Laboratory tests revealed elevated muscle enzymes and myositis-specific autoantibodies, supporting the diagnosis. The temporal association suggests a potential post-viral autoimmune trigger, highlighting influenza B as a possible environmental factor in JDM pathogenesis. This case reinforces the need for heightened clinical awareness and further research into virus-associated autoimmune mechanisms in pediatric myopathies. application/pdf eng Wiley https://creativecommons.org/licenses/by-nc-nd/4.0/ Dans‐Caballero, S., Juan‐Cencerrado, M., Mochón‐Jiménez, C., Roldán‐Molina, R., & Pérez‐Guijo, V.
