Turkey Bird flu killed a second teenager in eastern Turkey early Thursday, one day after health officials confirmed her brother as the first fatality by the virus outside of East Asia.
Fatma Kocyigit, 15, died four days after her brother in the same hospital where four members of the family were admitted several weeks ago, according to the semi-official Anatolia news agency.
Tests confirmed both teens were infected, the agency said.
The health minister, Recep Akdag, said Muhammet Ali Kocyigit, 14, apparently contracted the virus from ailing chickens at his family's rural home in the shadow of Mount Ararat, near the Armenian border. Lung tissue from the boy tested positive for the H5N1 virus at two Turkish labs and was being sent to a World Health Organization laboratory in London for more tests.
The boy, who died Sunday, was one of a dozen people with similar symptoms admitted to the hospital in recent days.
