The Thai government will soon declare Thailand as a bird flu free zone with no more poultry in the kingdom infected with H5N1 avian flu virus.

The Ministry of Agriculture and Cooperatives reported the latest bird flu situation to the cabinet at its weekly meeting here on Tuesday, saying that there is now only one area in the kingdom which is under a close surveillance on an avian flu outbreak, reported the Thai News Agency Wednesday.

The only area under the state close observation is Wat Chalo Sub-district in Bang Kruay District of Nonthaburi Province on the outskirts of Bangkok, Thai Government Spokesman Surapong Suebwonglee was quoted by the agency as saying.

"If there is no more H5N1 virus found among poultry flocks in the sole observation area after Nov. 29, all parts of Thailand will be free from bird flu outbreaks and the country can be declared a bird flu free zone," Dr. Surapong said with Thailand's success in containing three avian flu outbreaks so far.

The Thai authorities will, however, continue to prevent any re-emergence of the deadly disease among local poultry flocks, he added.
