A 2-year-old boy has the bird flu, the first incident of the deadly virus reported by Hong Kong public health officials in 18 months. The boy is said to be in serious condition after testing positive for the H5N1 strain, leading city officials to raise the alert level to "serious." The boy came in contact with a duck in mid-May, and developed a fever and running nose a few days later. His parents have not developed any symptoms, officials said, but are being quarantined at the same hospital where their son is being treated.
