Using data from 4678 children participating in VirusWatch, a household cohort study, we estimated the prevalence of persistent symptoms lasting ≥4 weeks as 1.7%, and 4.6% in children with a history of SARS-CoV-2 infection. Persistent symptom prevalence was higher in girls, teenagers and children with long-term conditions.
