WHY is it such a killer! because it is a virus and not bacteria, antibiotics will not help -- for example: "the flu" constantly has newer, mutated versions because it, too, is a virus. These bugs change and the big pharma boys know what has been the top stocks last year. The biotech firms and funds want the trend to continue. THEY can not miss the next Intercept Pharmaceuticals (ICPT) that went from 20 to 500 dollars in two years. This stock is granted new testing and test because of DEMAND ! Fidelity had the most ICPT in their portfolio and they are smart cookies. I bet they will buy.
