Public health is a field of study that focuses on promoting and protecting the health and well-being of populations, rather than individuals. It encompasses a wide range of activities, including disease prevention and control, health promotion, and environmental health. Public health professionals work to identify and address the underlying determinants of health, such as social, economic, and environmental factors, in order to improve the health of entire communities. In this abstract, we will discuss the key concepts of public health, its goals and objectives, and the challenges and opportunities facing the field today. We will also highlight the importance of public health in addressing current and emerging health issues, such as infectious diseases, chronic diseases, and environmental threats, and the role of public health in promoting health equity and social justice. Finally, we will explore some of the key strategies and approaches used in public health practice, such as epidemiology, health promotion, and policy and advocacy, and the importance of collaboration and partnerships in achieving public health goals.
