Thanks a lot for all the info it makes sense and so happy you found something to help! I feel I am also the viral subtype as I was tested positive for the active form of CMV 2 months after the onset of my CFS. I had blood work to show my antibodies to CMV is still very high recently, but not "active." Sorry can i ask around what percentage of well you were initially before starting the tenofovir?
Id be skeptical that high cmv wasnt active. If you have high or low neutrophils or lymphocytes or white blood cell counts id say its quite possible cmv is active.
Maybe worth trying antiviral for it???
