After two cases of meningococcal disease at the Rutgers University-New Brunswick campus in February, state and school officials have declared an outbreak of the virus on campus and are urging students to get vaccinated.

Two students on the New Brunswick campus with no link to each other became infected with the disease — one on Feb. 3 and the other on Feb. 19 — and have since recovered.

Health officials can’t predict whether there will be more cases on campus, but “having two cases occurring over a short time with genetically related organisms suggest that there is an outbreak associated with Rutgers University-New Brunswick,” a statement read on the state Department of Health website.

The Centers for Disease Control ran tests on specimens from the two February cases and found identical genes, the statement said.

No new cases have been reported since Feb. 19.

Health officials urge members of the New Brunswick campus to get vaccinated against meningitis type B.

The mandatory vaccination for on-campus students protects against types A, C, W and Y of the bacteria — but not B, which is the type involved in this outbreak, a university statement said.

Meningococcal disease is a rare infection that can be fatal if not treated immediately, according to the Rutgers health website. Early symptoms resemble the flu and include high fever, severe headache and stiff neck.

Students can get the meningitis B vaccine at the university student health centers, on-campus clinics, local health care providers or pharmacies, the university statement said.
