December 19, 1984 Dear David: Thanks for your newsletter. As you probably know, we have updated the summary of Retroviridae for Intervirology (a minor task), and we are anticipating some difficulty with finding a suitable name for the AIDS virus. I am waiting for the dust to settle from the nucleotide sequencing (done or almost done in four labs at least) before convening a subcommittee. But it is clear that the AIDS virus is no more related to HTLV-I than to any other retrovirus on the basis of sequence comparison. Would you like to tell Bob Gallo it shouldn't be called HTLV-III? Best regards, Harold E, Varmus, M.D.
