Case history

Case history

A 15-year-old boy presents with a 2-week history of headache and non-productive cough. On physical examination he is a well-developed but sick-looking young man in mild respiratory distress. His temperature is 38.8°C (101.8°F) and his respiratory rate is 22 breaths per minute. Auscultation of the chest reveals scattered crackles and wheezes over both lungs with dullness at the right base.

Other presentations

Although Chlamydia pneumoniae classically causes community-acquired pneumonia, many respiratory infections due to C pneumoniae are subclinical or asymptomatic.[3] Clinically, community-acquired pneumonia due to C pneumoniae cannot be differentiated from pneumonia due to other organisms, especially Mycoplasma pneumoniae. C pneumoniae has also been associated with acute bronchitis and exacerbations of reactive airway disease. The association of C pneumoniae with upper respiratory tract infections including pharyngitis, sinusitis, and otitis media is less clear.
