Enteroviruses are small viruses that are made of ribonucleic acid (RNA) and protein. Enteroviruses belong to the Picornaviridae family of viruses and are divided into 5 groups with many types within each group, including polioviruses (3 types), coxsackieviruses A (23 types), coxsackieviruses B (6 types), echoviruses (33 types), and other enteroviruses (4 types).
Over the last several months, the United States has experienced a nationwide outbreak of enterovirus D68 (EV-D68) associated with severe respiratory illness. Further information on outbreak is available on the CDC website.
