COVID-19 is generally mild in children1 and post-acute inflammatory conditions that are temporally associated with the virus are rare, but potentially severe. However, some children and adults experience persistent symptoms after COVID-19. 2 Long COVID has not been precisely defined, but one study reported symptoms approximately 60 days after the primary diagnosis.3 Although adult long COVID is increasingly being studied, the magnitude of persistent symptoms in children remains unclear.
