BANGKOK, Thailand - Millions of volunteers led by emergency teams fanned out across Thailand today in a new drive to fight bird flu after the prime minister gave officials 30 days to eradicate the epidemic.

In China, local officials have been put on "high alert" against bird flu and ordered to step up disinfection and surveillance of poultry after Thailand reported possible human-to-human transmission of the disease.

China's Agriculture Ministry told officials to stockpile vaccines, warning that "the epidemic, still haunting some Asian countries, poses a risk to China," the official China Daily newspaper reported. Officials were told to disinfect farms, slaughterhouses, markets, refrigerator warehouses and shipping, the report said.

The bird flu scare grew after Thailand reported that its latest bird flu victim likely contracting the virus from her daughter, the first probable case of human-to-human transmission in the country.

Ten people have died of bird flu in Thailand and 20 in Vietnam, while more than 100 million chickens and poultry have died or been culled to stop it since a severe strain of the virus spread across large swaths of Asia early this year.

Thai Agriculture Minister Somsak Thepsutin today said his nation's offensive against the disease "begins from this minute."

Somsak told reporters that livestock officials are directing "millions of volunteers and officials ... to X-ray every spot nationwide, to cull the sick chickens and properly bury them."

He said Thailand had faced setbacks in fighting bird flu, or avian influenza, blaming rural villagers for ignoring government rules that require them to inform officials when they have found dead chickens and provide complete health records when they enter hospitals.

"When a small number of chickens die, people think, 'never mind' and keep the information to themselves," Somsak said. "But from now on, volunteers will go into every village and report every single case to officials."

The anti-bird flu drive began after Prime Minister Thaksin Shinawatra declared a national war against the disease on Wednesday. He gave ministers until Oct. 31 to wipe out the disease or face the sack.
