An understanding of public health - the systems, policies and theories that influence the health of the population - is important for decision making across the continuum of care. Introduction to Public Health provides a solid introduction to the key concepts of public health for undergraduate health science students and those new to the public health environment. The text is divided into four sections, covering an overview of public health, the impact of policy and evidence, public health strategies and contemporary issues. With contributions from a multidisciplinary range of experts, this fifth edition has been updated to include emerging public health challenges such as COVID-19, the impact of globalisation, wellbeing and chronic illnesses, as well as a clear understanding of the multidisciplinary nature of public health.Positions public health concepts within an Australian and global contextFully updated to reflect current public health policy and environmentConcise and accessible; content is chunked for easy navigationChapter case studies and examples to help illustrate key pointsReflection opportunities to deliver maximum learningWritten by experts from various public health specialties, providing a broad multidisciplinary perspectiveSuitable for undergraduate health science courses and a range of postgraduate health science courses including Graduate Certificate, Diploma and Masters in Public Health, Health Service Management and Health AdministrationAccompanied by a suite of video interviews with local experts to provide local public health contextStudent resources on Evolve: Student quizInstructor resources on Evolve: Case studies + reflection questionsVideo interviewsImage bankNew chapter about infectious diseases and COVID-19Emerging public health issues including social and emotional wellbeing especially amongst young Australians, global health and contemporary challenges facing public healthContemporary methods for planning and sustaining public health approaches
