Pts frequently have fever, chills, sweats, cough (either nonproductive or productive of mucoid, purulent, or blood-tinged sputum), pleuritic chest pain, and dyspnea.

• Other common symptoms include nausea, vomiting, diarrhea, fatigue, headache, myalgias, and arthralgias.
• Elderly pts may present atypically, with confusion but few other manifestations.
• Physical examination often reveals tachypnea; increased or decreased tactile fremitus; dull or flat percussion reflecting consolidation and pleural fluid, respectively; crackles; bronchial breath sounds; or a pleural friction rub.
