Indonesia laboratory test indicated a six-year-old girl tested positive for avian influenza,a director at the Health Ministry said in Jakarta yesterday.

The girl from Bekasi, a suburb of eastern Jakarta, is the 61th case of bird flu in the vast archipelago country, and of the cases,46 have died, I Nyoman Kandun told Xinhua.

"She is still alive and receiving treatment in Sulianti Suroso hospital. Her condition has improved now," Kandun said.

The H5N1 virus has been endemic in poultry in nearly all parts of Indonesia, as the number of cases has seen a steady rise in human this year.

Scare of a possible new cluster infection arose after recently a 35-year-old woman from a hamlet in West Java province died and was confirmed to have contracted the virus. A week earlier, her 9-year-old daughter was also dead after indicating bird flu signals.

Experts fear that the highly pathogenic H5N1 could mutate to a certain level that can make it transmittable among humans, which can prompt to a pandemic.
