Gastroenteritis and the novel picornaviruses aichi virus, cosavirus, saffold virus, and salivirus in young children

The newly discovered human picornaviruses aichi virus, saffold virus, and salivirus are circulating in Danish children, with the most common being saffold virus. Saffold virus was seen almost exclusively in the autumn and winter period. Salivirus was the only virus, which was significantly associated with gastroenteritis, although the number of positive samples was rather low.
