Epidemiologists can be seen as medical detectives who try to research and determine the causes of illnesses and disease. Thanks to the work of epidemiologists, public health policies are made and disease management strategies are planned all across the world. In essence, an epidemiologist tries to find out how and why do illnesses and diseases appear, how they spread and what can be done to prevent them from spreading and reoccurring.
