Bird flu spreads to urban Bangladesh: Widespread Across the Nation

DHAKA, Feb 6 (Reuters) - Bird flu has spread to the Bangladesh capital Dhaka and to the port city Chittagong despite efforts by authorities to contain it, livestock officials said on Wednesday.
 
Dozens of dead crows found over the past two days in Dhaka have tested positive for the H5N1 strain of bird flu. City authorities have ordered a ban on the sale of undressed chicken in Dhaka markets, the officials said.
 
In Chittagong, officials confirmed the spread of bird flu in several farms and also in crows that tested positive for the strain.
