新型冠状病毒感染孕妇是否存在宫内垂直传播

新型冠状病毒肺炎疫情期间,母婴垂直传播问题引起了社会及围产医学界的广泛关注及热议,但目前尚无足够证据证明新型冠状病毒存在宫内垂直传播。本文重申了宫内垂直传播的相关概念,明确了相关研究的意义,并对未来在这一方面可能的研究方向及注意事项进行了阐述。同时呼吁科研工作者,坚持更加严谨求实的作风,进行科学的临床及基础研究,为提高对新型冠状病毒的认识提供科学的证据和信息。

Vertical transmission in COVID-19 pregnant women

During the COVID-19 epidemic,there have been many misconceptions concerning vertical transmission between the mother and fetus/baby,which has caused much discussion and controversy.However,there is no strong evidence to indicate that this novel coronavirus could be vertically transmitted from infected mothers to their fetuses/infants.Several easily confused concepts are clarified in this paper,including vertical transmission,intrauterine transmission,mother-to-infant transmission,intrapartum or postpartum transmission.Well-designed protocols and a disciplined research team are essential for both basic and clinical research,in order to contribute to obtaining more scientific evidence for better understanding of the characteristics of this novel coronavirus.Proper handling and disposal of the body fluids and tissue are critical for safety.We highlight the significant value of relevant research,and suggest future research directions,such as investigating the impact of COVID-19 in different trimesters.Furthermore,China has the most experience of treating pregnant women exposed to the COVID-19 virus,and it would be a great service to the rest of the world,for all centers in China to collaborate to report this collective experience.
