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 Copyright © 2020 by the Chinese Medical Association
