In conclusion, a policy of systematic screening with a specific questionnaire is a manageable, inexpensive, and effective tool in obstetric care, at least in areas where the incidence of SARS-Cov-2 infection is not devastating. However, it is not infallible. If swabs can be processed within a matter of hours, a universal swab policy is preferred. EF and BT designed the study. GL, MPF and MR collected the data. ES wrote the first draft. All the authors revised the manuscript. Figure 1 . The patient experienced rapid aggravation of the disease. Emergency cesarean delivery was performed at the bedside, but the neonate died within two hours of birth (Fig. 2 ). Although the patient had no history of chronic disease, the severity of COVID-19 increased rapidly-from dyspnea to acute respiratory distress syndrome and septic shock within 12 hours. The patient's condition worsened, with persistent decreases in white blood cell and lymphocyte counts. Inflammation indicators of C-reactive protein, procalcitonin, and interleukin 6 all increased significantly, whereas peripheral oxygen saturation level decreased progressively. Given these circumstances, white blood cell and lymphocyte counts of COVID-19 patients should be monitored Universal screening for SARS-CoV-2 in women admitted for delivery Critical care utilization for the COVID-19 outbreak in Lombardy ISUOG Interim Guidance on 2019 novel coronavirus infection during pregnancy and puerperium: information for healthcare professionals The authors have no conflicts of interest.
