Temporal Clustering of Mycoplasma pneumoniae-Associated Encephalitis and Stroke, South Korea, 2024.
Seventeen pediatric encephalitis (n = 12) or stroke (n = 5) cases clustered temporally during the 2023-2024 Mycoplasma pneumoniae epidemic in South Korea; similar patterns had not been noted in previous seasons. Those findings might reflect postpandemic changes in clinical manifestation and underscore the need for neurologic surveillance during M. pneumoniae epidemics.
