Abstract
COVID-19 has become a major global health problem. COVID-19 teaches us many things, one of which is the relationship between COVID-19 and diabetes. Recent evidence suggests that the coronavirus may cause diabetes. In addition, the term new-onset diabetes in COVID-19 was introduced in 2020, and evidence has been reported. It poses a new challenge to the clinical management of COVID-19 patients. The pathophysiology of this disease is still not fully known. However, hypotheses have been proposed. Therefore, we write this literature review to add insight into new-on set diabetes in COVID-19 patients.
