Detection of RNA of Mumps Virus during an Outbreak in a Population with a High Level of Measles, Mumps, and Rubella Vaccine Coverage

Abstract

The duration of mumps virus RNA detection was studied during a mumps outbreak in a highly vaccinated university population. Seven of the eight reverse transcription-PCR-positive specimens were collected during the first 3 days of parotitis, suggesting that viral shedding is minimal after the first 3 days of symptoms.
