Beaufort County schools now say five students have come down with an antibiotic resistant staph infection, also known as MRSA.
Doctors have cleared two of the students to return to school and sports.
Four of the cases are students from Northside High School. One of them is from John Small School, which houses 4th and 5th graders.
Officials say schools with cases are continuing to clean and sanitize as advised by the health department. It takes direct contact - skin to skin - for transmission of this infection.
