Rhinovirus Serotype 1

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 is a genus within the Picornaviridae family of viruses. There are 99 recognized types of human rhinoviruses that differ according to their surface proteins (serotypes). They are lytic in nature and are among the smallest viruses, with diameters of about 30 nanometers.
