Which bug is associated with post-influenza pneumonia, lung abscess, and empyema?

• A. Streptococcus pneumoniae
• B. Haemophilus influenzae
• C. Staphylococcus aureus
• D. Pseudomonas aeruginosa

Answer: (C)

After influenza, the lung is susceptible to secondary bacterial infection, and Staphylococcus aureus is classically associated with this post-viral pneumonia. It has a knack for causing rapid, necrotizing infection of lung tissue, which can lead to lung abscess formation and spread into the pleural space, resulting in empyema. While other bacteria like Streptococcus pneumoniae or Haemophilus influenzae can cause pneumonia, they are not as characteristically linked to necrosis, abscess, and empyema after influenza. Pseudomonas is more typical in hospital-related settings or with certain chronic lung conditions, not the classic post-influenza scenario.
