• Mumps is presumed to confer permanent immunity. Three patients previously known to possess mumps serum antibodies subsequently developed clinical parotitis and showed a diagnostic fourfold rise in mumps V antibody.
A review of the literature disclosed several cases of parotitis, either recurrent or postimmunization, but the preparotitis immune status of the patient was unknown or the cause of the mumps was not verified. Case reports of parotitis due to parainfluenza 3 and coxsackie viruses A and the heterotypic serological responses among the myxoviruses are reviewed.
Parotitis, especially after prior immunization, requires definitive diagnosis by viral isolation and/or serology before it can be attributed to mumps virus.
