Seven Strains of Enterovirus D68 Detected in the United States during the 2014 Severe Respiratory Disease Outbreak

Clusters of severe respiratory disease in the United States were reported to the CDC beginning in August 2014. Enterovirus D68 (EV-D68) was identified from 83% (30/36) of initial severe cases. Investigations in August and September found severe EV-D68 cases to be widespread across the United States. We report seven EV-D68 genomes from the outbreak.
