Main Findings
SARS-CoV-2 was detected in vaginal swabs of two pregnant women with COVID-19 and in placental swabs of two severe fetal cases after maternal COVID-19. Within the first eight days of a positive pharyngeal swab, SARS-CoV-2 antibodies were detected in only 7.7% of the women, while SARS-CoV-2 antibodies were observed in 90.5% women tested more than eight days after a positive swab. Antibodies in umbilical cord blood were not detected within the first 16 days after the mother was tested positive, hereafter, antibodies were present in 94.1% of cord blood samples of seropositive mothers. We observed two severe fetal outcomes both associated with maternal admittance due to reduced fetal movements, pathological or preterminal CTG, delivery by emergency preterm caesarean section, and abnormal placental histopathological examinations.
