What is Known: • There are increasing reports on ‘long COVID’ in adults. • Only few studies have evaluated the long-term recovery from COVID-19 in children, and common for all studies is a small sample size (median number of children included 330), and most lack a control group.

What is New: • 0.8% of SARS-CoV-2 positive children reported symptoms lasting >4 weeks (‘long COVID’), when compared to a control group. • The most common ‘long COVID’ symptoms were fatigue, loss of smell and loss of taste, dizziness, muscle weakness, chest pain and respiratory problems. • These ‘long COVID’ symptoms cannot be assigned to psychological sequelae of social restrictions. • Symptoms such as concentration difficulties, headache, muscle- and joint pain as well as nausea are not ‘long COVID’ symptoms. • In most cases ‘long COVID’ symptoms resolve within 1-5 months.
