COVID-19 in pregnancy.

Evidence continues to emerge on the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) in pregnancy. Compared with previous coronavirus outbreaks (severe acute respiratory syndrome and Middle East respiratory syndrome), recent reports suggest that pregnant women who contract SARS-CoV-2 have lower rates of maternal and fetal complications; however, the incidence of preterm birth remains elevated. The potential for vertical transmission is still under investigation. Universal testing of women admitted to labor and delivery is being encouraged in most centers.
