Since 31 December 2019 and as of 7 April 2020, over 1.3 million (1 316 988) cases of COVID-19 have been reported worldwide, and more than 70 000 (74 066) deaths. Half of these cases (608 500) have been reported from the EU/EEA countries and the UK, and over 50 000 (51 059) of them have died. Overall, large increases in COVID-19 cases and deaths continue to be reported from the EU/EEA countries and the UK. In addition, in recent weeks, the European all-cause mortality monitoring system showed all-cause excess mortality above the expected rate in Belgium,
Background: Clinical presentation and outcomes of COVID-19 infection during pregnancy remain limited and fragmented. Objectives: To summarize the existing literature on COVID-19 infection during pregnancy and childbirth, particularly concerning clinical presentation and outcomes. Search strategy: A systematic search of LitCovid, EBSCO MEDLINE, CENTRAL, CINAHL, Web of Science, and Scopus electronic databases. The references of relevant studies were also searched.Selection criteria: Identified titles and abstracts were screened to select original reports and cross-checked for overlap of cases.
Data collection and analysis:A descriptive summary organized by aspects of clinical presentations (symptoms, imaging, and laboratory) and outcomes (maternal and perinatal).
Main results:We identified 33 studies reporting 385 pregnant women with COVID-19 infection: 368 (95.6%) mild; 14 (3.6%) severe; and 3 (0.8%) critical. Seventeen women were admitted to intensive care, including six who were mechanically ventilated and one maternal mortality. A total of 252 women gave birth, comprising 175 (69.4%) cesarean and 77 (30.6%) vaginal births. Outcomes for 256 newborns included four RT-PCR positive neonates, two stillbirths, and one neonatal death.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
