Abstract The present study compares the risk factors, presentation and outcome of community-acquired Legionella pneumophila pneumonia in 138 sporadic-case patients (1994-2004) and 113 outbreak-case patients (2002) treated in two hospitals in Catalonia [ncbi.nlm.nih.gov]

  Clinical description LD has an incubation period of 2-10 days with fatigue and weakness often being the first signs of the disease. It manifests as pneumonia characterized by fever, cough, sputum production and shortness of breath. [orpha.net]

  A study of outbreak survivors showed persistence of fatigue (75%), neurologic symptoms (66%) and neuromuscular symptoms (63%) in months after an outbreak. See Share Your Story for a first-hand account of the severity of this disease. [legionella.org]

  A 77-year-old woman with gastric ulcer was presented to our hospital. She had an acute onset of high fever. A chest X-ray film on admission was normal, but transient bilateral pleural effusions were revealed on hospital day 7. [ncbi.nlm.nih.gov]

  Symptoms Edit Legionnaire's disease has the same symptoms as other pneumonias, which include fever, cough, fatigue, anorexia, headache, myalgia and even diarrhea. The average incubation time is between two and ten days. [house.wikia.com]

  Other symptoms may include a high fever, chills, myalgia, muscle aches, and/or headache. Abdominal pain, nausea, vomiting, and diarrhea are also common, and some people may have confusion or other mental changes. [dshs.state.tx.us]

• Distractibility

  A further issue is that people with legionellosis can present with a wide range of symptoms, some of which (such as diarrhea) may distract clinicians from making a correct diagnosis. [en.wikipedia.org]

• Headache

  Pontiac fever may also include fever, headaches, and muscle aches, but tends to have a shorter duration — usually two to five days — and symptoms do not include pneumonia. [epi.publichealth.nc.gov]

Other studied outcomes were not significantly different among treatment groups. CONCLUSIONS: Few clinical data on legionellosis treatment are available. [ncbi.nlm.nih.gov]

Management and treatment Treatment involves antibiotics (usually macrolides and quinolones). Hospitalization is often required. Ventilatory support may be necessary in those with serious breathing difficulties. [orpha.net]

Prognosis In most cases, LD is treated and cured with antibiotics but in those with compromised immune systems or underlying health conditions the prognosis can be poor. The overall case fatality rate is around 10-15%. [orpha.net]

Both had serologic confirmation of legionellosis by indirect fluorescent antibody assay for Legionella pneumophila without seroconversion for Mycoplasma pneumoniae, and Chlamydia pneumoniae, and had a good prognosis. [ncbi.nlm.nih.gov]

The most common etiologic agents were Legionella pneumophila (58.5%) and Legionella feeleii (39.4%), the latter being responsible for only one large outbreak of PF. [ncbi.nlm.nih.gov]

Etiology LD is caused by Legionella pneumophila (most commonly serogroup 1), a bacteria found in water and wet soil. [orpha.net]
