Objective: To describe the prevalence and characteristics of seropositive pregnant women for SARS-CoV-2. Material and methods: Quantitative, cross-sectional and descriptive study. Performed in pregnant women screened for SARS-CoV-2 who met selection criteria at hospital admission. Variables of maternal characteristics, pregnancy complications and newborn condition were collected from the respective medical history. Data analysis was performed using descriptive statistics and 95% confidence intervals. Results: 1477 pregnant women admitted to hospitalization were screened, identifying a seroprevalence of anti-SARS-CoV-2 antibodies in 5.28% (95% CI: 4.22% -6.57%). Among the cases of positive seroprevalence, IgM 11.5% (95% CI: 5.7% -21.3%), IgM / IgG 64.1% (95% CI: 5.7% -21.3%), IgG 19% (95% CI: 15.7% and 35.6) were observed %), 91% of seropositive pregnant women were asymptomatic, 40% of se...

Introduction: COVID-19 disease spreads rapidly. Seroprevalence in pregnant women entering for hospitalization and clinical characteristics in this type of population in Peru is not known. Objective: To determine the prevalence and clinical-epidemiological characteristics of pregnant women with anti-SARS-CoV-2 antibodies at a level III hospital in Peru. Methods: Observational and cross-sectional study performed at the National Maternal Perinatal Institute of Peru. Pregnant women admitted for hospitalization were screened for COVID-19 infection. Results of anti-SARSCoV-2 serological tests and information on maternal and perinatal characteristics were obtained. Data analysis was performed using descriptive statistics and 95% confidence intervals. Results: In 2 419 pregnant women screened we identified a prevalence of 7.0% of anti-SARS-CoV-2 antibodies (95% IC: 6.1% to 8.1%), including IgM i...

Introducción. La enfermedad de COVID-19 se propaga rápidamente. Se desconoce la seroprevalencia en mujeres embarazadas que ingresan a hospitalización y sus características propias en este tipo de población en Perú. Objetivo. Determinar la prevalencia y características clínico-epidemiológicas de gestantes con anticuerpos anti-SARS-CoV-2 en un hospital nivel III de Perú. Métodos. Estudio observacional de tipo transversal, realizado en el Instituto Nacional Materno Perinatal de Perú, entre el 15 de abril y 15 de mayo de 2020. Participaron todas las gestantes que ingresaron a hospitalización y fueron tamizadas para la infección por SARS-CoV-2 mediante pruebas serológicas, cuyos resultados fueron analizados conjuntamente con sus características clínicas y epidemiológicas, utilizando estadígrafos descriptivos e intervalos de confianza al 95%, y mediante la prueba de independ...
