Early extension of risk areas at the COVID-19 rapid response infrastructure, University Hospital Cologne, Germany, February 2020
CRRI: COVID-19 rapid response infrastructure; RKI: Robert Koch Institute; SARS-CoV-2: severe acute respiratory syndrome coronavirus 2.
Bars show changes in risk areas in Austria (upper bar) and Italy (lower bar) as defined by the German national public health institute (Robert Koch Institute (RKI)) over time. The respective RKI areas at risk are depicted below by bars which change colour when new areas were added (no area at risk was defined for Austria before 13 March 2020). Orange dots indicate the number of patients (one dot per patient) on each respective day that tested positive for SARS-CoV-2 due to the extended risk areas used for testing at the CRRI.
