Children account for a small proportion of diagnoses of SARS-CoV-2 infection and do not exhibit greater viral loads than adults

Abstract : Previous reports have suggested that children are less affected than adults by SARS-CoV-2. We analyzed SARS-CoV-2 diagnoses between February 27, 2020, and March 14, 2020, and mortality among positive patients in Marseille university hospitals. Of 4050 tested individuals, 228 were positive. Deaths occurred in 2/99 documented cases (both > 85 year-old). Children were majorly asymptomatic. Incidence increased by 7.4-fold between 1-5 and 45-65 years then decreased. It was significantly lower among 0-1 year- (0%) and 1-5 (1.1%) and 5-10 (3.6%)-year-old children than among subjects > 18 years (6.5%). Viral loads did not differ between children and adults. Children may not contribute significantly to virus circulation.
