Des études récentes ont évalué les épidémies de COVID-19 et la surmortalité par secteurs professionnels. Les études sur l’infection par le SRAS-CoV-2 selon la profession et les facteurs liés à la profession font toujours défaut. Dans cette étude, nous estimons l’effet du travail en personne sur le risque d’infection par le SRAS-CoV-2 et décrivons la séroprévalence du SRAS-CoV-2 chez les adultes qui travaillent.
Abstract Objectives Recent studies have evaluated COVID-19 outbreaks and excess mortality by occupation sectors. Studies on SARS-CoV-2 infection across occupation and occupation-related factors remain lacking. In this study, we estimate the effect of in-person work on SARS-CoV-2 infection risk and describe SARS-CoV-2 seroprevalence among working adults. Methods We used Wave 1 data (May to June 2021) from CalScope, a population-based seroprevalence study in California. Occupation data were coded using the National Institute for Occupational Safety and Health Industry and Occupation Computerized Coding System. Dried blood spot specimens were tested for antibodies to establish evidence of prior infection. We estimated the causal effect of in-person work on SARS-CoV-2 infection risk using the g-formula and describe SARS-CoV-2 seroprevalence across occupation-related factors. Results Among 4335 working adults, 53% worked in person. In-person work was associated with increased risk of prior SARS-CoV-2 infection (risk difference: 0.03; [95% CI: 0.02?0.04]) compared with working remotely. Workers that reported job loss or who were without medical insurance had higher evidence of prior infection. Amongst in-person workers, evidence of prior infection was highest within farming, fishing, and forestry (55%; [95% CI: 26%?81%]); installation, maintenance, and repair (23%; [12%?39%]); building and grounds cleaning and maintenance (23%; [13%?36%]); food preparation and serving related (22% [13%?35%]); and healthcare support (22%; [13%?34%]) occupations. Workers who identified as Latino, reported a household income of <$25K, or who were without a bachelor's degree also had higher evidence of prior infection. Conclusions SARS-CoV-2 infection risk varies by occupation. Future vaccination strategies may consider prioritizing in-person workers. Consultez la page de l’article
