The hyper-virulent emm59 genotype of invasive group A Streptococcus was identified in northern Arizona in 2015.
Eighteen isolates belonging to a genomic cluster grouped most closely with recently identified isolates in New Mexico.
The continued transmission of emm59 in the southwestern United States poses a public health concern.
