The authors describe a nosocomial outbreak of SARS-CoV-2 infection in the paediatric dialysis unit of a hospital in Germany. 48 cases were involved in the outbreak.

Therefore person-to-person transmission was responsible for a hospital outbreak of COVID-19 between healthcare workers and patients in the paediatric dialysis unit.
