RESUMEN Objetivo Buscar toda la informacion y evidencia disponible sobre el SARS-CoV-2 -que surgio en estos primeros 4 meses de 2020y el embarazo Metodologia Revision sistematica en las bases de datos PubMed y Google Scholar, hasta el 25 de abril de 2020 Se busco articulos publicados relacionados con mujeres embarazadas infectadas con SARS-CoV-2 No hubo restriccion de idioma La busqueda se extendio a las referencias de los articulos encontrados Resultados La enfermedad COVID-19 en mujeres embarazadas se caracteriza porque mas del 90% de las pacientes evoluciona en forma leve, 2% requiere ingresar a las unidades de cuidados intensivos Una muerte materna ha sido reportada La prematuridad es alrededor de 25%, con predominio de recien nacidos prematuros tardios;aproximadamente el 9% se complica con rotura prematura de membranas;la mortalidad perinatal es baja o similar a la de la poblacion general y no se ha demostrado la transmision vertical Conclusiones Los ginecologos obstetras deben prepararse para atender cada vez mas casos con COVID-19 y, por lo tanto, es necesario tener su conocimiento La enfermedad evoluciona de la misma manera que en las no embarazadas, genera mayor prematuridad, no se ha demostrado la transmision vertical, pero hay altas posibilidades de transmision horizontal durante el parto vaginal ABSTRACT Objective : To search for all the information and available evidence on infection with SARS-CoV-2, a virus that appeared during the first 4 months of 2020, and pregnancy Methods : Systematic review in PubMed and Google Scholar databases until April 25, 2020 We searched for published articles related to pregnant women infected with SARS-CoV-2 There was no language restriction The search was extended to the references of the articles found Results : In pregnant women with COVID-19, more than 90% of patients evolve mildly, 2% require intensive care One maternal death has been reported Prematurity occurs in approximately 25% of the cases, with predominance of late preterm infants;premature rupture of membranes presents in about 9% Perinatal mortality is lower or similar to that of the general population, and vertical transmission has not been shown Conclusions : Obstetrician-gynecologists must prepare to attend more cases with COVID-19 and therefore they need to know this disease COVID-19 progresses similarly in pregnant and non-pregnant women, although it is associated to prematurity While vertical transmission has not been demonstrated, horizontal transmission during vaginal birth is very likely
