(1/5) Study of #SARSCoV2 antibody prevalence in children from Bavaria, Germany, showing infections in children were 6 times higher than PCR tests suggested, and that young & older children were equally likely to be infected. Almost half were asymptomatic.

(2/5) The children in this study were recruited from a representative, population-based diabetes screening study of 11,884 children.

Overall, 0.87% tested positive between April and July.

Almost half (47%) had had an asymptomatic infection.

(3/5) There was no statistically significant difference in antibody prevalence between children aged 0-6 years (0.84%) and those aged 7-18 years (0.98%).

In contrast, the results of official PCR tests had suggested young children were much less likely to be infected.

(4/5) This study therefore has two key findings.

First, cases in children are frequently undetected. This is also true for adults.

The second, more important finding is that cases in young children are disproportionately missed.

(5/5) The study therefore suggests that both young and older children are equally likely to be infected, and that the high prevalence of asymptomatic infection in children is causing cases in younger children to go undetected.
