If the ROD was in one of those areas of the world prior to Puna then we would have heard about it during this ROD outbreak. All we hear is that the ROD is a new never been seen, documented or identified anywhere else in the world fungus. Did folks from Asia,Africa or S. America ever travel to Puna before this past decade or did Puna just recently start getting visitors from those parts of the world??
