Roles of children, isolation measures and socioeconomic status in SARS-CoV-2 household transmission: a retrospective cohort study in a southern US city

Key Points

Child index cases lead to household secondary sars-cov-2 infections at rates similar to adults, emphasizing their role in transmission.
Sharing rooms correlates with a notable increase in household infection incidence, highlighting risk factors in setting.
Retrospective cohort study investigated transmission dynamics within households, focusing on the influence of children's roles.
This analysis indicates the necessity for effective isolation measures to curb household spread of sars-cov-2, especially among children.

Abstract

Child index cases appeared as likely to result in household secondary SARS-CoV-2 infections as adult index cases, while sharing rooms was associated with higher incidence of infection. This study highlights the importance of isolation measures to prevent household transmission of SARS-CoV-2 as well as counters common thought that children are less likely to transmit infection.
