Avian Influenza Risk Environment: Live Bird Commodity Chains in Chattogram, Bangladesh.

Structural constraints may reinforce risky occupational practises and limit individual agency. Structural constraints need to be addressed in order to tackle animal and zoonotic disease risk along live animal commodity chains.
