Areas of viral replication vary with the genus and include the epithelium of the nasopharynx and regional lymphoid tissue, conjunctiva, and intestines (Enterovirus), the nasopharyngeal epithelium and regional lymph nodes (Rhinovirus), and the intestinal epithelium progressing to viremia with blood transport of the virus to the liver (
Hepatovirus).
Picornaviruses (family Picornaviridae) are small, non-enveloped viruses with single-stranded, positive-sense genomic RNA; they are divided into 12 genera: Aphthovirus, Avihepatovirus, Cardiovirus, Enterovirus, Erbovirus,
Hepatovirus, Parechovirus, Sapelovirus, Senecavirus, Teschovirus, Tremovirus, and Kobuvirus (1).
Picornaviruses are currently divided into 8 genera: Enterovirus, Aphthovirus, Cardiovirus,
Hepatovirus, Parechovirus, Erbovirus, Teschovirus, and Kobuvirus (1).
To the Editor: The picornaviruses constitute a large, diverse family of positive-sense RNA viruses, which comprise 8 genera: Enterovirus, Aphthovirus, Cardiovirus,
Hepatovirus, Parechovirus, Erbovirus, Kobuvirus, and Teschovirus (1).

The family Picornaviridae contains 9 genera: Enterovirus,
Hepatovirus, Rhinovirus, Kobuvirus, and Parechovirus infect humans, whereas Aphtovirus, Erbovirus, Teschovirus, and Cardiovirus are animal pathogens (1).
Within the Picornaviridae family, 5 genera are known to cause infections in humans: Enterovirus,
Hepatovirus, Rhinovirus, Kobuvirus, and Parechovirus (1).
