What are all the viruses people are being tested for in order to see if antivirals might help them? Do regular infectious disease docs who are not CFS specialists give antivirals to CFS patients? Is there a big difference between the various antivirals people talk about on here, Valtex, Vlacyte, Famvir, etc or are they all basically the same? Or do they address different types of viruses? Are there significant side effects/risks? I have no idea about any of this stuff, but want to get more acquainted so I can discuss with a doctor. Thanks.
