Lab Confirms Bird Flu in Four More Humans

A Hong Kong laboratory recognized by the World Health Organization has confirmed four more human bird flu cases in Indonesia, including two deaths, a senior Indonesian Health Ministry official said.

Hariadi Wibisono, the ministry's director of control of animal-borne diseases, said that raised Indonesia's confirmed human bird flu cases to 23.

Although the H5N1 strain of avian flu mostly affects birds, it has infected 161 people and killed 86 of them since 2003, according to the WHO.
