Coronavirus disease 2019 (COVID-19) has spread rapidly across the world. Given the sharply increased infection rate, the number of pregnant women and children with COVID-19 is correspondingly on the rise. SARS-CoV-2 infection is transmitted through droplets; though hypothesized, other transmission routes have not been confirmed. As of now, it remains unclear whether and how SARS-CoV-2 can possibly be transmitted from the mother to the fetus.
This study examines the medical records of 30 neonates born to women with COVID-19, the objective being to provide documented information on maternal-child transmission and infant outcomes.
Out of the 30 newborns, 28 had negative PCR test results for SARS-CoV-2; among their mothers, fifteen had fever, nine had cough and twenty had delivered by cesarean section. The median birth term was 37wk2dy, and twenty of the neonates were male. Most of them were asymptomatic, except for the three who presented with shortness of breath. Two of them were intubated and both died, the first because of severe sepsis and the second due to severe hyaline membrane disease. As regards the two infected neonates, the first represents a probable case of congenital SARS-CoV-2 infection, which appears unlikely in the second case. The outcome for both of them was good, without any complications.
Maternal-fetal transmission of the SARS- CoV-2 virus was not detected in the majority of the reported cases, although two of 30 neonates had positive qRT-PCR test results. Our study supports the hypothesis that though it seldom actually occurs, in utero SARS-CoV-2 vertical transmission is possible.
新型冠状病毒病 2019(COVID-19)已在全球迅速蔓延。鉴于感染率急剧上升,COVID-19 的孕妇和儿童数量也相应增加。SARS-CoV-2 通过飞沫传播;虽然有假设,但其他传播途径尚未得到证实。截至目前,尚不清楚 SARS-CoV-2 是否以及如何可能从母亲传播到胎儿。
本研究检查了 30 名 COVID-19 母亲所生新生儿的病历,目的是提供母婴传播和婴儿结局的有文件记录的信息。
在 30 名新生儿中,28 名新生儿 SARS-CoV-2 的 PCR 检测结果为阴性;在他们的母亲中,15 名有发热,9 名有咳嗽,20 名通过剖宫产分娩。中位出生期为 37wk2dy,20 名新生儿为男性。他们大多无症状,只有 3 名有呼吸急促。其中 2 名需要插管,2 名都死亡,第一个是因为严重败血症,第二个是因为严重透明膜病。关于这两个感染的新生儿,第一个是 SARS-CoV-2 先天性感染的可能病例,第二个不太可能。他们的结果都很好,没有任何并发症。
在报告的大多数病例中,未检测到 SARS-CoV-2 病毒的母婴传播,但在 30 名新生儿中有 2 名 qRT-PCR 检测结果为阳性。我们的研究支持这样的假设,即尽管实际上很少发生,但 SARS-CoV-2 垂直传播在子宫内是可能的。
