China confirms H5N1 strain of bird flu among ducks

China, which raises more poultry than any other country in the world, has vowed an aggressive fight against H5N1, which has sickened at least 328 people worldwide, killing 200 of them, according to the World Health Organization.

China has reported 25 human cases of bird flu since 2003, 16 of them fatal.

Experts have warned that if poultry outbreaks are not controlled, the virus may mutate into a form more easily passed between people, potentially resulting in millions of deaths.

Chow said Hong Kong will suspend chilled and frozen duck and geese from southern Guangdong province, where Panyu is located, for a week.
