Amid the scramble for the anti-viral drug remdesivir, AIIMS chief Dr Randeep Guleria clarifies on COVID-19 treatment protocol. He says remdesivir, if given for five days, can decrease hospital admissions, but does not reduce deaths. "There is mixed data about remdesivir's efficacy, that's why it's in emergency use category in India. It has side effects and should be given under medical supervision," Dr Guleria says.
