Results are presented in median [interquartile range] for continuous variables and in the counts (percentages) for categorical variables
Gastrointestinal symptoms included nausea, vomiting, diarrhoea, and abdominal pain
Hospital-associated cases included HCW-cases and patient-cases. Among the patient-cases, there were five patients with community-onset of COVID-19 and four patients with hospital-onset of COVID-19. Community-cases were those that were community-associated (i.e., household and nursing home)
*A statistically significant difference was detected for age (p < 0.05), sore throat (p = 0.02), and previous comorbidities (p < 0.05)
