Measles Exposure Alert at Stollery Children's Hospital Issued by Alberta Health Services
Alberta Health Services has issued a critical public health warning regarding potential measles exposure at multiple departments within the Stollery Children's Hospital. The alert comes after a confirmed exposure incident occurred on April 4, 2026, raising concerns about possible transmission of this highly contagious disease.
Exposure Details and Timeframes
The potential exposures took place at two key hospital departments during specific time periods. According to an official news release from Alberta Health Services, the emergency department experienced exposure from 4:17 a.m. to 10:40 p.m., while the X-ray department had exposure between 7:16 p.m. and 11:04 p.m. on April 4, 2026.
Health officials emphasize that anyone who visited the Stollery Children's Hospital during these timeframes should be particularly vigilant about monitoring for symptoms and reviewing their immunization status.
At-Risk Populations and Recommendations
Individuals born in or after 1970 who have fewer than two documented doses of measles-containing vaccine, or who have never had measles, are considered at elevated risk for developing the disease. Alberta Health Services strongly recommends that these individuals take additional precautions when presenting to healthcare facilities and carefully monitor for symptoms.
The health authority has identified several specific recommendations for those potentially exposed:
- Review immunization records immediately
- Monitor closely for measles symptoms
- Consider vaccination within 72 hours of exposure if not previously vaccinated
- Special populations including babies under one year old, immunocompromised individuals, and pregnant persons may qualify for immunoglobulin treatment within six days of exposure
Measles Transmission and Current Outbreak Context
Measles represents an extremely contagious viral disease that spreads easily through airborne transmission. The current warning comes amid an ongoing measles outbreak across Alberta that has seen significant case numbers in recent years.
Edmonton has recorded 39 confirmed measles cases in 2026 alone, with two cases currently listed as actively communicable. This compares to 44 total cases documented throughout all of 2025, indicating that exposure incidents are outpacing previous year's numbers.
Across Alberta, approximately 243 measles cases have been reported in 2026, with three remaining communicable. Since the outbreak began last year, more than 2,000 cases have been documented throughout the province, highlighting the persistent public health challenge posed by this preventable disease.
Vaccination Resources and Contact Information
Albertans who are uncertain about their immunization history or that of their children can access vaccination resources through multiple channels. The measles hotline at 1-844-944-3434 provides information about eligibility and facilitates appointment booking for those seeking vaccination or clarification about their immunization status.
Health officials stress that vaccination remains the most effective preventive measure against measles transmission. The measles, mumps, and rubella (MMR) vaccine provides robust protection when administered according to recommended schedules, typically requiring two doses for complete immunity.
This latest exposure warning follows similar alerts issued recently for healthcare facilities in Fairview, Edmonton, Calgary, Red Deer, and Grande Prairie, as well as at the Strathcona Community Hospital. Sixteen measles cases have been confirmed so far in 2026 in connection with these various exposure incidents.
