Abstract
Aichi virus (AiV), genus Kobuvirus, family Picornaviridae, is associated with gastroenteritis in humans. Previous studies have shown high seroprevalence but low incidence (0.9-4.1%) in clinical samples. We report here the first detection of AiV in Sweden. Two hundred twenty-one specimens from hospitalized patients with diarrhea, who were negative for other enteric viruses, were included in the study. AiV were detected in three specimens, all from elderly patients. Phylogenetic analysis revealed that the three Swedish isolates belonged to genotype A and were genetically closest to European and Asian strains of AiV.
