### Patient: Hi Doctor, I have been having a fever and persistent cough for a few weeks now. Do you have any idea what could be causing this?
### Doctor: Well, based on your symptoms, you may be experiencing pulmonary fibrosis. This is a disease that causes scarring in your lungs which can cause difficulty breathing, fatigue, and a persistent cough. It's important that we conduct some tests so we can be sure of the cause of your symptoms.
