A two-ward acute care hospital outbreak of SARS-CoV-2 delta variant including a point-source outbreak associated with the use of a mobile vital signs cart and sub-optimal doffing of personal protective equipment.

Monitoring of PPE compliance based on covert observations There was a highly significant association with sub-optimal adherence to doffing, hand hygiene and order of doffing on Ward 2 (55% and 64% of the time, respectively) compared to four adult-designated COVID-19 wards (78% and 89%, respectively; P = 0.007; N = 54 HCW-unaware audits) in the three-month period prior to the outbreak.
