Astroviruses were first identified in the feces of children in 1975. Since then, they have been found in ~ 3 to 20% of children with diarrhea. Given that serological studies have demonstrated that up to 90% of children have been exposed to at least one strain of astrovirus by age 9, the prevalence of infection may be much higher. Supporting this are studies demonstrating that astroviruses can also be isolated in a subset of asymptomatic individuals, suggesting that a proportion of infected individuals shed the virus asymptomatically or for some time after the resolution of other symptoms of infection. Asymptomatic carriers may be a major reservoir for astroviruses in the environment and could contribute to dissemination of the virus.
