Introduction – Dengue fever is a highly prevalent infectious disease that is rapidly increasing worldwide. There is a connection between Diabetes Mellitus and long-term inflammation.The aim of present study was to find out the correlation between diabetics and non diabetics recovery in hospitalised dengue positive patients. Material and methods – The prospective observational study was conducted at a tertiary care centre among 100 admitted dengue patients [50 were diabetic (Group A) and 50 were not diabetic (Group B)] during the study period of one year. Clinical and demographic data was recorded and results were analyzed using SPSS version 25.0. Results – The levels of all three inflammatory mediators were higher in patients with both dengue and diabetes compared to those with dengue alone. These differences were also found to be statistically significant (p < 0.05). Mortality rate (4/50) was higher in those having diabetes with dengue. Conclusion – Patients with dengue and diabetes mellitus are more susceptible to bleeding disorders, which can lead to illness and death. This is due to the activation of inflammatory processes that cause high blood sugar levels and poor control of blood sugar.
