Rhinoviruses (from the Greek (gen.) "nose") are the most common viral infectious agents in humans and are the predominant cause of the
common cold. Rhinovirus infection proliferates in temperatures between 33–35 °C (91–95 °F), the temperatures found in the nose. Rhinoviruses comprise three species in the genus
Enterovirus of the
Picornaviridae family of
viruses.
