Everyone's immune system can deal with any virus if it is given the means to do so... (This means getting your blood in an alkaline state and eliminating crap like simple sugars and toxic chemicals added to our food supply such as asparatame, chlorine, and MSG) Don't EVER believe the hype from pharmacutical companies that say these viruses are always "with you for life". Total rubbish.
Think about this: How many times have you had a cold in your life? Surely everytime you get a new cold it is not the same "old" cold virus returning that is still dormant in your system but a new strain. Have you ever had a wart on your hand or foot when you were a kid that NEVER returned? Your telling me this HPV virus is "still dormant"?? Come on.
Anyone who has the exact same re-occuring virus needs to clean up their body as much as possible from all toxins and let their immune system do its job. Yes, some are more stubborn than others (such as herpes viruses) and may require additional assistance in the form of supplements but they are not impossible for your immune system to find and destroy.
