when it's developed, this crisis already ends. then this virus hides again in the wild. in the unlikely event it comes back, chances are it mutates so much that the vaccine would be inffective. sars, swine flu(h1n1) similar story.

small farms for fowls and pigs integrated into modern middle to large ones.

none would be easy. ned government and public to work together. no other options. price too high as shown now.
