CRP values can vary in ehrlichiosis, legionnaires’ disease, and rabies infection, whereas evidence on fungal coccidioidomycosis seems contrasted since low CRP values have been reported in immunocompetent cases—yet, such low values may have occurred due to the immunocompromised state [1013,1014,1015,1016,1017,1018,1019]. Here, CRP is linked to Legionnaires' disease.
