Meningococcal disease is a potentially life-threatening bacterial infection that can lead to meningococcal meningitis, an inflammation of the membranes surrounding the brain and spinal cord, or meningococcal septicemia, an infection of the blood. Adolescents and young adults account for nearly 30 percent of all cases of meningitis in the United States. In addition, approximately 100 to 125 cases of meningococcal disease occur on college campuses each year, usually among students in residential halls. Evidence shows that approximately 70 to 80 percent of cases in the college-age group are caused by serogroup C, Y, or W-135, which are potentially vaccine-preventable.
