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).
