NEW YORK - New York City has closed three schools in response to a swine flu outbreak that has left an assistant principal in critical condition and sent hundreds of pupils home with flu symptoms, in a flare-up of the virus that sent shock waves through the world last month.
Mayor Michael Bloomberg said that four pupils and the assistant principal have documented cases of swine flu at a Queens middle school. More than 50 pupils have gone home sick with flulike symptoms there, he said. At another middle school in Queens, 241 students were absent yesterday. Dozens more were sick at an elementary school.
