It's actually making a comeback in Asia. 'Course, there's H1N1, H5N1, H7N9, H10N8, etc. The ptarmigan scientists really have it in for humanity. 
Anyone remember Typhoid Mary from long ago, a woman that was a carrier of the disease but herself not effected by it.
If I remember correctly, Mary was a cook and most everyone that came into her places of employment became sick.
Some how she was tracked down and ordered by a Court to never work as a cook again. Off she went and as cooking was her livelihood soon went back to her trade.
Sad, a poor woman who was healthy herself and very ignorant told she was spreading disease and killing those that ate her cooking.
Must have been a nightmare to be told she was responsible for the deaths of so many people when she had done nothing wrong.
She did end up in prison I do believe and I have no idea what happened to this poor thing.
So for the Bunny's that have done no wrong themselves that carry and spread a disease. Not their fault but they must be removed for the good of all, not just for the good of some bird I never heard of.
