Public health informatics is the application of computer science, information and technology to the administration of public health, including disease surveillance, prevention, preparedness and health education, according to the American Medical Informatics Association.

Climate change, along with different natural and human-made health stressors, influences human health and illness in various ways. Some existing health threats will intensify and new health threats will emerge. Not everyone is equally at risk. Important considerations include age, economic resources, and location. Public health is often laid low with disruptions of physical, biological, and ecological systems, including disturbances originating here and elsewhere. The health effects of those disruptions embody increased respiratory and cardiovascular disease, injuries and premature deaths associated with extreme weather events, changes within the prevalence and geographical distribution of food- and water-borne diseases and different infectious diseases, and threats to psychological state.
