Patients can develop two clinical phases: an acute septic phase and a chronic eruptive phase associated with skin lesions. [3] In the acute phase (also known as Oroya fever or fiebre de la Oroya), B. bacilliformis infection is a sudden, potentially life-threatening infection associated with high fever and decreased levels of circulating red blood cells (i.e., hemolytic anemia) and transient ...
