COVID-19 surge phases: an alert-warning tool

The COVID-19 surge phases: an alert-warning tool is available here.

COVID-19 surge phases is an alert-warning tool has been developed during the Covid-19 pandemic in the context of Pan European Response to the ImpactS of COvid-19 and future Pandemics and Epidemics (PERISCOPE) European Union’s Horizon 2020 research and innovation program.

The effective monitoring of the pandemic emergency and, specifically, the early detection of surge phases are crucial to define proper health policies. We propose a statistical testing approach to identify the acceleration in contagion growth that potentially marks the start of new waves, based on the study of the reproduction rate dynamics. The proposed method can be considered as a supplementary early warning system that can assist policymakers in the attempt to anticipate and tailor countermeasures. It can also be used as an ex-post tool to date-stamp surge phases and evaluate the impact of the implemented strategies on their timing. The effectiveness of our approach is exemplified on ten countries' contagion data, reaching robust and insightful results in assessing the timing and severity of COVID-19 surge phases.

Below the considered countries: Austria, Czechia, Denmark, Germany, France, Italy, Portugal, Spain, Sweden, United Kingdom

The methodology used for the wave detection fitting process is currently under review and it is available as working paper here.
