Clinical Trial Summary

The SARS-CoV-2 infection may behave differently in pregnant and postpartum women in the short and long term. Several risk factors or medication use can interfere on disease' evolution and vertical transmission. Thus, due the current pandemic and the scarcity of scientific studies involving pregnant women with covid-19 or positive serology, combined with the need to elucidate the behavior of this viral infection in pregnant women in our population, this study aims to evaluate the clinical and laboratory evolution, transplacental passage, gestational and neonatal outcomes in pregnancies with positive SARS-CoV-2.
