This study aims to detect the SARS-CoV-2 infection prevalence in asymptomatic pregnant women.
A group of 195 asymptomatic pregnant women who attended the prenatal care outclinic and to the obstetric emergency department was tested concomitantly for SARS-CoV-2 by RT-PCR and serological tests.
The virus was detected by RT-PCR in two (1.02%) cases and 17 (8.71%) patients had antibodies detected by immunochromatographic tests.
Due to the high risk of this emerging infection in the health of pregnant women, fetuses and newborns, we suggest the universal screening of all pregnant women admitted to hospital through the combined method RT-PCR and serological.
