City Department of Health spokesman James Garrow said Tuesday the total number of probable cases stands at 67 — up from 54 cases a day before. WCAU-TV reports health officials confirmed 12 cases through laboratory testing while 55 others were listed as probable.
Probable diagnoses are used in cases where a person in the community shows mumps-like symptoms.
Health officials recommend students who may be infected limit contact with others for at least five days and seek medical care.
Mumps is a viral infection that involves swelled glands. The Centers for Disease Control and Prevention say the measles-mumps-rubella (MMR) vaccine is the best way for people to protect themselves against it.
