The Avian flu never really developed into a human health hazard.
Maybe this bat flu will. It could.
Health organizations need some health scare to bring in the bucks from the politicians.
After all, that bat flu has already killed 3 people in Australia.
Many of these plagues have very long cycles and depend on so many factors they don't spike until everything is just right ~ currently we are just coming out of another episode of the recurring solar driven 80/85 year drought cycle ~ that affects both hemispheres ~ although in different ways.
The hanta virus plagues in North America have always followed the big droughts. Airborn rabies just takes the cake.
