BLOOMINGTON, Ind. (AP) — Health officials say the number of confirmed cases of mumps at Indiana University in Bloomington has reached 20 since Feb. 12.

Dr. Beth Rupp of the Indiana University Health Center said during a news conference Monday that she learned of the 20th case just moments earlier. Among the first 19 cases, Rupp said 16 students have recovered while three remain in isolation. None have reported any major medical complications.

Rupp says there are at least three pending cases and more testing needed among students who have either shown symptoms or had contact with a confirmed case.

She says most of the sick students had been vaccinated against the virus.

At Temple University in Philadelphia, health officials says they’ve had more than 100 confirmed or probable cases of mumps.
