ambulatory care during specified time windows on Aug. 17 and Aug. 21, and anyone present at those locations during the listed times may have been exposed.
The public-health notice identifies the following exposure windows at Cortellucci Vaughan Hospital:
| Date | Location | Time |
|---|---|---|
| Aug. 17 | Emergency waiting room | 8:40 p.m. to 10:40 p.m. |
| Aug. 17 | Emergency room ambulatory care | 9:30 p.m. to 11:59 p.m. |
| Aug. 21 | Emergency waiting room | 10:00 a.m. to 12:15 p.m. |
| Aug. 21 | Emergency room ambulatory care | 11:10 a.m. to 6:30 p.m. |
Who should act, and what to do next
York Region Public Health is asking anyone who was at those hospital locations during the listed times to confirm whether they have received two doses of a measles‑containing vaccine. The agency also requests that potentially exposed people complete a follow‑up survey on the York Public Health website to help assess their individual risk.
- Confirm vaccination status — particularly whether you have two documented doses.
- Complete the follow‑up survey on the York Public Health website as instructed in the advisory.
- Monitor for symptoms through the end of the relevant incubation windows: until Sept. 7 for those exposed Aug. 17, and until Sept. 11 for those exposed Aug. 21.
Measles is a viral infection that can spread easily in health‑care settings. York Region Public Health highlights the virus's ability to persist in the environment, noting:
“Measles is a highly contagious viral infection and the virus can live in the air or on surfaces for up to two hours.”
Symptoms generally appear between seven and 21 days after exposure and may include a high fever, cough, runny nose, red watery eyes and a red rash that usually appears three to seven days after other symptoms begin. Anyone who develops these symptoms and has a possible exposure should contact public health or their health‑care provider for guidance rather than attending health facilities without prior notice.
Local context and implications
The advisory follows York Region Public Health’s standard practice of notifying the public about potential exposures in shared spaces, particularly in hospital settings where vulnerable people may be present. For Vaughan residents, the notice underscores the importance of vaccination records ahead of routine or emergency care, especially in congregate settings.
Health officials have not disclosed additional details about the case in order to protect patient privacy. This advisory does not indicate an outbreak but serves to identify possible contacts and limit further spread. Completing the public‑health survey will help authorities with contact tracing and risk assessment.
Residents who are unsure about their vaccination history can check personal health records, consult a family physician or contact York Region Public Health for information on how to verify immunization status and obtain catch‑up vaccination if required.
York Region Public Health continues to post updates and instructions on its website for anyone who believes they may have been exposed or who develops symptoms compatible with measles.
