Abstract
ParechovirusA is a species in the Parechovirus genus within the Picornaviridae family that can cause severe disease in children. Relatively little is known on ParechovirusA epidemiology and pathogenesis. This review aims to explore the ParechovirusA literature and highlight the differences between ParechovirusA genotypes from a pathogenesis standpoint. In particular, the curious case of Parechovirus-A3 and the genotype-specific disease association will be discussed. Finally, a brief outlook on ParechovirusA research is provided.
