👉 PF-Infection, or Pulmonary Fibrosis-Induced Infection, is a condition where pre-existing pulmonary fibrosis leads to chronic lung inflammation and subsequent infection. Pulmonary fibrosis involves the scarring and thickening of lung tissue, which impairs gas exchange and creates an environment conducive to bacterial and viral colonization. This compromised lung function increases susceptibility to infections, often resulting in persistent or recurrent pneumonia. The infection can exacerbate fibrosis, creating a vicious cycle that worsens both lung health and quality of life. Treatment focuses on managing the underlying fibrosis and preventing secondary infections through antibiotics, antivirals, and supportive care.
