Background-India,like many countries,has experienced two surges of the COVID 19 pandemic.Empirical data shows adifference in the effects of the virus between the two periods.We decided to compare the behaviour of the disease in itstwo major outbreaks in critically ill patients so as to obtain a better understanding and improve clinical outcomes.Methods- This was a retrospective study conducted by obtaining patients data from hospital records during the firstst wave from 1 April 2020 to 30 June 2020 and comparing it to the records in second wave 15 March 2021 to 15 June 2021.Patient demographics,clinical presentation,mechanical ventilation and overall ICU outcomes were compared.Results- 89 patients admitted during first wave and 100 patients admitted during second wave during the chosen periodwere selected for the purpose of this study. Second wave predominantly involved the young and middle aged whilemajority of patients during first wave belonged to older age group with co morbidities. The most frequent signs andsymptoms during both waves were fever,cough,pneumonia and tachypnea.Conclusion- The second wave was characterised by higher infectivity in a comparatively younger age group whereasfirst wave showed older age groups being primarily infected. However, the case fatality rate during first wave washigher than second wave.
