Abstract

Norovirus is a major cause of infectious intestinal disease, and a substantial prevalence
of asymptomatic infection has been reported. We describe the prevalence, seasonality and
characteristics of asymptomatic norovirus infection in England. Healthy individuals were
recruited at random from the general population during the Study of Infectious Intestinal Disease
(1993–1996). Norovirus was identified using real-time RT–PCR. The age-adjusted prevalence
of asymptomatic norovirus infection was 12%; prevalence was highest in children aged <5 years
and showed wintertime seasonality. More work is needed to understand whether asymptomatic
infections are important for norovirus transmission leading to sporadic illness and outbreaks.
