Social distancing is an action taken to minimise contact with other individuals; social distancing measures comprise one category of non-pharmaceutical countermeasures (NPCs)1 aimed at reducing disease transmission and thereby also reducing pressure on health services. This document builds upon existing ECDC documents, including guidelines for the use of non-pharmaceutical measures to delay and mitigate the impact of 2019-nCoV, a rapid risk assessment: outbreak of novel coronavirus disease – 5th update, a technical report on the use of evidence in decision-making during public health emergencies, and a guidance document on community engagement for public health events caused by communicable disease threats in the EU/EEA.
