Preeclampsia and COVID-19 share pathophysiological similarities in pregnant women

During the COVID-19 pandemic, above all before vaccines were available, an alarm was sounded regarding a possible correlation between severe cases of COVID-19 in pregnant women and preeclampsia, a condition characterized by high blood pressure (hypertension) in the expectant mother and high levels of protein in her urine (proteinuria). It can entail dangerous complications for mother and baby.
