A total of 200 patients, with 100 from each period were included in the study. Major comorbidities in patients included hypertension, diabetes mellitus and pulmonary disease. Patients who succumbed to the Delta variant (26%) were higher as compared to the Omicron variant (10%); with the elderly (68 ± 9.7 years) having mortality during the Omicron variant. A significantly increased risk for mortality was observed in comorbidities in both Delta and Omicron variants with hypertension (OR:1.3;5.44), diabetes mellitus (OR:0.99;1.94), chronic pulmonary disease (OR:1.6;2.25), chronic kidney disease (OR:3.18;0.89), and smoking (OR:1.74;1.55).
