According to federal health officials, the strain of meningitis that has plagued the Princeton University campus is also responsible for the death of a Drexel University student. Stephanie Ross, 19, died earlier in March after becoming infected with meningitis B, a rare bacterial infection that has infected eight students at Princeton University.

The Centers for Disease Control and Prevention noted that the findings suggest that this particular strain of meningitis is still present and active at Princeton University.

Ross was brought to Penn Presbyterian Medical Center after being found unresponsive in her sorority house on March 10, according to philly.com. She died at the hospital.

CDC researchers found that Ross had been in contact with students at Princeton University a week before she became ill.

The meningitis outbreak at Princeton led to a vaccination campaign at the school using a vaccine that was unlicensed and had been imported because the typical meningitis vaccine does not protect against the strain.

The CDC said in a statement, “CDC’s laboratory analysis shows that the strain in Princeton University’s serogroup B meningococcal disease outbreak matches the strain in the Drexel University case by ‘genetic fingerprinting.'” The statement continued, “This information suggests that the outbreak strain may still be present in the Princeton University community and we need to be vigilant for additional cases.”

Dr. Thomas Clark of the CDC notes that the Drexel University case does not signify a new outbreak at Drexel.

Both CDC and state health officials have been tracking everyone who came into close contact with Ross.

The CDC said that there have been no new cases of meningitis B at Princeton University since December 9, 2013, although it doesn’t mean that a person could not have been infected. According to the report, “Available data show most adolescents that get two doses of this vaccine are protected from getting meningococcal disease. However, vaccinated individuals may still be able to carry the bacteria in their throats, which could affect others through close contact.”
