Public health informatics differs from other informatics specialties in that it
involves:
1. A focus on applications of information science and technology that promote the
health of populations, rather than of individuals;
2. A focus on disease prevention, rather than treatment;
3. A focus on preventive intervention at all vulnerable points in the causal chains
leading to disease, injury, or disability; and
4. Operation typically within a governmental, rather than a private, context.
