Retrospective cohort study shows children's role in SARS-CoV-2 transmission in households, suggesting importance of isolation measures.

This study highlights the importance of isolation measures to prevent household transmission of SARS-CoV-2 as well as counters common thought that children are less likely to transmit infection.
