Revisiting the endocrine and metabolic manifestations of COVID-19 two years into the pandemic.

An extraordinary effort of the universal endocrine community has led to important insights into endocrine and metabolic aspects of COVID-19. In this Editorial, we introduce a special issue of Reviews in Endocrine and Metabolic Disorders that calls attention, through the efforts of internationally recognized experts in the field, to features that are now widely recognized as endocrine and metabolic manifestations of COVID-19. These advances in our knowledge have seminal implications for how we can prevent and manage these aspects of COVID-19.
