The article addresses the critical issue of COVID-19 infection in children and the risk of reinfection over time. These data were gathered prior to the advent of the omicron variant of concern in England, but they provide valuable insights into the overall picture of COVID-19, which has been quite different in children versus adults. Notably, the risk of severe disease, including hospitalization and death, tends to increase with each decade of life. This study also indicates that the SARS-CoV-2 incidence rate in children is coherent with community trends. The authors reached the conclusion that the risk of SARS-CoV-2 reinfection was strongly related to community infection rates (particularly during the delta variant wave). They also observed that children had a lower risk of reinfection than adults, but reinfections were not associated with more severe disease or fatal outcomes.
