Which family does Seneca Valley Virus belong to?

Seneca Valley Virus is a nonenveloped, positive-sense single-stranded RNA virus in the family Picornaviridae. This family is defined by small, nonenveloped virions and a genome that acts directly as mRNA to produce a single polyprotein, which is then cleaved into functional proteins. The lack of an envelope and the RNA genome organization are hallmark features that place SVV in Picornaviridae, the same group that includes poliovirus, rhinoviruses, and hepatitis A virus. The other viral families are enveloped and have different genome types and replication characteristics, so they don’t fit SVV’s profile as well. Within Picornaviridae, SVV is classified in the genus Senecavirus.
