Kentucky ? An eastern Kentucky school district with one confirmed case of antibiotic-resistant staph infection plans to shut down all 23 of its schools Monday, affecting about 10,300 students, to disinfect the facilities.

The project will involve disinfecting classrooms, restrooms, cafeterias, hallways, locker rooms, buses and even external areas such as playgrounds and sports fields, said Roger Wagner, superintendent of Pike County schools.

“We’re not closing schools because there’s been a large number of breakouts, but as a preventive measure,” Wagner said.

One Pike County student was diagnosed in September with MRSA, or methicillin-resistant Staphylococcus aureus. The bacterial strain can be treated with other antibiotics, but without treatment it can be deadly.

The bacteria was blamed for the death of a 17-year-old Virginia high school senior and a 12-year-old New York City middle school student this month. At least seven students on New York’s Long Island were recently diagnosed with MRSA, as were 10 members of an athletic team at Iona College in New Rochelle, N.Y. However, a government report has estimated it may sicken more than 90,000 Americans each year.
