Single Base Substitutions in the Capsid Region of the Norovirus Genome during Viral Shedding in Cases of Infection in Areas Where Norovirus Infection Is Endemic obara2008single

This study investigates the duration of norovirus RNA shedding in two food handlers-one symptomatic and one asymptomatic-using repeated real-time reverse transcription-PCR tests on fecal specimens. Norovirus RNA was detected and quantified over time, and the duration of viral shedding was compared between symptomatic and asymptomatic individuals.
