When did the correct spelling of this virus change from AIDS to Aids?
It's probably when we gave up control to word processing programs on capitalization. The name for the virus is HIV, Human Immunodeficiency Virus. Some deniers don't believe that virus causes AIDS, Acquired Immune Deficiency Syndrome. I do. IMHO, there's a ton of literature that HIV causes AIDS. You can find a bunch of threads posted by me using the keyword hivaids.
