Core Tip

Core Tip: This review highlights the significant correlation between diabetes mellitus and coronavirus disease 2019 (COVID-19) in light of available published information. COVID-19 is responsible for increased risk and disease severity in diabetic patients. Cytokine storm, destruction of beta cells and the expression of angiotensin converting enzyme 2 are some of the fundamental mechanisms discussed. This review also summarizes the range of investigations that have been undertaken across a large set of published papers on COVID-19 and diabetes mellitus.
