# A public health perspective of SARS-CoV-2 evolution and surveillance strategies in Germany from 2020 to 2023

## TL;DR

The paper reviews how SARS-CoV-2 evolved in Germany from 2020 to 2023 and the importance of genomic surveillance for public health and pandemic preparedness.

## Contribution

The paper provides a comprehensive public health perspective on SARS-CoV-2 evolution and surveillance strategies in Germany.

## Key findings

- Nationwide genome collection helped track SARS-CoV-2 lineage frequencies and mutations.
- Continuous virological surveillance is essential for adapting public health strategies.
- The RKI's interdisciplinary approach supported pandemic response and preparedness.

## Abstract

This review summarizes key virological parameters of SARS-CoV-2, the clinical spectrum of COVID-19, antiviral options, resistance, and the evolution of SARS-CoV-2 during the first four years of the pandemic. It draws on evidence that has been continuously updated throughout the pandemic by the interdisciplinary working group ‘SARS-CoV-2 Diagnostics and Evolution’ at Robert Koch Institute (RKI), Germany’s national public health institute. We describe basic SARS-CoV-2 characteristics and highlight notable virus variants from 2020 to mid-2023. During this period, the nationwide collection of SARS-CoV-2 genomes provided a substantial resource for monitoring viral lineage frequencies and mutations. We summarize this dataset to underscore the importance of virological surveillance in the context of public health and pandemic preparedness.

Oh, Hölzer et al., discuss the multidisciplinary approach used for monitoring the genomic and virological evolution of SARS-CoV-2 during the COVID-19 pandemic and its implications on public health in Germany. They emphasize the need for continuous surveillance and adaptation of public health strategies to address evolving viral threats.
