Public health surveillance (PHS) is critical to efficient and effective disease prevention and control. Public health professionals must have information about the parameters of disease occurrence to develop and maintain prevention and control programs. Transforming Public Health Surveillance (TPHS) provides a thorough review of PHS history, purposes, uses, elements, data sources, models, analyses, actions, preparation of reports, evaluation, and ethical and legal issues. Discussions embrace both infectious and non-communicable diseases. And it helps students recognize the importance of a direct association between PHS and public health action and to become familiar with the use of information, communication, and technologies (ICT). TPHS teaches concepts from both developed and developing countries and introduces lessons learned in international health crises to construct a framework to provide an efficient, effective, and equitable global prevention, detection, and response.
