Third U.S. Mumps Outbreak In New Jersey, Patients Were Vaccinated

| by Sarah Fruchtnicht

Eight students at the Stevens Institute of Technology in Hoboken were diagnosed with mumps this week, as New Jersey becomes the third state to see a mumps outbreak this year.

All of the students, age 18 to 21, were fully vaccinated against the mumps.

“All Stevens’ students are required to have full vaccinations before attending the University,” the college said in a statement, noting that “outbreaks of mumps have occurred in vaccinated populations before.”

The MMR – measles, mumps, rubella vaccine – given twice to children before first grade is only 88 percent effective in preventing mumps, according to the Centers for Disease Control and Prevention. It’s 99 percent effective against measles and 90 percent effective against rubella.

The CDC says more than 95 percent of people who receive a single dose of MMR develop some immunity to all three viruses.

Officials are warning those that live on or around the campus that they may have been exposed and should watch out for symptoms, which are very similar to the flu.

"At Stevens our top priority is the health and well-being of our students, faculty, and staff. Consistent with the procedures outlined by the NJDOH, all students with suspected mumps infection were isolated from others during the infectious phase of the illness and returned to their homes off campus," said Maggie Cunning, Director of the Student Health Services. "There have been no reports of newly symptomatic cases since the initial cases last week."

Officials say that infected students should make a full recovery within 10 days.

A ongoing outbreak in Ohio has seen more than 200 cases. An outbreak at New York’s Fordham University in February saw 13 cases.
