Holy Angels Catholic School in Aurora is closed today after being notified Wednesday of a confirmed case of MRSA at the school.
Principal Norb Rozanski said officials will not divulge whether the case involves a student or faculty member because of privacy issues.
The school is at 720 Kensington Place.
Rozanski said 57 staff members and some parents are following Kane County Health Department guidelines to make sure the school is safe by cleaning lockers and anything the 644 students may have touched.
Any clothes or items found in the students' lockers will be sent home Friday in sealed plastic bags for parents to wash.
"We are making sure and doing what we have to do for the students' safety," Rozanski said. "We don't want to lose any students. They're all special."
Methicillin-resistant staphylococcus aureus, or MRSA, is a strain of bacteria that can be found in nasal passages, skin or body secretions but does not necessarily produce the disease.
The Aurora case comes in the wake of recent reports of MRSA at two Indian Prairie Unit District 204 schools - Prairie Children Preschool and the Frontier Campus - and five reported or suspected cases at Naperville North High School.
