COVID-19

COVID-19 was declared a global pandemic by the World Health Organization on March 11, 2020. In short order, the world of work changed dramatically in Canada. Non-essential businesses were locked down. Some workers lost their jobs; others were sent home to work. Essential businesses kept going. Despite protections, workers in sectors ranging from health care to transportation to food production and retail faced risk of infection, illness and even death. IWH researchers are looking at the impact of the pandemic on workers and workplaces, and what it means going forward.

What can work-related COVID-19 cases tell us about how to prepare for the next pandemic?

To what extent did workplace exposures account for the transmission of the COVID-19 virus during the first two years of the pandemic? A new study by IWH combined data sources to estimate work-related infection rates, using a method that took into account major shifts in where people worked. It found the role of work exposure changed from wave to wave, in a dynamic pattern not in keeping with the number of cases in the general population.

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.
