CAMBRIDGE – When Addenbrooke’s Hospital upgraded its face masks for staff working on Covid-19 wards to FFP3 (filtering face piece) respirators, it saw a dramatic fall – up to 100% – in hospital-acquired SARS-CoV-2 infections among staff.
The findings are reported by a team at the University of Cambridge and Cambridge University Hospitals (CUH) NHS Foundation Trust. The research has not yet been peer-reviewed, but is being released early because of the urgent need to share information relating to the pandemic.
