Scarlet fever(SF)is a common infectious disease caused by group A streptococcus(GAS)[1].During the 18th and 19th centuries,SF was a significant cause of mortality in children aged 5-15 years worldwide[2].The incidence and fatality rates of SF have decreased remarkably due to the widespread use of effective antibiotics and improvements in diet and sanitation[3].However,the recent resurgence of SF has sparked significant interest in infectious diseases[1,3].Given the insufficient understanding of the triggers that cause SF outbreaks and the absence of available vaccines to prevent GAS infection to date[1],effective prevention and control programs are needed to manage the ongoing spread of SF.
