Alberta Silent on Measles Risks to Pregnant Patients Amid Outbreak

Alberta’s response to a measles outbreak has raised serious concerns regarding the health risks posed to pregnant individuals. The outbreak, which began in late October 2024 after an infected traveler arrived in New Brunswick, quickly spread across Canada. By March 2025, cases had reached northern Alberta, leading to a troubling statistic: the province reported more measles cases than the entire United States, despite having a population of just 5 million compared to 342 million in the U.S.

The situation worsened when, in October 2025, it was revealed that a baby in Alberta had died from congenital measles. This tragic event marked a significant turning point, prompting the Pan American Health Organization to revoke Canada’s measles elimination status in November 2025, a status the country had maintained since 1998. As vaccine hesitancy grew and vaccination rates plummeted, Alberta’s health officials faced criticism for their silence regarding the outbreak’s impact on pregnant patients.

Rising Concerns Among Pregnant Patients

As a family doctor in Alberta, I frequently encountered worried pregnant patients seeking guidance on measles during their visits. They expressed concerns about the potential risks, including pregnancy loss, sick newborns, and stillbirths. Despite the historical elimination of measles prior to my medical training, these outcomes were well known to me.

Questions flooded in from expectant parents about the safety of hospital visits and whether travel was advisable. In July 2025, hospital policies reflected growing risks when signs were posted limiting support visitors in high-risk areas, including labor and delivery. Yet, throughout mid to late 2025, I found myself questioning why there was a lack of available data on obstetrical outcomes related to the outbreak.

Alberta’s health authorities published daily updates on confirmed measles cases, but information specifically regarding pregnant individuals appeared to be missing. A report by the Canadian Broadcasting Corporation in June revealed that twenty pregnant Albertans had been infected, but there was no internal communication from health officials to inform healthcare providers.

In an effort to obtain crucial information, I submitted an Access to Information Request on September 18, 2025. My inquiry sought to uncover the number of confirmed measles cases in pregnant women since March 1, 2025, including hospitalization rates, instances of preterm labor, diagnoses of congenital measles, and any occurrences of stillbirth or neonatal deaths.

Data Access Challenges and Lack of Transparency

After receiving advice to refine my request, I aimed for all communications between Alberta Health Services, Primary Care Alberta, and the Ministry of Health regarding maternal and perinatal outcomes related to measles from March to August. Two months later, I was provided with a file containing twenty-six pages of emails, but much of the relevant information was redacted.

One email from June revealed an epidemiologist’s concerns about reported cases related to pregnancy, while another mentioned instances of illness occurring shortly after delivery. The heavily redacted records indicated that while officials tracked adverse outcomes, they hesitated to release clear information to the public and medical professionals.

Despite the lengthy wait for the information, the findings did not provide the clarity needed to inform patients effectively. Internal emails hinted at significant issues: one noted “43 pregnant cases” and “intrauterine fetal demise,” while another referenced additional miscarriages. Sadly, one email from September 17 confirmed an infant’s death, which appeared to be related to the outbreak.

The lack of timely public announcements surrounding these deaths and complications has been frustrating, particularly given the province’s apparent understanding of the outbreak’s implications for vulnerable populations. Internal discussions indicated that there were ongoing conversations about how to report adverse outcomes formally, yet no substantial information was made available to the public.

In late November 2025, shortly after losing measles elimination status, Alberta introduced Bill 11, which aimed to allow more healthcare providers to offer services in private settings. The legislation was expedited, highlighting the province’s willingness to act quickly when it came to restructuring healthcare systems, yet it failed to prioritize transparency during a public health crisis.

The ongoing measles outbreak in Alberta serves as a stark reminder of the importance of clear communication in public health. With documented cases of harm to pregnant individuals and newborns, the lack of timely data sharing raises serious ethical concerns about the responsibilities of health officials to protect the health of their citizens.
