SARS-CoV-2 attack rate in reception and accommodation centres for asylum seekers during the first wave: Systematic review of outbreak media reports in Germany

Abstract

Mass quarantine is associated with higher attack rates, and appears to be a counter-productive containment measure in overcrowded camps, but further research with individual-level data is required to rule out residual confounding. Despite available vaccines, reception centres and refugee camps should follow the available guidelines on COVID-19 response and refrain from mass quarantine if physical distancing cannot be guaranteed.
