Nosocomial mumps: report of an outbreak and its control.
BACKGROUND
Mumps is a relatively uncommon disease in the United States, and nosocomial transmission of mumps is rare.


METHODS
When a recently arrived Mexican immigrant became ill with mumps in a pediatric hospital in the United States, control measures and careful secondary case surveillance were instituted. Outbreak control included isolation of the patient with symptoms, seclusion of patients potentially incubating mumps virus, and immunization of susceptible patients and health care workers.


RESULTS
A 3-year-old patient showed symptoms of mumps 18 days after onset of illness in the index patient. Two employees, a physical therapist and a nurse, became ill with mumps 20 and 28 days after the onset of illness in the index patient. No other hospital or community cases of mumps were identified.


CONCLUSIONS
Outbreak control measures were incompletely successful in stopping the spread of mumps. Preadmission immunization of all patients and mumps-specific screening and vaccination of hospital employees might be indicated in such a situation, but such measures are neither easy nor inexpensive.
