Mentor High School was told Tuesday night that one of its students was diagnosed with an MRSA staph infection.

According to a release on the school's website, the custodial staff immediately cleaned and disinfected every room in which the girl had class, as well as common areas like the gym and bathrooms.

"School administrators were told the student’s infection was covered while she was at school. This student is not involved in any extracurricular activities," the school said in the release.

When asked how the student was, the district's Director of Community Relations Kristen Kirby said, "We've been told she is doing fine."

The student has not returned to school yet and must be cleared by a doctor first.

Methicillin-resistant Staphylococcus aureus, or MRSA, is an antibiotic-resistant form of staph that spreads from skin-to-skin contact or direct contact with somewhere the bacteria lives. This can include towels, razors and clothing.
