Public Health and Policy Working Group

Health of a population determines its productivity, longevity and hence is closely related to the overall working of the state. Public health and its policies form a large chunk of volatile laws, which affect all residents. We, as the EST Working Group for Public Health and Policies, analyse and assess the role of public health in the EU, and how we can help make it more accessible and equitable.
