Use of FFP3 respirators on coronavirus units at Addenbrooke’s ‘may have cut ward-based infection to zero’
An NHS hospital that upgraded the type of face masks used by staff on Covid-19 wards recorded a dramatic fall of up to 100% in hospital-acquired coronavirus infections among those workers, research has indicated.
Addenbrooke’s hospital in Cambridge upgraded the masks from fluid resistant surgical masks (FRSMs) to filtering face piece 3 (FFP3) respirators, with the change made in late December in response to its own staff testing data.
