After additional review of laboratory tests, the Centers for Disease Control and Prevention and the New Jersey Department of Health have confirmed the suspected case of measles at Princeton University. The student has recovered and is no longer infectious. Last week, Princeton’s health department required that any faculty or staff member who may have been exposed remain off campus until they submit proof of vaccination or immunity for measles. The move resulted in temporarily reduced staffing levels in some departments and offices on campus, officials said. More than 99.5 percent of the graduate and undergraduate students have been vaccinated. Princeton University staff members have contacted undergraduate and graduate students who have not been fully immunized. It is the state’s second confirmed measles case after a 1-year-old in Jersey City contracted the disease earlier this month.
