Juan Lubroth Introduce Quotations

I think that wild birds may introduce the virus but it is through man and man's marketing systems (the poultry trade) that the disease spreads. It is also possible that poultry can transmit the virus to wildlife when they share the same ecosystem.

It's very easy to blame bird migration, because then no one's responsible. Migrating birds may introduce the virus into an area, but it is human activity that spreads it.
