Four students have contracted viral meningitis at Pitman High School.
The virus is not considered as dangerous as bacterial meningitis. But it can cause fever, headaches and nausea.
The Gloucester County Health Department is working with school officials to prevent the spread.
Nursing director Ditty Mae Jankauskas tells NJ.com students should not share water bottles or eating utensils.
Officials are urging students and teachers to wash their hands and frequently touched surfaces are being cleaned.
