RESPIRATORY SYSTEM INFLAMMATION



In general

  • Some viruses are thought to induce modifications of the pulmonary defences by:
    • Damaging the upper respiratory tract, thereby facilitating bacterial attachment and colonisation, with reduced mucociliary clearance
    • Decreasing surfactant levels by destroying Type 2 pneumonocytes
    • Impairing the phagocytic ability of alveolar macrophages
