Objective: Epidemiological evidence shows that the prevalence of patients with comorbidity of diabetes mellitus (DM), in Coronavirus disease 2019 (COVID-19) is remarkable and they have poor prognosis. We aimed to investigate the comorbidity of diabetes and covid-19 in positive Polymerase Chain Reaction people in Yazd.

Results: Prevalence of COVID-19 patients with diabetes was 27% and the percentage of male patients was 62.6%. Additionally, duration of hospitalization significantly higher in diabetic patients (P= 0.004), need to invasive mechanical ventilation in diabetic patients was significantly higher than non-diabetic patients (P˂ 0.001) Conclusion: DM is one of the most important comorbidity with COVID-19 patients and this comorbidity affects the severity of the disease and the outcome of patients.
