Incidencia de COVID-19 en trabajadores de salud. Actividad laboral y resguardo domiciliario

BACKGROUND: To determine the difference in the incidence of COVID-19 in health workers who remain in work activity and those who shelter at home. OBJECTIVE: determinar la diferencia de incidencia de COVID-19 en trabajadores de la salud que permanece en actividad laboral y los que se resguardan en domicilio. MATERIAL AND METHODS: Cohort study in health workers from March 2020 to January 2021. Two groups were integrated, the exposed group made up of workers who remained working in the health unit (n = 4650) and the non-exposed group, those who carried out home protection (n = 337). When the groups were integrated, none had a diagnosis of COVID-19, they were followed up for 11 months and when COVID-19 was diagnosed, it was done with a PCR test. Statistical analysis included incidence rate, confidence intervals, Chi square, relative risk, and confidence interval for relative risk. RESULTS: The incidence of COVID-19 in workers in home shelter was 39.8% (95% CI: 34.6-45.0) and in workers who remained in the medical unit 16.0% (95% CI: 14.9-17.1). The relative risk was 0.40 (95% CI: 0.34-0.47) for workers who remained working in the health unit. CONCLUSIONS: The incidence of COVID-19 was higher in health workers with home protection than in those who continued with normal activities in the medical unit.
