ABSTRACT
OBJECTIVE: To determine the probability of hospitalization for chronic degenerative disease in patients with COVID-19. MATERIALS AND METHODS: A retrospective cohort in patients with COVID-19, confirmed by RT-PCR. Two study groups were integrated, the exposed group made up of 3 subgroups, exclusively diabetes mellitus, exclusively arterial hypertension and exclusively obesity;the unexposed group was the one in which any chronic comorbidity was ruled out. Relative risk, multiple logistic regression and probability calculation of the event (hospitalization) were used. RESULT(S): The relative risk for hospitalization in diabetes was of 3.59 (95%CI;2.44-5.29), 3.20 (95%CI;2.10-4.87) in hypertension and 2.56 (95%CI;1.72-3.81) in obesity. The multiple regression equation was y = -1358 + 2388 (diabetes mellitus) + 2005 (systemic arterial hypertension) + 1458 (obesity). The probability of hospitalization when there was no chronic disease was of 20.6%, when there was a chronic disease the probability fluctuated between 52.5% and 73.5%, when there were two chronic diseases it varied from 89.1% to 95.4%, and when there were three diseases the probability of hospitalization was of 98.9%. CONCLUSION(S): In the context of the probability of hospitalization when there is a chronic degenerative disease or it is absent, the research shows the difference in these two scenarios, as revealed by the more than 70 percentage points identified in the extreme scenarios, a condition that, led to the clinical field, reaffirms the presence of chronic degenerative disease as a risk factor for hospitalization.Copyright © 2023 Comunicaciones Cientificas Mexicanas S.A. de C.V..

ABSTRACT
Background: The COVID-19 pandemic has had repercussions in the social, economic, psychological and health spheres, for which risk and exposure groups have been identified. Health workers are distinguished from the rest of the population by constant contact with patients carrying the SARS-CoV-2 virus. Objetive: To determine the difference in the incidence of COVID-19 in health workers who remain in work activity and those who shelter at home. 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. Conclusion: 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.
