Asymptomatic SARS-CoV-2 infection was only associated with increased risk for maternal morbidity and preeclampsia. 13% of neonates delivered from PCR-positive women also tested positive. Cesarean delivery, but not breastfeeding, was significantly associated with neonatal test positivity.

Mean monthly hospital admissions for AHT across 49 US hospitals were lower from March to September 2020 compared to the same period in 2017-2019.
