GAUHATI, India — Health workers have killed about 4,000 ducks and chickens at a government-run farm in the remote northeastern Indian state of Tripura after some tested positive for bird flu, a government official said Sunday.
Sixteen public health teams also began slaughtering poultry within half a mile (one kilometer) of the state-run farm in an attempt to halt the spread of the virus, said Jyotirmoy Chakrabarty, joint director of the state's animal research department.

More women opting for preventive mastectomy - but should they be?
Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have increased by an estimated 50 percent in recent years, experts say. But many doctors are puzzled because the operation doesn't carry a 100 percent guarantee, it's major surgery -- and women have other options, from a once-a-day pill to careful monitoring.

Chakrabarty said some poultry on the government farm were infected with the H5 strain of bird flu, and more tests were under way to determine whether it was the virulent H5N1 subtype.
There were no reports of any humans being infected, he said.
"There is no cause for panic. We are eliminating the birds since they have tested positive for the H5 virus," Chakrabarty said.
The state government has banned the movement and sale of poultry and eggs from farms in the area, on the outskirts of Agartala, the state capital.
State authorities have also banned the import of poultry and eggs from Bangladesh, which is six miles (10 kilometers) from Agartala.
The last major outbreak of bird flu in India was in 2008, when millions of poultry were slaughtered. Minor outbreaks were reported in 2010.
