Parvovirus

Parvovirus, sometimes truncated to "parvo", is both the common name in English casually applied to all the viruses in the Parvoviridae taxonomic family and also the taxonomic name of the Parvovirus genus within the Parvoviridae family. This creates a confusion of terms, because parvoviruses which causes human and animal diseases are not in the genus Parvovirus, though they are casually called parvoviruses. Parvoviruses are typically linear, non-segmented single-stranded DNA viruses, with an average genome size of 5000 nucleotides. Parvoviruses are some of the smallest viruses (hence the name, from Latin parvus meaning small) and are 18–26 nm in diameter.
