A hospital official said a school assistant principal has become the first New York City death linked to the swine flu virus.
Flushing Hospital Medical Center spokesman Andrew Rubin said Mitchell Wiener of Intermediate School 238 died Sunday evening. Wiener had been hospitalized and on a ventilator.
New York City Health Commissioner Thomas R. Frieden issued a statement that referred to the increasing number of cases as "a rising tide of flu."
The statement continued: "With the virus spreading widely, closing these and other individual schools will make little difference in transmission throughout New York City, but we hope will help slow transmission within the individual school communities."
