Emerg Infect Dis. 2021 Jan;27(1):317-319. doi: 10.3201/eid2701.203849. Epub 2020 Oct 19.


We report a cluster of surprisingly high spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) associated with a single nursery in Poland. Our findings contrast with the presumed negligible role of children in driving the SARS-CoV-2 pandemic. Children 1-2 years of age might be effective SARS-CoV-2 spreaders.
