PHO Rounds: Epidemiology - Describing carbon monoxide exposures in Ontario

Type: PHO Rounds: Epidemiology
Format: In Person; Webinar

Please note: This is an open invitation and may be forwarded to interested parties.

Carbon monoxide (CO) poisoning creates a significant public health burden that is entirely preventable. In order to inform successful prevention strategies around CO poisoning, routine surveillance of CO exposures can help us understand how these events occur and how to identify the population at risk.

In Ontario, the Technical Standards and Safety Authority (TSSA) conducts detailed investigations following CO incidents involving emergency services. TSSA data provide unique information on the circumstances that result in CO exposures, which may be useful to public health practitioners wishing to address this important environmental health risk during winter months.

In collaboration with the TSSA, Public Health Ontario has reviewed 10 years of investigation data [2007-2016] to identify and understand predictors of CO incidents and at risk populations. This presentation will highlight our results and discuss our findings in the context of previous research in the area of CO exposures.

By the end of this session, participants will be able to:

  • Describe how the Technical Standards and Safety Authority collects information on CO incidents/exposures in Ontario;
  • Explain the most common causes of CO incidents/exposures in Ontario;
  • Identify additional data sources that could inform CO surveillance in Ontario.

Presenter: Elaina MacIntyre
