Conclusion
Diabetes appears to be a common morbidity in patients affected by COVID-19 however, the evidence that it increases the risk of infection is not yet clear. On the other hand, the evidence that diabetes increases the risk of severe disease and risk of adverse outcomes is substantial. Patients with diabetes who are at risk of COVID-19 tend to be obese, of older age, have uncontrolled diabetes and comorbidities, in particular cardiovascular disease and hypertension. Further research is still required to investigate appropriate management of people with diabetes and COVID-19 and develop novel ways of management including telecare.
