Most had a good evolution and the case fatality rate was < 1% (n = 1). At the time of this analysis, 78% of the women had completed pregnancy. 41% of them presented some type of complication, the most frequent being: premature rupture of the membrane 42%, arterial hypertension and other associated pathologies (including a patient with preeclampsia) 27% and preterm delivery 18%. In the comparative analysis between the first two pandemic waves, there was a higher proportion of moderate/severe cases (p = 0.016) and the indication for mechanical ventilation was significantly higher (p = 0.048) in 2021.DiscussionThese findings support the need for prioritize this group of patients to implement preventive strategies.
