Answer

CMV is often isolated from patients who are co-infected with other bacterial, parasitic, and fungal pathogens. In fact, CMV may be found in the lungs of approximately 75% of individuals infected by both HIV and Pneumocystis. [9] The of CMV infection in Pneumocystis pneumonia is unclear, and treatment of the latter usually leads to resolution of the pneumonia and hypoxemia, meaning that CMV treatment is not typically warranted in most cases.

For unknown reasons, CMV pneumonia without a co-infecting pathogen is uncommon.
