Chapter 4.3 Complications of pneumonia

Septicaemia is the most common pneumonia complication and occurs when the bacteria causing pneumonia spreads into the bloodstream (see section 6.5). The spread of bacteria can lead to septic shock or metastatic secondary infections like meningitis especially in infants, peritonitis, and endocarditis especially in patients with vulvar heart disease or septic arthritis. Other common complication include pleural effusion, empyema and lung abscess.
