Has anyone heard of this very dangerous infection of the lungs? It is most often found in AIDS or Leukemia patients using chemotherapy. They say it kills tens of thousands annually, is hard to diagnose, takes six to nine months to resolve. I am just learning about it, before I see my pulmonologist. It is hard to detect as it masks itself as other diseases. Common symptoms - coughing, shortness of breath, wheezing, fatigue and weakness/achiness. The most common tests for it are an injection of the disease under the surface of the skin or a sample of sputum.
