Scientists are hailing a steroid treatment as a major breakthrough in the fight against COVID-19. Trial results show Dexamethasone is the first drug to reduce death rates by about a third in the most severely ill coronavirus patients. The cheap and widely used steroid reduces inflammation. Researchers say it should be immediately used as standard care in patients who have severe cases. To date, more than 438-thousand people have died during the pandemic worldwide, including 116-thousand in the U.S. The cost is low as one dollar a day.
