I can't think of any drugs that kill bacteria or viruses off the top of my head. The drugs we have just interfere with some part of their biology. You need intact immune systems to literally kill them off, at least that's what I was taught.
I was disappointed the article did not discuss the mechanism for this discovery. Is it cell signaling or the way the virus hides from the immune system? I was taught the same, also whatever is being used to inhibit the bug must also be designed to be non- toxic to us when we use it to fight infections.
