Occupational exposures and mitigation strategies among homeless shelter workers at risk of COVID-19

ObjectiveTo describe the work environment and COVID-19 mitigation measures for homeless shelter workers and to assess occupational risk factors for COVID-19 infection MethodsBetween June 9 and August 10, 2020, we conducted a self-administered, web-based survey among homeless shelter workers in Washington, Massachusetts, Utah, Maryland, and Georgia, in shelters where at least 1 staff person had tested positive for SARS-CoV-2. We calculated frequencies for demographics, work environment, personal protective equipment use, and SARS-CoV-2 testing history. We used generalized linear models with a binary outcome (COVID-19 positivity) and a log link, clustered by shelter network, to produce unadjusted prevalence ratios (PR) for demographics, work environment, and mitigation measures. ResultsOf the 106 respondents, 43.4% reported frequent close contact with clients and 85.8% reported wearing a mask most or all of the time; 75% reported being worried about being infected with SARS-CoV-2 at work; 15% reported testing positive for SARS-CoV-2. Of those who reported testing positive for SARS-CoV-2, 80% (12/15) believed they were infected at work. Frequent close contact with clients was significantly associated with testing positive for SARS-CoV-2 (PR 3.97, 95% CI 1.06, 14.93). ConclusionsHomeless shelter workers may be at higher risk of being infected with SARS-CoV-2 during the course of their work.
