CMV pneumonia is considered the most common life-threatening complication of bone marrow transplantation (BMT) and solid-organ transplantation.

The rate of CMV pneumonia in BMT recipients is 10-50%, as reported in different studies. In patients receiving solid-organ transplants, CMV reactivation is reported in as many 70% of patients, but only 20% develop clinically significant infections. Studies of CMV pneumonia in BMT recipients demonstrate a 31% mortality rate in treated patients and a decrease from previously reported rates of 56-100% in untreated patients. The mortality rate is reportedly 75% in untreated immunosuppressed persons. [56]
