Different spreading dynamics throughout Germany during the second wave of the COVID-19 pandemic: a time series study based on national surveillance data.

ABSTRACT:

Background

The second wave of the COVID-19 pandemic led to substantial differences in incidence rates across Germany.

Methods

Assumption-free k-nearest neighbour clustering from the principal component analysis of weekly incidence rates of German counties groups similar spreading behaviour. Different spreading dynamics was analysed by the derivative plots of the temporal evolution of tuples [x(t),x'(t)] of weekly incidence rates and their derivatives. The effectiveness of the different shutdown measures in Germany during the second wave is assessed by the difference of weekly incidences before and after the respective time periods.

Findings

The implementation of non-pharmaceutical interventions of different extents resulted in four distinct time periods of complex, sp
