Knowledge of transmission dynamics of severe acute respiratory syndrome coronavirus 2 from adults to children in household settings is limited. We found an attack rate among 213 children in 137 households to be 6.1% in households with confirmed adult 2019 novel coronavirus disease index case(s). Transmission from adult to child occurred in only 5.2% of households. Young children <5 years old were at lowest risk of infection (1.3%). Children were most likely to be infected if the household index case was the mother.
关于成人向儿童传播严重急性呼吸综合征冠状病毒 2 的传播动力学知识在家庭环境中是有限的。我们发现，在 137 户家庭的 213 名儿童中，有确诊成人 2019 年新型冠状病毒病病例的家庭中，儿童的发病率为 6.1%。从成人到儿童的传播仅发生在 5.2%的家庭中。年龄较小的儿童（<5 岁）感染风险最低（1.3%）。如果家庭的指数病例是母亲，儿童最有可能被感染。
