Their definition of long COVID is a condition in which a child or young person has symptoms (at least one of which is a physical symptom) that:
1.Have continued or developed after a diagnosis of COVID-19 (confirmed with one or more positive COVID tests)
2.Impact their physical, mental or social wellbeing
- Are interfering with some aspect of daily living (eg, school, work, home or relationships) and
- Persist for a minimum duration of 12 weeks after initial testing for COVID-19 (even if symptoms have waxed and waned over that period)
The definition, published in the journal of Archives of Disease in Childhood, closely complements the WHO definition for long COVID in adults.
