Couple of clarifications: If you read carefully, Dr. Racaniello is not in any way shape or form recommending that CFS patients take anti-virals. He is talking about a scientific process by researchers designed to determine whether anti-virals are safe and effective for patients IF they prove to have a disease causing virus.
Please do not misinterpret or twist what is said.
Although not everyone is aware of it, medical science research is taking place regarding the use of anti-virals for subgroups of CFS patients who are proven to have an infectious process at work. Part of the problem is that CFS patients can and do test positive for many different viral triggers and viral combinations and anti-virals are often single virus or type of virus specific.
Or depending on location of viral loads patients can have a viral process at work that isn't found in the blood serum giving the false impression that there is no viral process at work. Not all viruses are all "lytic" all the time.
Many viruses also have tropism meaning they target specific tissues or organs. For example herpes viruses often target the neuro system.
Besides the type of virus, where it hides, and whether it is currently active (lyctic phase -
http://en.wikipedia.org/wiki/Lytic_cycle) researchers are also looking at effective dosage and side-effects which may vary with the length of the illness, co-morbid disease, viral load etc. This isn't a do it yourself weekend project.
That is also why some CFS researchers are taking a different tack and researching the effectiveness of immune modulators in this neuroimmune disease.
PS ERV should know these things, she is just indulging in confirmation bias based on her lack of familiarity with the biomedical CFS literature.
