The Hep B story is a visual, interactive app in both English and Yolŋu matha designed for patients living with chronic hepatitis B and their families. It tells the story of the Hep B virus, how you get it, what happens over time, how you know you have it, as well as details about immunisation and treatment (including game). There is also a separate women’s section dealing with mother to child transmission and ways to prevent it. It was produced in conjunction with Yolŋu people who are Indigenous Australians living in northern Australia and is grounded in Yolŋu culture, worldview and language.
