Findings
We identified widespread surface contamination (66 positive out of 73 samples) in occupied patient rooms (MPXV DNA Ct values 24·7-38·6), on healthcare worker personal protective equipment after use, and in doffing areas (Ct 26·3-34·3). Five out of fifteen air samples taken were positive. Significantly, three of four air samples collected during a bed linen change in one patient’s room were positive (Ct 32·7-35·8). Replication-competent virus was identified in two of four samples selected for viral isolation, including from air samples collected during the bed linen change.
