"The epidemic situation is worsening," says Agriculture Vice-Minister Bui Ba Bong.
Outbreaks could spread across the country with cooler weather and the increased movement of poultry and people in the coming weeks before Vietbam's
New Year, Bong warns.
Ducks can carry the H5N1 virus without showing symptoms, as can people, which makes monitoring outbreaks more difficult.

Vietnam Faces Bird Flu Resurgence
Vietnam's glory as star performer in fighting avian influenza in 2006 is being stripped as the deadly virus reappears in the southern Mekong Delta
region. February may see the epidemic sweeping through the entire country, officials warn.
...of the more than 50 countries where the virus has been detected, Vietnam had stood out as a model of how this deadly strain could be contained. A
national programme of culling, vaccinating poultry, shutting down open chicken markets and an awareness campaign saw Vietnam without a bird flu case
for an eight-month stretch, since December 2005.
That achievement came in the wake of a looming crisis, where Vietnam had the highest human death toll due to bird flu by end 2005 and some 44 million
birds, an estimated 17.5 percent of its poultry population, had died or been slaughtered since the 2203 winter H5N1 outbreak.

Vietnam's bird flu spreading
Vietnam government reported that H5N1 bird flu is spreading and spread of avian bird flu virus has reached to Vietnam's largest urban area of Ho Chi
Minh City. 20 chickens were found dead on a farm in Vinh Long province confirmed the presence of the virus.
The Vietnam experience shows that once disease is allowed to become endemic, it is difficult if not impossible to eradicate.
