Women who experience Covid-19 infections within a week before giving birth are at an increased risk for severe maternal morbidity (SMM) events, including acute renal failure and adult respiratory distress syndrome (ARDS), according to study.

An international team of researchers from the US, Canada and Australia showed that the risk of SMM was 2.22 times higher among women with SARS-CoV-2 infection within 7 days of delivery and 1.66 times higher among those with infection 7-30 days prior to delivery compared to those who were uninfected.
