[COVID-19 outbreak investigation in a geriatric palliative hospital].

Background: During the second COVID-19 wave, a large COVID-19 outbreak happened at a 90-bed geriatric palliative care hospital in December 2020, whereby 32 % of the healthcare personnel (HCP) and 29 patients became infected within 23 days and 13 patients died. The bed occupancy rate dropped to 20 %. Drastically enhanced hygiene measures directly after outbreak detection could stop further nosocomial infections among patients but were less effective among HCP.
