Legionnaire's Disease and its Mimics: A Clinical Perspective

Burke A Cunha et al. Infect Dis Clin North Am. 2017 Mar.

Abstract

Whenever the cardinal manifestations of a disorder occur in similar disorders, there is potential for a disease mimic. Legionnaire's disease has protean manifestations and has the potential to mimic or be mimicked by other community acquired pneumonias (CAPs). In CAPs caused by other than Legionella species, the more characteristic features in common with legionnaire's disease the more difficult the diagnostic conundrum. In hospitalized adults with CAP, legionnaire's disease may mimic influenza or other viral pneumonias. Of the bacterial causes of CAP, psittacosis and Q fever, but not tularemia, are frequent mimics of legionnaire's disease.

Keywords: Adenovirus; HPIV-3; Influenza like illnesses (ILIs); Mimics; Psittacosis; Q fever.
