Yes, we've heard all about the DNA-altering vampire retrovirus as well
as vampiric symbionts from across "the veil." Unfortunately, the
originators of both of these theories, convincing as they may sound, are
attempting to pass off their theories as "truths". Theories presented to
alt.vampyres as "fact" or "truth" will probably be scrutinized,
challenged, and referred to experts. To whit:
Following is a letter I received from Jon Martin, Ph.D., Associate
Professor for Virology at Mercer University School of Medicine.
Dr. Martin explains the current status of human retroviruses:
"...Personally, I think the retrovirus as an explanation is a
clever notion ... but nothing more than that. There are only three
retroviruses known to infect the human. One of them is HIV, which
causes AIDS. A second one causes an uncommon leukemia (human T-cell
leukemia/lymphoma virus; HTLV), and the third is not yet clearly
associated with human disease (but is related to HTLV)."
