Human enterovirus 74 (HEV74) is a recently described serotype within the species Human enterovirus B (HEV-B). Few nucleotide sequences of HEV74 are available, and only one complete genome sequence (the prototype strain) has been published. In this study, we report the complete genome sequence of an HEV74 strain isolated from a healthy child during a stool survey in the Tibet Autonomous Region of China. The results indicated that HEV74 may be a prevalent and common enterovirus type, and that HEV74 is globally distributed, especially in Asia. Sequence analysis revealed high variability among HEV74 strains and indicated frequent recombination within HEV-B.
