Introduction
Since the outbreak of the novel coronavirus pneumonia (COVID-19) in Wuhan in December 2019[1], the epidemic has spread rapidly throughout the world, especially in Europe and North America. There have been almost 90 million cases worldwide[2]. It was declared to be a pandemic and one of the most important public heathy issues worldwide. Till now, there are many studies on the epidemiology, clinical characteristics and treatment of novel coronavirus pneumonia [3-4], and the novel virus that caused the pneumonia was named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)[5] . Studies about pregnant women with COVID-19 were limited, and vaginal delivery in such patients was not reported so far. We admitted 30 pregnant women in Union Hospital (Wuhan, China) between 31 January to 20 April 2020,eight of them delivered vaginally. This study retrospectively analyzed the clinical features and maternal and fetal outcomes of these 8 patients,with the aim of discussing the indications of vaginal delivery and whether vaginal delivery increases the probability of mother to child transmission of SARS-COV-2.
