Artificial Intelligence (AI) is profoundly reshaping public health through its capacity for rapid, precise data analysis and predictive modelling. AI enables early detection of diseases, enhances treatment outcomes through personalised medicine and optimises healthcare resource allocation. By automating repetitive tasks and streamlining administrative processes, AI improves operational efficiency in healthcare settings, allowing healthcare professionals to focus more on patient care. Moreover, AI-driven technologies promote innovation in medical research and drug discovery, accelerating breakthroughs in treatment modalities and preventive strategies. It empowers healthcare systems to respond more effectively to public health crises and epidemics through real-time data monitoring and proactive intervention strategies. AI's impact on public health spans from enhancing disease prevention efforts to improving patient outcomes and advancing overall healthcare quality on a global scale. This book unravels the recent studies in the field of public health. It brings forth some of the most innovative concepts and elucidates the unexplored aspects of AI's impact on public health. Researchers and students in this field will be assisted by this book.
