TUCSON - A strain of the dangerous and drug resistant bacteria known as MRSA has been confirmed at Tucson's Desert View High School.
A student is being treated for a skin infection, but Sunnyside Unified School District officials could not say when the student will return to school, said district spokeswoman Monique Soria.
Letters to parents were sent out Tuesday, the district said.
School officials were aware a student had a skin infection but they didn't know it was methicillin-resistant staphylococcus aureus, or MRSA, until Tuesday.
As a precaution, Desert View custodians began disinfecting the school's gym, locker rooms and restrooms Monday as well as classrooms the student was assigned to, Soria said.
The entire school was disinfected Tuesday, Soria said.
The school nurse also visited physical education classes to inform students of symptoms associated with MRSA and prevention measures.
The nurse also met with Desert View teachers and staff, district officials said.
Last year, several Arizona school districts reported outbreaks of the infection, including the Scottsdale Unified School District, which had five students infected at three schools.
