The impact of Covid-19 on the health of physicians, nurses and other healthcare workers: an interprovincial cohort study
The objectives of this study are:
1. To assess the impact of working through the Covid-19 pandemic on health care workers (HCW);
2. To identify remediable workplace practices associated with infection in HCW and interventions helpful in managing the mental health impact of the pandemic; and
3. Post-vaccine, to monitor changes in IgG antibody concentration over time.
