The incidence rate for scarlet fever in South Korea is rising. During 2008-2015, 
we collected group A Streptococcus isolates and performed emm and exotoxin 
genotyping and disk-diffusion antimicrobial tests. Scarlet fever in South Korea 
was most closely associated with emm types emm4, emm28, emm1, and emm3. In 2015, 
tetracycline resistance started increasing.
