COVID 19 is a communicable disease which has spread all over the world due to human-to-human transmission. The initial symptoms are non specific, and it presents with fever and cough, which can then resolve spontaneously or progress to acute respiratory distress syndrome (ARDS), multiple organ failure, and death. This is a retrospective study conducted in a tertiary care center in Delhi to find out association of factors like age, gender and various co morbidities on COVID-19 mortality. Male patients with older age and having co morbidities were found to have higher mortality and results were statistically significant.
