The Daily Star, a Bangladeshi news source, has an excellent article on what the country should do If bird flu hits.
Even if it only infects chickens and does not affect a single human, the disease certainly has the ability to wreck Bangladesh's poultry industry. This will impact on the millions of people directly or indirectly supported by chicken farming across Bangladesh.
The government needs to implement an outbreak management plan. Such a plan has been written, but little implementation is visible and practically nothing has been publicized.
The author of the article runs "one of the largest poultry hatcheries in Bangladesh," and he seems very well-informed.
