unreferenced date November 2010 Tele epidemiology is a methodological and application area of epidemiology concerned with the application of space based system s communication , Earth observation , positioning system s, Geographical Information Systems , biostatistics , etc. in the study of the space and time distribution of health events or disease process in population s. In this broader sense, the term includes applications of all space based systems to the field of epidemiology. The use of a satellite communication system to support the investigation of an infectious disease outbreak , the use of a remote sensing satellite to recognize and locate physical features on Earth for example, an industry industrial plant suspected of a point source contamination of air or water or non visible characteristics of a land area for example, calculation of the NDVI index in relation to the distribution of species of mosquito es to assess health risk in surrounding populations, or the use of global positioning satellites GPS to track the migration of animals to better understand possible route of malaria transmission are all illustrations of tele epidemiology. By recent usage, the term often designates the cross disciplinary area linking specifically the applications of satellite technologies for earth observations remote sensing to epidemiological research, health surveillance , and field support during health emergency response . In this restricted sense, the area of tele epidemiology is closely related to the domain of landscapeepidemiology .

E epidemiology is the science underlying the acquisition, maintenance and application of Epidemiology epidemiological knowledge and information using digital media such as the internet , mobile phones , digital paper , digital TV . E epidemiology also refers to the large scale epidemiological studies that are increasingly conducted through distributed global collaborations enabled by the Internet. The traditional approach in performing epidemiological trials by using paper questionnaires is both costly and time consuming. The questionnaires have to be transformed to analyzable data and a large number of personnel are needed throughout the procedure. Modern communication tools, such as the web, cell phones and other current and future communication devices, allow rapidly and cost efficient assembly of data on determinants for lifestyle and health for broad segments of the population. Modern IT technology provides means for storage, organization and retrieval of large amounts of biological and lifestyle data, which will ensure more data and more reliable statistical results. Efficient number crunching computing, using modern analytical tools and simulation based inference procedures allow knowledge to be extracted from the resulting large and complex data structures. Web portals directly connected to the studies enables instant feedback and information to the participants. It also allows animations and other web based tools linked to the questionnaires, which can increase the interactivity and facilitates flow of information between the study participant and the study centre.

NOTOC Environmental epidemiology is the branch of epidemiology concerned with discovery of the environmental exposures that contribute to or protect against injuries, illnesses, developmental conditions, disabilities, and deaths and identification of public health and health care actions to avoid, prepare for, and effectively manage the risks associated with harmful exposures. Environmental epidemiology studies external factors that affect the incidence, prevalence, and geographic range of health conditions. These factors may be naturally occurring or may be introduced into environments where people live, work, and play. Environmental exposures are involuntary and thus generally exclude occupational exposures and voluntary exposures such as active smoking, medications, and diet. Environmental exposures can be broadly categorized into those that are proximate e.g. directly leading to a health condition , including chemicals, physical agents, and microbiological pathogens, and those that are more distal, such as social conditions, climate change, and other broad scale environmental changes. Proximate exposures occur through air, food, water, and dermal contact. Distal exposures cause adverse health conditions directly by altering proximate exposures, and indirectly through changes in ecosystems and other support systems for human health.

The emerging field of conflict epidemiology offers a more accurate method to measure deaths caused during violent conflicts or wars that can generate more reliable numbers than before to guide decision makers. In February 2001 the Carter Center and the United States Institute of Peace USIP , in collaboration with CARE relief , Emory University and the Centers for Disease Control and Prevention CDC , sponsored a meeting on Violence and Health . The goals of the meeting were to determine the impact of violent conflict on public health and to advise public health training programs on means to enhance the work of public health professionals in working in violent conflicts. Compiling or estimating the numbers of deaths caused during wars and other violent conflicts is a controversial subject. Historians often put forward many different estimates of the numbers killed during historic conflicts. What conflict epidemiology offers is a better methodology to more accurately estimate actual mortality rates during existing wars and conflict. Iraq Conflict 2003 The subject of conflict epidemiology made headline news after a report of a survey was conducted by an American and Iraqi team of public health researchers. Data were collected by local Iraqi doctors and analysed by the faculty of the Johns Hopkins School of Public Health .

Psychiatric epidemiology is a field which seeks to study the conceptualization, etiology , and prevalence of mental illness in society. It is a subfield of the more general epidemiology . It is very difficult to accurately study mental illness conceptualization, etiology, and prevalence, and current techniques are relatively poor. Two areas of concern, sometimes called the crisis of psychiatric epidemiology today, are the high estimates of mental illness that many studies produce and the difference in results between studies. How studies are conducted The common technique for psychiatric epidemiological research today is structured interviewing , a technique in which a series of questions is administered by lay interviewers to determine whether an individual is disordered or nondisordered. Concerns of epidemiological research Clinical versus actual prevalence Clinical prevalence is a measure of how many people who seek out mental health services are actually diagnosed with a mental illness, whereas actual prevalence is the number of people in all of society who have a mental illness. It is much easier to study clinical prevalence because people with mental illness are identified by receiving a diagnosis, but epidemiologists are most interested in actual prevalence. To that end, efforts are continually made to improve research techniques in order to better estimate the actual prevalence of mental illness. Sensitivity and specificity Another concern of psychiatric epidemiological studies are the issues of sensitivity and specificity . Sensitivity is a measure of how well a given selection criteria detects all of the people with a specific mental illness. Specificity is a measure of how well the technique identifies people with a mental illness without falsely identifying people ... EJ.
