COVID 19 causes health as well as an economic burden all over the world causing significant mortality and morbidity. The second wave of COVID 19 occurred in March 2021 in India causing large numbers of severe infections and also the vaccination drive was started during January 2021. Previous studies proved that various factors were associated with mortality and this study was conducted with the objective of estimating the prevalence of mortality and also the factors associated with it, especially in relation to the vaccination status. Methodology: A cross-sectional study was conducted in a tertiary care hospital among the COVID 19 patients during the months of June and July 2021. A semi-structured questionnaire was used containing the basic details about the patient and the relevant clinical details. A universal sampling method was employed and those patients who were below the age of 18 years were excluded. Data collected were entered in MS-Excel and analysis was done using SPSS software version 21.Results:A total of 226 patients were included in the study. Most of the study subjects were in the age group of >45% (73.5%) and the majority were males. Nearly 42 % of them had any one of the comorbidities and only 11.5 % of them were vaccinated against COVID 19. The prevalence of mortality was 21.2% and the factors associated were age, co-morbidity status, duration of hospital stay, disease severity, and the vaccination status. Conclusion-Vaccination against COVID 19 had less risk of morality even though other factors could influence it. Hence further research is needed to explore other factors that might affect both morbidity and mortality.
