(AP) - New York City's health commissioner says two more deaths have been linked to the swine flu.
Dr. Thomas Frieden said Tuesday a 41-year-old woman from Queens and a 34-year-old man from Brooklyn have died - for a total of four since the outbreak started last month.
Earlier on Tuesday, 20 city schools reopened a week after an assistant principal died.
The schools include Intermediate School 238 in Hollis, Queens, where assistant principal Mitchell Wiener became the city's first death from the virus.
Over the weekend, a woman in her 50s died, becoming the city's second swine flu victim and the nation's 11th.
