Gillian Rice, Graeme Garden and Alan Maryon Davis reveal how much the experts know about AIDS, and what challenges they face in finding a vaccine and a cure. With the help of specially-designed models - of the AIDS virus and of the human skin - the Bodymatters team of qualified doctors guides you through the biological facts clearly and simply so that you can decide for yourselves how likely it is that you personally will be affected by AIDS : the disease that's now killing two Britons every day.
