WESTFORD, Mass. — A Massachusetts high school is being disinfected after several students were diagnosed with the staph infection known as MRSA.

The superintendent confirmed to The Sun of Lowell on Wednesday that four Westford Academy students have MRSA, which stands for methicillin resistant staphylococcus aureus.

Superintendent Everett Olsen says students were previously scheduled to have no school Thursday, so crews will spend the day disinfecting, paying particular attention locker rooms and physical education equipment.

The administration is urging students to wash their clothes and gym uniforms and to wash their hands often.

MRSA is a bacterial infection that can cause skin infections, pneumonia and bloodstream infections. It can be spread by coming into contact with personal items or surfaces exposed to the bacteria. It is resistant to some commonly used antibiotics.
