*3.1. Sample Characteristics*

We collected 382 surveys. The participants' mean age was 42.97 (95% CI: 41.94–44.00) years; 82.2% (*n* = 314) were female and 53.7% (*n* = 205) considered that their health status was good; 63.4% (*n* = 242) had children, and 21.7% (*n* = 83) looked after elderly people. Most of the participants in our sample were registered nurses (56.8%; *n* = 217); 54.7% (*n* = 209) of the sample had more than 15 years of experience and 52.4% (*n* = 209) had temporary contracts. Most of the participants belonged to the public health system (96.9%; *n* = 370), specifically from HD2 (74.6%; *n* = 285), they worked in a hospital (74.6%; *n* = 285), and 84.8% (*n* = 324) had been in contact with COVID-19 patients. Only 15.7% (*n* = 60) stated that they had had a diagnosis test and 18.3% (*n* = 70) had been isolated. The prevalence of COVID-19 cases in the study sample was 7.6% (*n* = 29). Table 1 shows the analysis of the socio-demographic, occupational, and COVID-19 exposure-related variables.
