Document Summary
Public health: the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals. Public health informatics: the systematic application of information and computer science and technology to public health practice, research and learning . 2. The final link in the surveillance chain is the application of these data to prevention and control. 3. Syndromic surveillance: surveillance using health-related data that precede diagnosis and signal a sufficient probability of a case or an outbreak to warrant further public health response. Public health surveillance is essential to understanding the health of a population. Until recent years, public health surveillance was primarily paper-based. Syndromic surveillance is part of meaningful use; therefore a basic understanding is important. Syndromic surveillance means symptoms are monitored (like diarrhea or cough) before an actual diagnosis is made.
