It is known that during pregnancy some viral infections significantly affect fetal development and normal physiological changes in the pregnant woman's body increase susceptibility to respiratory diseases. Thus, pregnant women are more likely to be infected with SARS-CoV-2 and to become ill with COVID-19 than the general population. They are at increased risk of hospitalisation, ventilatory support and other subsequent maternal, fetal and neonatal health problems. Severe COVID-19 infection during pregnancy has been associated with increased adverse perinatal outcomes, although studies differ as to which outcomes it may affect. More detailed characterisation of obstetric and neonatal outcomes is needed, including details of indications for preterm birth and additional neonatal adverse outcomes.
