in critical condition

While most human bird flu cases have been mild, a Canadian teen infected with the virus last month was hospitalized in critical condition after developing a severe lung infection.

One of the other two injured people was listed in critical condition, and the other was said to be stable.

Six others were also taken to a hospital — two of them in critical condition, the other four with non-life threatening injuries, said Los Angeles Fire Department spokesperson Margaret Stewart.

The second is a Canadian teenager who has remained hospitalized in critical condition with bird flu, again with unknown exposure and stark in its severity.

In British Columbia, a teenager is in critical condition with the disease.
