Current evidence of SARS-CoV-2 infection in pregnancy: A scoping review

Introduction: SARS-CoV-2 is a betacoronavirus as well as SARS-CoV and MERS-CoV, both associated with spontaneous miscarriage, preterm birth, maternal morbidity and mortality and a higher number of ICU admissions for pregnant women. Being a new virus, its effects on pregnancy are little known.This review aims to analyze the available evidence on SARS-CoV-2 in pregnancy. Materials and Methods: A literature review was conducted in PubMed, ProQuest, Scopus, BVS and SciElo. Evidence criticism and information extraction were conducted using two instruments from the Joanna Briggs Institute, following the PRISMA-ScR guidelines. Results: 85 articles were included evidencing that most pregnant women with SARS-COV-2 suffered mild to moderate disease and were at a higher risk of death and complications compared to non-pregnant patients. Low risk of vertical transmission was documented and adverse perinatal outcomes were associated with severe maternal clinical manifestations. The effectiveness of treatment was inconclusive. Discussion: Clinical presentation of infection in pregnant women, vertical transmission, treatment, disease severity and neonatal outcomes were discussed. Conclusions: COVID-19 during pregnancy is a complication that generates greater morbidity and mortality, for which it is vital to develop further research on the understanding of the behavior, physiological and emotional implications and possible treatment. This review makes a rigorous analysis of the quality of studies and provides valuable information from evidence.
