PRINCETON - Princeton University's Board of Trustees is meeting this weekend to address the outbreak of meningitis cases on campus.

A seventh case of meningitis was diagnosed on campus this week.

The Princeton cases are the rare Type B meningococcal bacteria. With no vaccine approved in the United States to treat the strain, the Food and Drug Administration approved importing the vaccine Bexsero, which is used in Europe and Australia.

The vaccine may be used to inoculate the university's approximately 8,000 students.

Bacterial meningitis can cause swelling in the brain and spinal cord and is spread by coughing, sneezing and kissing.
