Objective:

To detail the clinical trajectory and successful management of scrub typhus-associated HLH in a child, highlighting key diagnostic clues.

Approach:
    Key Findings:
    • Rapid decline in platelets/fibrinogen and sharp rise in ferritin/LDH should alert clinicians to possible HLH.
    • Early combined therapy targeting both the infection and cytokine storm may lead to favorable outcomes.
    Interpretation:

    This case underscores the importance of recognizing HLH in pediatric scrub typhus and the effectiveness of early intervention.

    Limitations:
    • Single case report limits generalizability.
    • Further studies needed to confirm findings and treatment efficacy.
    Conclusion:

    Early diagnosis and combined therapy are crucial for managing HLH associated with scrub typhus in children.
