Hello - it is classified as a virus at this point BUT - I have seen HUMAWORM clear up shingles. There are lots of things that I believe are misclassified. They have released the "new" information that cervical cancer is caused by the HPV - (human paperiloiois (can't spell it) virus). They also now know helicobacter pylori (spelled correctly!)is responsible for peptic ulcers. HUMAWORM kills that too.
