Non-neuropsychiatric Long COVID Symptoms in Children Visiting a Pediatric Infectious Disease Clinic After an Omicron Surge

Although much interest has emerged regarding post-COVID conditions, data on children and adolescents are limited. The prevalence of long COVID and common symptoms were analyzed in this case-control study of 274 children. Prolonged non-neuropsychiatric symptoms were more frequent in the case group (17.0% and 4.8%, P = 0.004). Abdominal pain (6.6%) was the most common long COVID symptom.
