JAMA Pediatr:新冠肺炎家庭传播案例中 儿童年龄越小成为“零号”病人的可能性越大

2021-08-24 MedSci原创 MedSci原创

与年龄较大的儿童相比,年龄较小的儿童成为家庭SARS-CoV-2传播者的几率较高,特别是0至3岁儿童的传播风险最高

由于早期病例较少,儿童群体在新冠肺炎传播链中的作用尚未得到充分研究。一般认为,与成人相比,儿童成为新冠肺炎传播者的比例较小。在2020年秋季放松了公共卫生措施和学校重新开学后,儿童Covid-19病例的数量有所增加,为这一研究的进行提供了可能。近日研究人员考察了儿童年龄与新冠肺炎家庭传播风险之间的关系。

本次基于人群的队列研究于2020年6月1日至12月31日在加拿大安大略省进行,参与者为18岁以下,经实验室确诊的SARS-CoV-2感染病例。按儿童年龄分为0-3岁、4-8岁、9-13岁和14-17岁组。研究的主要终点为家庭传播,定义为儿童病例确诊后1-14天继发病例。

总计6280个新冠肺炎儿童家庭参与研究,1717个家庭(27.3%)存在二次传播。儿童病例平均年龄为10.7岁,女童2863人(45.6%)。与14至17岁的儿童相比,0至3岁的儿童向家庭接触者传播SARS-CoV-2的几率最高(风险比为1.43),其次为4-8岁儿童(1.40)和9-13岁儿童(1.13)。

研究表明,与年龄较大的儿童相比,年龄较小的儿童成为家庭SARS-CoV-2传播者的几率较高,特别是0至3岁儿童的传播风险最高
