A prospective study of 992 healthy children (median age 10.1 years) of healthcare workers from across the UK found that 68 (6.9%) tested positive for SARS-CoV-2 antibodies.1 Half of the children testing positive reported no symptoms, but for those that did the commonest were fever (21 of 68, 31%); gastrointestinal symptoms, including diarrhoea, vomiting, and abdominal cramps (13 of 68, 19%); and headache (12 of 68, 18%). Latest findings from the Covid-19 Symptom Study app,2 which was launched in late March to track people’s symptoms, also show that gastrointestinal symptoms occur frequently in children with positive swab tests.3
