Figure 2

Annual trends in pediatric Mycoplasma pneumoniae–associated admissions and central nervous system complications in South Korea. A) Data obtained from 3 hospitals during 2011–2024. Bars represent ischemic stroke and encephalitis cases per 10,000 pediatric hospitalizations. Data line indicates annual M. pneumoniae–associated pediatric admissions per 1,000 hospitalizations. B) National data from 2015–2021. Bars show annual pediatric stroke and all-age encephalitis cases. Data lines represent M. pneumoniae–associated hospitalizations in pediatric and all-age populations reported to the Korea Disease Control and Prevention Agency sentinel surveillance system. All values in panel B are presented on a 1/100 scale. A, all age; P, pediatric. Scales for the y-axes differ substantially to underscore patterns but do not permit direct comparisons.
