COVID-19 and Diabetes: An Epidemiologic Overview

Past literature on the development of type 1 diabetes (T1D) and type 2 diabetes (T2D) has emphasized the influence of exogenous factors, including viral infections, in the development of these conditions. The coronavirus disease 2019 (COVID-19) pandemic again highlighted the complicated connection between viral infection and the development of diabetes. The complex interplay of proinflammatory, genetic, and socioeconomic factors can help explain the increased incidence of T1D and T2D during the pandemic. Proposed pathophysiological mechanisms connecting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to T1D include the expression of angiotensin enzyme 2 receptors on pancreatic islet cells, resultant proinflammatory states, and potential transient damage caused by viral entry. The intricate web of genetic factors, social determinants of health (including the rise of obesity), and the impact of proinflammatory states during SARS-CoV-2 infection on insulin resistance suggests mechanisms linking SARS-CoV-2 infection to the development of diabetes.
