The information will be analysed on a continuous basis to inform ongoing guidance for women and maternity staff as we respond to the pandemic. Specifically, the study will describe incidence, management and outcomes of COVID-19 in pregnancy and identify factors associated with better outcomes for women and their babies. Anonymous information will be collected through the existing UK Obstetric Surveillance System (UKOSS) reporters, who are based in all maternity units in the UK. Reporters have been sent a live link to allow them to notify cases and complete an anonymous data collection form.


  • 1. Any pregnant woman hospitalised who has tested positive for COVID-19 will be included.
