Human-to-Human Infection by Bird Flu Virus Is Confirmed
`An Indonesian who died after catching the A(H5N1) bird flu virus from his 10-year-old son represents the first confirmed case of human-to-human transmission of the disease, a World Health Organization investigation of an unusual family cluster has concluded, the agency said Friday.
The W.H.O. investigators also discovered that the virus had mutated slightly when the son had the disease, although not in any way that would allow the virus to pass more readily among people.’
