张志江余雪杰傅学杰刘涛江宇杨燕Xiang Bing Bi毕冰此前的研究描述了成人和1岁以下婴儿Covid-19的临床特征。对于年龄在28天或28天以下的新生儿的特征、结局和宫内传播潜能知之甚少。通过系统搜索，截至3月13日，我们在中国新生儿中发现了4例感染病例。日龄30 h ~ 17 d。三是男性。2例新生儿发热，1例呼吸短促，1例咳嗽，1例无症状。为所有4名新生儿提供了支持性治疗。没有人需要重症监护或机械通气。没有任何严重的并发症。 Three newborn babies recovered by the end of this study and had been discharged with 16, 23, and 30 days of hospital stay. All 4 mothers were infected by SARS-CoV-2, 3 showing symptoms before and 1 after delivery. Cesarean section was used for all 4 mothers, 3 at level III hospitals and 1 at a level II hospital. Three newborn babies were separated from mothers right after being born and were not breastfed. In summary, newborn babies are susceptible to SARS-CoV-2 infection. The symptoms in newborn babies were milder and outcomes were less severe as compared to adults. Intrauterine vertical transmission is possible but direct evidence is still lacking. %U //www.qdcxjkg.com/content/erj/early/2020/04/01/13993003.00697-2020.full.pdf
