Important Information:
HHV-7 is detectable in a variety of transplant settings, both HSCT and solid organ. Direct effects of HHV-7 include fever, rash, myelosuppression, encephalitis, and pneumonitis. Potentially more important are the indirect effects HHV-7 has on CMV disease, invasive fungal disease, and allograft dysfunction. Quantitative HHV-7 DNA PCR can be used to document the presence of the virus as well as track the course of infection.
