Cockfighting is Spreading Bird Flu in Asia

The traditional sport of cockfighting is helping spread avian flu in Asia, due to the close contact between the birds and their owner/handlers.

Meantime, international health officials are calling on Asian farmers to vaccinate their poultry rather than kill the fowl -- as the birds most likely to have avian flu are wild ones that are the hardest to catch and kill. That doesn't quite make sense to me (if you can't catch them to kill them, how can you catch them to vaccinate them?), but then I'm not an international health official.
