The SARS-CoV-2 coronavirus produces the same clinical symptoms in pregnant women as it does other infected people, and there is currently no evidence for vertical transmission.

The recent outbreak of COVID-19 pneumonia, caused by SARS-CoV-2, has been declared a global public-health emergency by the World Health Organization. SARS-CoV-2 is highly infectious, and the disease can lead to death; however, it is unknown whether pregnant women have specific support needs after infection and, in particular, if there is a risk of vertical transmission to unborn children.

Chen et al. studied nine pregnant women with lab-confirmed COVI-19 who were admitted to the Zhongnan Hospital of Wuhan University. They found that their clinical symptoms were similar to those of non-pregnant adults and that there was no indication of vertical transmission to children, although the findings need to be confirmed in a larger study.
