A meta-analysis of the role of children in SARS-CoV-2 household transmission identified 213 transmission clusters from 12 countries, and found that only 8 clusters (3.8%) had a pediatric index case. Asymptomatic index cases were associated with a lower secondary attack rate in contacts than symptomatic index cases (RR 0.17). The secondary attack rate was also lower among pediatric than adult household contacts (RR, 0.62).
