Abstract
Patients with diabetes are one of the risk factors for not only increased sepsis but also rapid progression and severe prognosis of COVID-19. Therefore, patients with diabetes need to be closely monitored, the importance of glycosylation, viral protein mutations and ACE2r. Better glycemic control is required in patients with hyperglycemia on admission. Pre-diabetes and diabetes are potential mechanisms for slowing the spread of COVID-19 and reducing symptoms and improving treatment outcomes. We know that glycemic control is essential for COVID-19 patients and even patients without COVID-19. However, hyperglycemia remains a strong prognostic factor for the prognosis of hospitalized COVID-19 patients.
