This a great news for sure. With the advancement of technology and medicine we are bound to find the cure, probably within the next decade or so. However, with this new discovery I would hope that it doesn't cloud people's judgment and give them a false sense of hope. You should still get tested and you should should still play safe at all times. This method isn't set in stone yet and will still take years to perfect before it bears fruit for us to enjoy so until them please use common sense, show responsibility and common courtesy to yourself and your fellow man.
A false sense of hope will often lead you down a path of pain and misery so don't be fools, guys. Wrap your tools and know yours and others status.
