Information ⬇
- Pneumocystis is found worldwide, and most people are exposed to the organism early in life.
- Infections resulting from environmental sources and person-to-person transmission have been demonstrated; the role of airborne transmission is unclear.
- Defects in cellular and humoral immunity (e.g., due to HIV infection, malignancy, transplantation, immunosuppressive medications) predispose to Pneumocystis pneumonia (PCP). The incidence among HIV-infected pts is inversely related to the CD4+ T-cell count: ≥80% of cases occur at counts <200 cells/µL, and most cases develop at counts <100/µL.
