Pi·cor·na·vir·i·dae

(pī-kōr'nă-vir'i-dē),

A family of very small (20-30 nm) ether-resistant, nonenveloped viruses having a core of positive sense single-stranded infectious RNA enclosed in a capsid of icosahedral symmetry with 60 capsomeres. Numerous species (including the polioviruses, coxsackieviruses, and echoviruses) are included in the family. There are five accepted genera: Enterovirus, Rhinovirus, Hepatovirus, Cardiovirus, and Aphthovirus.

Human parechovirus (HPeV) is a newly classified genus ("Parechovirus") that was previously classified as enterovirus within the family Picornaviridae. Detectable by specific (i.e., not enteroviral) real-time reverse-transcription polymerase chain reaction (RT-PCR) assay, HPeV has been associated with sepsislike illness and meningitis, particularly in young infants.
