The newly identified 2019 novel coronavirus disease (COVID-19) is spreading nationwide. Previous studies mainly focus on non-pregnant population with COVID-19. The purpose of this study is to investigate and analysis the clinical features, imaging findings, related laboratory indicators and outcomes of maternal-fetal for cases of of 55 pregnant women who had been initials dignosed with suspected infection COVID-19 at Maternal and Child Health Hospital of Hubei Province, Tongji Medical College, Huazhong University of Science and Technology, a tertiarycare teaching hospital in Hubei province, Wuhan, China from January 23 to March 5, 2020 . Among the 55 cases, 13 patients were assigned into the confirmed COVID-19 group and the other 42 patients were assigned into the control group for being ruled out COVID-19 pneumonia. All the 13 confirmed pregnant women were diagnosed with asymptomatic and mild COVID-19, and no one of the patients developed severe COVID-19 or died. For the parturient women with asymptomatic and mild COVID-19, the clinical symptoms and laboratory indicators are not obvious. Pulmonary CT image of those manifestations is not the specific clinical features of COVID-19 pneumonia. The count of Lymphocyte was lower in the confirmed COVID-19 cases, but there was no change in the normal cases. In Wuhan where the incidence of COVID-19 is high, pulmonary CT screening on admission may be necessary to reduce the transmission of COVID-19 during the outbreak period. Pulmonary CT scan plus blood routine examination of WBC, Neutrophil and Lymphocyte are more suitable for finding pregnancy women with asymptomatic or mild COVID-19 infection once pregnant women are in labor and have no time to confirm COVID-19, and thus protecting normal pregnancy women and medical staffs.
