The Health Ministry said the girl, from the West Java district of Karawang, died Tuesday in a Jakarta hospital that had treated her since June 28.
She first developed a fever June 18, one day before going on holiday to Singapore, where a doctor diagnosed her with laryngitis, the ministry said Friday on its website. She returned five days later and was treated at a Karawang hospital before being transferred to Jakarta.
The ministry says the girl might have had contact with slaughtered chickens she and her father bought from a local market.
Bird flu has killed more than 350 people worldwide. Indonesia accounts for 158 of the deaths.
