The clinical presentation of both the adult and pediatric patient with<unk>  depends upon several factors, including the causative micro-organism. Most cases present themselves in the setting of a pneumonia, although up to one third of patients do not have clinical signs of pneumonia and as many as 25% of cases are associated with trauma (including surgery). Symptoms include fever, dry cough, sweating, difficulty breathing, and unintentional weight loss. The elderly often do not have classic symptoms, but instead have anemia and exhaustion.
