The Hyderabad-based Asian Institute of Gastroenterology (AIG) founder, Dr D Nageshwar Reddy is a world-renowned doctor for many pioneering work in medicine. AIG formed a 52-member strong doctor’s team drawn from various faculties for in-depth study of the second Covid surge. It will look at steroids and antibiotics being prescribed for Covid patients, use of oxygen and concentrators, the reason for black fungus and so on. They came up with a Covid treatment protocol which was carried out on 20,000 seriously affected patients and almost all of them were saved. Reddy, who has been accorded the Padma Bhushan and the American Society of Gastroenterology Crystal Award, says India could overcome the pandemic by the year-end if the AIG treatment protocols are followed religiously along with a vigourous vaccination drive, in an interview to M S Shanker of Outlook.
