Ooops. Sorry for the bad wording. That should read "someone" not "something". Anyway, I ran a Medline search and find that most work was done in the 60's and 70's. I found nothing in the 90's so don't know who to contact for questions. Is Yaba virus called something else now? Thanks for the help, Janette Wallis, Ph.D. janette-wallis at uokhsc.edu
