ICMR director general Balram Bhargava said there is no difference in deaths between first and second wave among hospitalised patients, while the oxygen requirement is higher in second wave and ventilator requirement is not higher in the second wave.
Prevalence of shortness of breath is slightly higher in the second wave of Covid-19 but sore throat and dry cough and other symptoms were higher in the first wave.
“No difference in deaths between first and second wave among hospitalised patients. About 54.5 percent patients require oxygen in second wave against 41.5 percent in the first wave. More than 70 percent patients in both waves are more than 40 years old, only marginally higher proportion of younger patients. Higher proportion of asymptomatic patients in the second wave,” he said, based on the study of 1,885 patients in second wave and 7,600 in the first wave.
