Answer

HHV 6 (A and B) and HHV 7 have a limited clinical significance and prevalence as lung pathogens. HHV 6 appears in healthy individuals or HIV-infected patients with a high CD4+ count, in whom it may result in further immunosuppression. HHV 8 is an important pathogen in HIV patients with a 200 CD4+ count of less than 200 cells/µL and has been associated with Kaposi sarcoma in the lungs, sometimes with alveolar hemorrhage.
