A measles exposure warning has been issued for one of Winnipeg’s busiest medical facilities — and if you visited the emergency department at Health Sciences Centre Winnipeg during a specific window of time, public health officials want you to act now.
Manitoba Health has confirmed that a person infected with measles was present in the emergency department waiting area at Health Sciences Centre Winnipeg. Because measles is among the most contagious infectious diseases known to medicine, anyone who shared that space during the exposure period is considered potentially at risk — even if they feel perfectly fine right now.
This alert carries real urgency. Measles can spread through the air and linger in a room for up to two hours after an infected person has left. In a busy hospital waiting room, the number of people potentially exposed can be significant.
What Manitoba Health Is Warning About
According to the official alert from Manitoba Health, individuals who were present in the emergency department waiting room at Health Sciences Centre Winnipeg on the affected dates are being asked to monitor themselves for symptoms of measles and to contact public health if those symptoms develop.
Health Sciences Centre Winnipeg is described as one of the province’s busiest medical facilities, meaning foot traffic through its emergency department is consistently high. That makes a confirmed measles exposure there a matter of broader public concern, not just for those who were sick and seeking care that day.
Officials have noted that the exposure has prompted a wider public health advisory, with Manitoba’s public health authorities urging residents to understand the symptoms and respond appropriately if they believe they may have been exposed.
Measles Exposure: What You Need to Know
Measles is not a minor illness. It spreads through respiratory droplets and airborne particles, and a single infected person can transmit the virus to up to 90 percent of unvaccinated people they come into close contact with. Symptoms don’t appear immediately — the incubation period typically runs between 7 and 14 days after exposure, though it can stretch to 21 days.
Knowing what to look for matters. Here are the key symptoms associated with measles:
- High fever, often the first sign to appear
- Persistent cough
- Runny nose
- Red, watery eyes (conjunctivitis)
- Small white spots inside the mouth, known as Koplik’s spots
- A red, blotchy skin rash that typically starts on the face and spreads downward
The rash usually appears three to five days after the first symptoms begin. By the time a rash is visible, the person has typically already been contagious for several days.

Who This Alert Affects Most
Anyone who was in the Health Sciences Centre Winnipeg emergency department waiting area on the specified dates should treat this alert as personally relevant — regardless of whether they were the patient, a companion, or a visitor.
Certain groups face significantly higher risk if they contract measles. These include infants and young children who have not yet been fully vaccinated, pregnant individuals, and people with compromised immune systems. For these groups, measles can lead to serious complications including pneumonia, encephalitis, and in rare cases, death.
Officials have emphasized that vaccination status is the critical factor here. People who have received two doses of the MMR vaccine are considered well-protected. Those who are unvaccinated, only partially vaccinated, or uncertain about their vaccination history are at meaningful risk and should take this warning seriously.
Travelers passing through Winnipeg are also included in this advisory. Health Sciences Centre is a major regional facility, and its emergency department serves patients from across Manitoba and beyond. If you were in Winnipeg around the exposure dates and visited the hospital, this alert applies to you regardless of where you live now.
What You Should Do Right Now
Manitoba Health’s guidance is clear: if you were in the emergency department waiting room at Health Sciences Centre Winnipeg during the exposure window, do not wait for symptoms to appear before taking action.
- Check your vaccination records. Two doses of the MMR vaccine provide strong protection. If you’re unsure, contact your healthcare provider.
- Monitor for symptoms for up to 21 days from the date of potential exposure.
- Do not go to a clinic or emergency room if you develop symptoms without calling ahead first — this prevents further spread in healthcare settings.
- Contact Manitoba Health or your local public health office if you believe you were exposed and are experiencing symptoms.
- Isolate yourself if symptoms develop, as measles is contagious from four days before the rash appears through four days after.
Public health authorities have made clear that early identification and isolation are the most effective tools for preventing further spread from this exposure event.
The Broader Picture Behind This Alert
This warning comes at a time when measles cases have been rising in several parts of North America following years of disrupted vaccination schedules and growing hesitancy around routine immunization. A single imported or community case can quickly become a cluster when vaccination coverage gaps exist.
Manitoba Health’s decision to issue a public-facing alert rather than handle this quietly reflects how seriously officials are treating the potential for spread. Hospital waiting rooms, by their nature, bring together people who are already unwell, immunocompromised, or otherwise vulnerable — making them high-risk environments when an infectious disease case is identified.
The MMR vaccine remains the most effective protection available. Health officials across Canada consistently recommend that all eligible individuals ensure they are up to date on their vaccinations, particularly before travel or in response to alerts like this one.
