The aim was to review whether the scientific evidential basis has changed since April 2020. This document therefore builds on the evidence available in the literature and presents the main findings and recommendations for public health measures. The use of face masks by healthcare workers for the prevention of COVID-19 [coronavirus disease 2019] is out of the scope of this document and is covered in the latest update to the technical report 'Infection prevention and control and preparedness for COVID-19 in healthcare settings' [hyperlink], published on 9 February 2021."
