The 32-year-old woman from Tangerang died at her home lastThursday after her family had taken her out of a hospital whereshe had been receiving treatment a day before, said SuhardaNingrum of the health ministry's bird flu centre.
Contact with sick fowl is the most common way ofcontracting bird flu, endemic in bird populations in most ofIndonesia.
"She bought a live chicken and some eggs from a market andcooked them," Ningrum said, adding there were also chickensliving in her backyard.
Two tests at two different laboratories confirmed the H5N1virus.
Although bird flu remains an animal disease, experts fearthe virus could mutate into a form easily passed from human tohuman and kill millions.
On Christmas day, a 24-year-old woman from Jakarta alsodied from the virus after buying a live chicken from a market.
Last week, a teenager suffering from bird flu was admittedto a hospital in Jakarta.
An official at the hospital said that the teenager wasstable, but was still on a respirator to help her breathe.
Indonesia, which has now had 118 cases of the disease inhumans, has had the most number of deaths from bird flu of anycountry.
Excluding the latest case, there have been 349 cases and216 deaths from the disease globally since 2003, according toWorld Health Organization data.
