SARS-CoV-2 outbreak in medical employees in a large urologic department: Spread, containment and outcome.

Background The SARS-CoV-2 pandemic presents an unprecedented challenge to health care systems worldwide. Data on SARS-CoV-2 transmission in a hospital is rare and outbreaks among health care professionals are complex to control. Material and Methods Over the course of 6 consecutive weeks we recorded data on an exponential outbreak of SARS-CoV-2 within our department. We reconstructed the assumed route of the spread of infection, and the employees’ acute and late symptoms. Increasing preventive measures (mandatory face masks, intense training in hygiene, physical distancing whenever possible, and termination of visits from outside the hospital) were implemented. Results Within 6 weeks, 13 employees were tested positive for SARS-CoV-2. All individuals had a moderate course, not resulting in hospitalization. The majority of infections was discovered after testing contacts of known cases, prior to their onset of symptoms and was predominantly related to removal of face masks during breaks. Increasing preventive measures resulted in a decline and finally containment of transmission rates amongst the staff, confirmed by mass testing at week 6, with no further SARS-CoV-2 infection. Three individuals, all in their late 40s or older, have lasting or newly onset neurological symptoms 8 months after their infection. Conclusions Outbreaks of SARS-CoV-2 are particularly difficult to contain in a medical setting, where employees work in close physical proximity. Adherence to preventive measures, particularly face masks, seem to be effective.
