Results
There were 109 household members (66 adults and 43 children). The median attack rate per cluster was 60% (range: 33.4%100%). An adult member with COVID19 was the first case in 21 (91.3%) clusters. Transmission of infection occurred from an adult to a child in 19 clusters and/or from an adult to another adult in 12 clusters. There was no evidence of child to adult or child to child transmission. In total 68 household members (62.4%) tested positive. Children were more likely to have an asymptomatic SARSCoV2 infection compared to adults (40% versus 10.5%, pvalue=0.021). In contrast, adults were more likely to develop a severe clinical course compared to children (8.8% versus 0%, pvalue=0.021). In addition, infected children were significantly more likely to have a low viral load while adults were more likely to have a moderate viral load (40.7% and 18.5% versus 13.8% and 51.7%, respectively; pvalue=0.016).
Conclusions
While children become infected by SARSCoV2, they do not appear to transmit infection to others. Furthermore, children more frequently have an asymptomatic or mild course compared to adults. Further studies are needed to elucidate the role of viral load on these findings.
