Abstract
Objective. Study aimed to estimate the speed of SARS-CoV2 infection according to healthcare workers’ jobs at hospital.
Methodology. A prospective cohort study was conducted. The ANOVA procedure was used to evaluate the differences among three different hospital job types and the Kaplan-Meier procedure to estimate the median speed of infection.
Results. There was difference between the frequency of Sars-CoV-2 infection between women’s cumulative incidence rate of 27.7% compared to that of men at 22.3%, Chi2 = 4.24 DF = 1, p = 0.04. The average age of the three work groups (Clinicians, administrative staff, and maintenance workers) showed also difference (F Snedecor = 19.2 DF = 2, p = 0.000). There was no statistically significant difference regarding the speed of SARS-CoV-2 infection according to sex (Log Rank = 0.02 DF = 1, p = 0.89). In addition, there was no difference regarding the speed of infection according to the hospital job performed (Log Rank = 3.74 DF = 2, p = 0.15).
Conclusions. Infection tends to be more frequent among women. There is no difference in infection speed among sexes, nor among jobs performed. Infection prevention measures must be reinforced, to avoid contagion and prevent its spread within the hospital.
