Lymphadenopathy as a prominent, recognizable feature comes from the way plague presents when it’s in the bubonic form. The bacteria Yersinia pestis travels to regional lymph nodes and triggers intense inflammation, producing painful, swollen nodes called buboes—often in the groin, axilla, or neck. This hallmark presentation—tender regional lymphadenopathy with fever and malaise—is classically associated with plague and is a key clue in recognizing this Category A syndrome.

Botulism centers on neuroparalysis from a toxin, not swollen lymph nodes; smallpox centers on a prodrome with a distinctive vesiculopustular rash rather than lymphadenopathy; tularemia can cause regional lymphadenopathy too but is typically linked to an ulcer at the entry site and other signs, and does not have the same iconic buboes as plague. Thus the syndrome most characteristically featuring lymphadenopathy is plague.
