ObjectiveTo study the clinical characteristics of imported coronavirus disease 2019 （COVID-19） cases in pregnancy.

MethodsTwo imported COVID-19 cases in pregnancy admitted to Shanghai public health clinical center from March 2020 to April 2020 were retrospectively analyzed.

ResultsThe two COVID-19 patients were in the second trimester of pregnancy， and were imported cases： case 1 came from the United States and was asymptomatic； case 2 came from Russia， and had fever， sore throat， cough and expectoration， and taste and smell loss. Laboratory testing on admission suggested that the albumin decreased in case 1. In case 2， lymphocyte count and percentage decreased， C-reactive protein and procalcitonin increased， albumin decreased， serum troponin increased， while the electrocardiogram was normal. Chest CT scans of the two cases were abnormal. They were administered with intensive care and nutritional support. Case 2 was treated with cefaclor tablets for 5 days. Case 1 and case 2 were hospitalized for 14 days and 12 days， respectively. They were discharged until twice nasopharyngeal swabs and fecal specimen tested negative for the novel coronavirus nucleic acid.

ConclusionThe treatment for the patients with normal type of COVID-19 in the second trimester of pregnancy is aimed to strengthen the monitoring during pregnancy， which needs nutritional and psychological intervention. However， follow-up of pregnancy outcome is warranted .
