A population-based prospective cohort study of residents of long-term care homes, people living in shelters, and members of the general population in Toronto, Canada found that residents of long-term care homes were 2.4 times more likely to test positive for SARS-CoV-2 than the general population and those who received a diagnosis of COVID-19 were 1.4 times more likely to die. The study found that cumulatively, the diagnosed cases per capita was 64-fold higher among long-term care home residents and 19-fold higher among shelter residents, compared with the rest of the population.
