Public Health Alert: Measles Exposure Notification for Calgary Emergency Departments

Public health officials have issued a formal notification regarding potential measles exposure at two major medical facilities in Calgary. Individuals who visited the emergency departments at the Foothills Medical Centre and the Alberta Children’s Hospital during specific windows in late May 2026 are urged to monitor their health for symptoms of the highly contagious virus.

Understanding the Exposure Risk

Measles is a serious viral infection that spreads easily through the air when an infected person coughs or sneezes. Because the virus can remain infectious in the air and on surfaces for up to two hours after an infected person has left a room, clinical settings—such as emergency departments—require strict protocols to manage potential transmission.

Health authorities are reaching out to patients and staff who may have been present during the identified exposure periods. If you believe you were at either facility during these times, it is essential to review your immunization history and remain vigilant for signs of illness.

Recognizing the Symptoms of Measles

Measles symptoms typically appear 10 to 14 days after exposure. Early signs often mimic a common cold or flu, making it critical to be aware of the following progression:

• Initial Symptoms: High fever, runny nose, cough, and red, watery eyes (conjunctivitis).
• The Rash: A characteristic red, blotchy rash typically appears three to five days after the initial symptoms begin. The rash usually starts on the face and hairline before spreading downward to the rest of the body.
• Koplik Spots: Modest white spots may appear inside the mouth before the skin rash develops.

If you or a family member develop these symptoms, do not go directly to a clinic or emergency department without calling ahead. Contacting health services by phone allows medical staff to prepare for your arrival, ensuring that you are isolated from other patients to prevent potential spread.

Key Takeaways for Public Safety

• Check Vaccination Records: Vaccination is the most effective way to prevent measles. Ensure that you and your children have received the recommended two doses of the measles, mumps, and rubella (MMR) vaccine.
• Monitor for Symptoms: If you visited the affected emergency departments, track your health closely for at least 21 days following the potential exposure.
• Seek Professional Advice: If you suspect you have been exposed and are experiencing symptoms, call your local health authority or a primary care provider immediately for guidance.

Frequently Asked Questions (FAQ)

What should I do if I am not vaccinated?

If you have not received the MMR vaccine or are unsure of your immunization status, contact your primary care provider or a public health clinic. Vaccination can sometimes provide protection if administered shortly after exposure.

Is measles dangerous?

While most people recover, measles can lead to severe complications, including pneumonia, encephalitis (brain swelling), and hospitalization. Vulnerable populations, including infants, pregnant individuals, and those with compromised immune systems, are at the highest risk.

Why is there an alert for emergency departments?

Emergency departments are high-traffic areas where people with weakened immune systems may be present. Alerts are issued to ensure that anyone who might have been exposed can take proactive steps to protect themselves and their community from further transmission.
