Human astroviruses (HAtVs) are positive-sense single-stranded RNA viruses that were
discovered in 1975. Astroviruses infecting other species, particularly mammalian and avian …

Astroviruses are small, non-enveloped, positive sense, single-stranded RNA viruses first
identified in 1975 in children suffering from diarrhea and then described in a wide variety of …

Group A rotavirus classification is currently based on the molecular properties of the two
outer layer proteins, VP7 and VP4, and the middle layer protein, VP6. As reassortment of all …

Recently, a classification system was proposed for rotaviruses in which all the 11 genomic
RNA segments are used (Matthijnssens et al. in J Virol 82: 3204–3219, 2008). Based on …

Acute gastroenteritis is one of the most common diseases in humans worldwide. Viruses are
recognized as important causes of this disease, particularly in children. Since the Norwalk …

Background. Although rotavirus and norovirus cause nearly 40% of severe endemic acute
gastroenteritis (AGE) in children< 5 years of age in the United States, there are limited data …

Human enteroviruses have traditionally been typed according to neutralization serotype.
This procedure is limited by the difficulty in culturing some enteroviruses, the availability of …

Human astroviruses are a leading cause of gastrointestinal disease. Since their discovery in
1975, 8 closely related serotypes have been described in humans, and more recently, two …

Our understanding of the epidemiology of astrovirus-associated gastroenteritis has changed
markedly with each improvement in detection method. In early surveys based on …

ABSTRACT A 3-year study involving 2,347 gastroenteritis samples was conducted to
determine the prevalence, time distribution, and medical significance of human astrovirus …
