Vietnamese authorities reported on Monday that bird flu has spread to seventh province in the country’s south. Avian flu outbreaks have led to the killing of thousands of birds in Vietnam’ s Mekong delta in the past month.
    Thai livestock officials say they have just culled ducks in a northern province, the first flu outbreak in poultry in six months.
    In Japan, agricultural authorities began culling thousands of chickens at a south poultry farm on Sunday after tests found they were infected with bird flu. In China’s Hong Kong, a dead bird suspected of having the H5N1 strain of avian influenza was found last Saturday, the second in two weeks.
    Bird flu has also claimed human lives. Four people died of avian influenza in Indonesia last week. The son and husband of one the victims are being treated for symptoms of bird flu. Officially say, however, that there is no evidence of human-to-human transmission.
    Peter Cordingley, spokesman for the World Health Organization’ s regional office in Manila, says the recent outbreaks prove Asian needs to remain vigilant.
    Cordingley urges continued education about the dangers of living in close proximity to infected poultry, particularly in Indonesia, where more than 60 people have already died of avian influenza.
    Bird flu featured prominently at the meeting of the Association of South East Asian Nations in Manila. Leaders endorsed a bird flu-prevention "road map" aimed at sharing best practices in the region.
