A school official (L) speaks to school security guards May 15, 2009 at Intermediate School 238 (the Susan B. Anthony School) in the Queens borough of New York where four students and one staff member have been documented with the swine flu H1N1 virus and more than 50 students have been sent home with flu-like symptoms. The New York City Health Department has recommended closing three intermediate schools in Queens for one week after documenting unusually high levels of influenza-like illness and will remain closed for at least five school days.
