Preliminary data published in 2021 strongly suggested that testing positive for Covid was linked to a traumatic stress response during pregnancy and childbirth. According to a study from 2022, ‘pregnant mothers reported fear of infection, fear of vertical transmission, fear of poor birth and child outcomes, social isolation, uncertainty about their partner’s presence during medical appointments and delivery, increased domestic abuse, and other collateral damage, including vaccine hesitancy.’ During the first two years of the pandemic, maternal mortality rose in the United States (especially among Black and Hispanic communities), Japan, Australia and the Netherlands.
