I was honored to present the Keynote Address at the XXII meeting of the Brazilian Virology Society on 23 October 2011. In my talk entitled "The World of Viruses", given to an audience of 640 virologists, I shared my enthusiasm for these amazing microbes by discussing ten seminal virologists and ten compelling virology stories of recent years. I think you will like it whether or not you are a scientist. This video is slightly different from a previously uploaded version in that I added a photo of the audience that I took at the start of my talk.
