Abstract

Abstract Objective: to describe the COVID-19 clinical outcomes profile from mining workers and the cases dynamic within the mining units and their respective municipalities. Methods: a cohort and ecological study using workers clinical-epidemiological, sociodemographic, and occupational secondary data of a multinational mining company, and of COVID-19 cases from five municipalities where the mining units were located, in Brazil, between March 2020 to April 2021. We calculated the cases cumulative incidence and the 7-day moving average (MA), and compared at the mining unit and respective municipality. Results: the study included 17,523 workers, 88.4% male, and 22.6% had at least one positive result for COVID-19. The workers most tested, with positive results, placed in quarantine, and with symptoms were female, middle-aged, living and working in Rio de Janeiro state, directly hired by the mining company, in shift-work, and in high-risk occupations. All mining units presented a cumulative incidence higher than their respective municipalities. Three municipalities showed peaks of COVID-19 with MA cases coinciding with an increase in cases among mining workers. Conclusion: approximately one-fifth of workers were diagnosed with COVID-19. The mining units had a similar temporal distribution of COVID-19 cases to the municipalities where they were located.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
