The health ministry said the 15-year-old girl died at a Cairo hospital late Tuesday, despite being treated with the antiviral drug Tamiflu and being placed on a respirator.

The girl was hospitalized last week. Officials say none of her family members was found to have the deadly form of bird flu.

The Egyptian government and the World Health Organization say 34 Egyptians, including several children, have contracted the H5N1 form of avian flu. Fourteen of them have now died died.
