Background: Compared with Severe Acute Respiratory Syndrome MESHD(SARS) and Middle East Respiratory Syndrome MESHD(MESR), Corona Virus Disease MESHD 2019(COVID-19) spread more rapidly and widely. The population was generally susceptible. However, reports on pregnant women infected with SARS-CoV-2 were very limited. By sharing the clinical characteristics, treatments and outcomes of 18 patients with COVID-19 during late pregnancy, we hoped to provide some references for obstetric treatment and management.Methods: A total of 18 patients with COVID-19 treated in Renmin Hospital of Wuhan University were collected. The epidemiological characteristics, clinical manifestations, laboratory tests, chest CT and pregnancy outcomes were performed for analysis.Results: 1. 18 cases of late pregnancy infected with SARS-CoV-2 pneumonia MESHD pneumonia HP were delivered at 35 + 5 weeks to 41 weeks. According to the clinical classification of COVID-19, 1 case was mild type, 16 cases were ordinary type, and 1 case was severe type. 2. According to Imaging examinations: 15 (83%) cases showed unilateral or bilateral pneumonia MESHD pneumonia HP, 2 (11%) cases had pulmonary infection MESHD with pleural effusion MESHD pleural effusion HP, and 1 (6%) case had no abnormal imaging changes. 8 (44%) cases were positive and 10 (56%) cases were negative for nasopharyngeal-swab tests of SARS-CoV-2. 3. Among the 18 newborns, there were 3 (17%) premature infants, 1 (6%) case of mild asphyxia MESHD, 5 (28%) cases of bacterial pneumonia MESHD pneumonia HP, 1 (6%) case of gastrointestinal bleeding, 1 (6%) case of necrotizing enteritis MESHD, 2 (11%) cases of hyperbilirubinemia MESHD hyperbilirubinemia HP and 1 (6%) case of diarrhea MESHD diarrhea HP. All the newborns were negative for the first throat swab test of SARS-CoV-2 after birth. 4. Follow-up to Mar 7, 2020, no maternal and neonatal deaths MESHD occurred.Conclusions: The majority of patients in late term pregnancy with COVID-19 were of ordinary type, and they less likely developed into critical pneumonia MESHD pneumonia HP after early isolation and antiviral treatment. Vertical transmission TRANS of SARS-CoV-2 was not detected, but the proportion of neonatal bacterial pneumonia MESHD pneumonia HP was higher than other neonatal diseases MESHD in newborns.
