Statement by the Commission for Infection Prevention and Hygiene in Healthcare and Nursing (KRINKO) on the indication-appropriate use of mouth-nose protection (MNS) in healthcare

Three types of MNS which are distinguished in the DIN EN 14683 are presented. Examples for typical indications for medical face masks for healthcare workers, patients and external persons are summarized. Examples of situations in which the use of medical face masks is not indicated are also shown. By reducing the use of medical face masks through strictly indication-based use, clarification of the areas of application for the three types of MNS, and differentiated and indication-based use of FFP2 masks, a responsible and sustainable use of medical face masks can be implemented in accordance with IPC measures.
