State-run Egyptian reports that a four-year-old Egyptian boy has tested positive for the deadly H5N1 bird flu virus.

MENA news agency Saturday quoted a health ministry statement that identifies the boy as a resident of the Upper Egypt province of Qena.

The World Health Organization has not yet confirmed the case.

As of mid-June, the WHO had confirmed 36 human cases of H5N1 in Egypt. The nation's last confirmed infection involved a four-year-old girl, also from Qena.

Earlier Saturday, Indonesian health officials said a three-year-old Indonesian girl is being treated on Sumatra Island for bird flu.

Officials said the girl's condition has improved since she was admitted to a hospital in Pekanbaru.

People generally contract the deadly virus from sick or dead poultry, but scientists fear the virus could mutate into a form easily passed between humans.

Bird flu has hit Indonesia harder than any other nation. Eighty Indonesians have died from the disease.

Indonesia has agreed to work with a U.S. firm to develop a vaccine for the disease.
