This series draws on the COVID-19 Health System Response Monitor (HSRM) which collects and organizes up-to-date information on how countries are responding to the COVID-19 crisis across the whole European Region. It focuses priMarsily on the responses of health systems, but also captures wider public health initiatives and has been able to deliver cross country analysis on some of the most pressing challenges. The HSRM has been delivered by the European Observatory on Health Systems and Policies as a joint undertaking with and for the WHO Regional Office for Europe and the European Commission.
