Chickens best left alone unless fried and crispy

The bird flue killed a young Thai boy, Asia's 70th victim of the deadly virus, authorities said on Friday,

China also reported a new case of H5N1, the fifth person in the country known to have been infected with the deadly virus. The 31-year-old woman, who lived in the Heishan county of Liaoning province, has since recovered.

The death of the 5-year-old boy from the central province of Nakhon Nayok, took Thailand's bird flue death toll to 14 out of 22 known cases since the virus swept through large parts of Asia in late 2003.
He was the second Thai killed by the H5N1 virus since bird flue erupted anew in the country in October, when a 48-year-old man died.

The boy, who died in hospital on Wednesday, was not known to have had direct contact with chickens, health officials said. But there are chickens raised in his neighbourhood," said Thawat Suntrajarn, head of the Health Ministry's Disease Control Department. This has not however douse fear that the H5NI may not mutate into a form which could pass easily from person to person, setting off a pandemic which could kill millions of people without immunity to the new strain.

Questions: Should people be isolated from chickens? Or should chickens be isolated from birds?
I believe this is an economic question.
