At the University of Missouri, the Student Health Center has now put the number of confirmed cases at 31 lab-confirmed cases of mumps and an additional 27 probable cases. This is up from 17 confirmed cases one week ago.

A probable case is defined as a person with at least two days of mumps-like symptoms and epidemiologically linked to a confirmed case. This means the patient has been in close contact with someone with confirmed mumps.

Officials at the State University of New York (SUNY) at New Paltz have recorded an additional confirmed case, bringing the total to 16 cases.

The Boston Globe reported Wednesday that Tufts University is encouraging students to take precautionary measures after nine students were diagnosed with mumps.

All nine cases have been diagnosed over the past three weeks on the school’s Medford campus, according to Patrick Collins, a Tufts spokesman.
