Illness/injury prevention
IWH has a long history of conducting research to provide practical guidance to employers, workers, OHS professionals and regulators about what works and what doesn’t in injury or illness prevention. This research targets the injury and illness prevention practices of workplaces, as well as the programs developed by governments, health and safety associations and others to support and motivate workplaces to adopt effective practices.

Refining estimates of occupational exposures and risk of workplace COVID-19 transmission
The COVID-19 pandemic shone a light on the importance of having accurate data on workplace exposure to infectious diseases. Efforts to estimate infection rates of COVID-19 during the public health emergency were hampered by inadequate information on key factors, such as whether an infected worker had worked from home or interacted with the public. In this presentation, Dr. Peter Smith shares results from a study that examined the risk of work-related COVID-19 infections. He discusses methods used by the team to combine data sources to take into account changes in labour market participation—including working from home—during different phases of the COVID-19 pandemic.
