Long Island school officials have confirmed a student has been infected with the potentially dangerous MRSA bacteria.
The Hauppauge student's condition was not disclosed.
In February, a Hauppauge high school wrestling star became seriously ill from MRSA.
School officials tell Newsday they're sanitizing instructional areas. Students are being reminded about proper hygiene. They should consult a doctor if they suspect a MRSA infection.
MRSA is a strain of staph bacteria that's resistant to common antibiotics.
Most infections result in minor skin irritation. But it can be life-threatening if it enters the bloodstream through an open wound.
Nationally, the U.S. Centers for Disease Control and Prevention reported 89,785 cases of invasive MRSA and 15,249 deaths in 2008.
