RESUMEN
OBJECTIVES: The aims of the studies are to describe COVID-19 outbreaks in the workplaces of the Monteregie Region, Quebec, Canada, and to evaluate potential risk factors for identifying at least one COVID-19 outbreak in these workplaces. METHODS: An ecological retrospective cohort study was conducted using deidentified databases of COVID-19 outbreaks that occurred in workplaces from February 27, 2020, to June 30, 2021. RESULTS: Among 30,489 workplaces studied, 897 workplaces with at least one COVID-19 outbreak were identified. These outbreaks were associated with a sizeable number of workers in the workplace (adjusted odds ratio [aOR] = 6.78; 95% CI: 5.43-8.47), the presence of temporary foreign workers (aOR = 2.26; 95% CI: 1.53-3.33), contacts with clients (aOR = 1.93; 95% CI: 1.68-2.21), and being localized in the Montreal Metropolitan Area (aOR = 1.26; 95% CI: 1.09-1.45). CONCLUSIONS: These results enable the identification of potential risk factors for COVID-19 outbreaks in workplaces, with the aim of targeting workplaces where infection control and prevention measures might be enhanced or adapted to improve workers' health.

Two patients with no exposure to gardening compost had related Legionella longbeachae infections in Quebec, Canada. Epidemiologic investigation and laboratory results from patient and soil samples identified the patients' workplace, a metal recycling plant, as the likely source of infection, indicating a need to suspect occupational exposure for L. longbeachae infections.
