This online resource explores the ongoing battle between people and both communicable and non-communicable diseases. Throughout history people have looked for ways to treat or cure those diseases. For centuries we had little or no idea what causes disease, and so our attempts to find medicines were limited. Today our knowledge of the processes of disease is growing all the time - and with it, our understanding of which medicines to use and how they work. This resource explores how medicines and vaccination are currently used to tack a range of communicable and non-communicable illnesses including heart disease and cancer.
