Calgary Faces Shigella Outbreak Among Homeless Population

An outbreak of shigella is currently affecting Calgary‘s homeless population, sending at least 16 individuals to the hospital. This gastrointestinal illness has proven to be highly contagious, and health officials are scrambling to contain its spread.

Since the outbreak was declared on June 5, a total of 63 people have tested positive for shigella. Of these, 28 have been hospitalized, with 16 needing a hospital stay directly due to the illness. Unfortunately, 12 others who were hospitalized for different medical reasons have also tested positive.

Dr. David Klassen, a medical officer of health with Alberta Health Services, explained that the focus of the outbreak began in shelters but has now spread to those living outdoors. Symptoms of shigella include diarrhea (often bloody), abdominal cramps, fever, and vomiting, though many people recover on their own. However, serious complications like severe dehydration can occur.

Transmission of shigella is easy, especially in overcrowded or unsanitary living conditions. Dr. Klassen noted that people in homeless shelters often gather in groups, making it easier for the illness to spread. “It’s just challenges with meeting basic hygiene needs,” he remarked.

In response to the outbreak, Alberta Health Services has increased inspections at shelters and is providing guidance to ensure proper hygiene measures are in place. They are also offering support to individuals living in encampments.

Organizations like Alpha House are stepping up by distributing personal hygiene kits, which include water, hand sanitizer, wipes, and garbage bags. Nurse practitioner Patty Wilson expressed her deep concern for those affected, stating that many lack access to basic necessities like clean water and proper food.

This ongoing outbreak is part of a broader trend, with increasing cases of shigella reported across North America. Recently, a separate shigella outbreak was declared in the Maskwacis area, with no connections to Calgary’s situation identified.

Dr. Lynora Saxinger, an infectious diseases expert, highlighted the troubling increase in cases in crowded urban settings like Calgary. She feared that unless effective measures are taken, this outbreak could turn into a long-term issue, similar to what has been seen in Edmonton.
