Odds ratio of higher symptom severity in children with SARS-CoV-2 infection

	N = 381	N = 1271	N = 97	OR of moderate symptoms (95% CI)
Age category	Asymptomatic – no (%)	Mild – no (%)	Moderate – no (%)
<6 months	3 (0.8)	16 (1.3)	0 (0.0)	N/A
6 months–3 years	45 (12.0)	176 (13.7)	11 (13.6)	1.05 (0.56–1.97)
4–7 years	116 (31.0)	214 (16.6)	12 (14.8)	0.91 (0.52–1.59)
8–13 years	156 (41.7)	529 (41.1)	31 (38.3)	0.82 (0.52–1.28)

Sex – no (%)
Female	173 (46.3)	613 (47.6)	42 (51.9)	1.12 (0.73–1.72)

No children were severely or critically ill. Data was missing for 7 children.

OR: Odds ratios calculated by binary logistic regression modelling where the reference value was moderate disease. Models were adjusted by source of infection.

CI indicates confidence interval.
