The Incidence of Acute Gastrointestinal Illness in Canada, Foodbook Survey 2014-2015

الملخص EN

Acute gastrointestinal illness (AGI) is an important public health issue, with many pathogen sources and modes of transmission.

A one-year telephone survey was conducted in Canada (2014-2015) to estimate the incidence of self-reported AGI in the previous 28 days and to describe health care seeking behaviour, using a symptom-based case definition.

Excluding cases with respiratory symptoms, it is estimated that there are 0.57 self-reported AGI episodes per person-year, almost 19.5 million episodes in Canada each year.

The proportion of cases seeking medical care was nearly 9%, of which 17% reported being requested to submit a sample for laboratory testing, and 49% of those requested complied and provided a sample.

Results can be used to inform burden of illness and source attribution studies and indicate that AGI continues to be an important public health issue in Canada.
