In the developing world,
the health sector has only recently begun to use GIS. GIS for Health and the Environment collects and records some of the first attempts to identify and explore opportunities to apply GIS for health in developing countries.
Contents in more details: Proceedings of an International Workshop held in Colombo, Sri Lanka, 5-10 September 1994. The research presented in this book demonstrates how GIS data is being used to show cause-effect relationships between environmental conditions and health. Case studies demonstrate how GIS can be used to monitor tropical diseases, water quality, environmental toxicology, and overall rural health. The book also demonstrates how GIS can provide health researchers, planners, program managers, and policymakers with novel information about the distribution and interaction of disease risk factors, patterns of morbidity and mortality, and the allocation of health resources.

The GIS Primer provides an overview of
issues and requirements for implementing and applying geographic information
It focuses on practical issues concerned with the responsible implementation and application of GIS technology. The primer is directed for those with limited exposure to GIS. It is intended purely as in introductory text with an emphasis on identifying and clearly illustrating fundamental concepts in GIS applications.

Epi Info 2000 is a database and statistics program for public health professionals. Although it can be programmed to produce systems for repeated or permanent use, it can also be used interactively for rapid questionnaire design, data entry, and analysis during an investigation.
Epi Map, the mapping component of Epi Info, is built around MapObjects software from ESRI, the makers of ArcView and ARC/INFO, popular Geographic Information System (GIS) tools. Epi Map displays Shapefiles from these two systems, and thus can use the enormous reservoir of map boundaries and geographic data available on the Internet in ESRI-compatible formats.
Epi Map is designed to show data from Epi Info 2000 files by relating data fields to SHAPE files containing the geographic boundaries. Shapefiles also can contain data on population or other variables, and can therefore provide numeric data that become part of the display either as numerator or denominator. Numeric data can be displayed either as
colour/pattern (choropleth) maps or as dot density maps with the dots randomly distributed within geographic
Point locations can be plotted automatically from data files containing x and y coordinates in various symbols,
colours, and sizes. Shapefiles can contain lines or points to represent streets or point locations, and points can be placed on top of the Shapefile layer to represent homes in which cases occurred or other geographic points of interest.
Most of the work in Epi Map is done from the Map Manager, which allows Layers to be constructed with Shapefiles and related data variables. Layers can be removed or moved to the front or rear of a series of layers. Many properties affecting
colours, shapes, grouping of data, type of display, and other characteristics can be set in the Map Manager.

GeoHealth, Inc. produces
some very useful health extensions to ESRI's ArcView GIS. BodyViewer is a unique GIS product. It allows users to map any database that contains a geographic reference (e.g., postal codes, street addresses, census tract numbers) and an ICD-9 or ICD-10 code. BodyViewer displays the prevalence of disease types by "mapping" it to a picture of the human body and then displays the disease on a map.
BodyViewer CR (Cancer Registry) is designed to diagram, map and report ICD-O codes.
Data is first "mapped" to a diagram of the human body so users can understand where and how prevalent cancer is from an anatomical view. Then
users can visualise where the cancer is located geographically by clicking on any part of the anatomy. Also
they can map individual codes or site groupings such as "Lip, Oral Cavity and Pharynx". For even more detail
users can choose to map O-codes by their cell morphology. This is an indispensable tool to understand and communicate cancer data.
PatientAccess is another tool that measures geographic accessibility. It measures the distance between any two sets of locations. For instance,
users could analyse the distance between patients and their doctors or managed care
subscribers and their network providers or the distance between a population and a suspected environmental hazard. PatientAccess automatically generates a series of maps and reports to demonstrate accessibility.
PatientAccess DriveTime performs all of the functions of PatientAccess and takes into account the actual road network patients must travel.
is a medical decision support software package created and updated by C.Y
Informatics, and used in over 45 countries around the world, including the US
Navy. It combines the power of medical geography and epidemiology, with
clinical management (i.e., diagnosis and treatment) of infectious diseases.
Users start by selecting the symptoms and signs they want to diagnose. GIDEON
then generates a set of suitable differential diagnoses and uses its Bayesian matrix
to compute the probability of each diagnosis in this set, taking into
consideration the country of disease acquisition. GIDEON also features a
comprehensive database of microbiological tests, drug interactions,
vaccinations and much more.. (Status: A very useful program but you need to order your copy from www.gideononline.com/order.htm - Source: CY

With an emphasis on statistical database development for sub-national applications and

geographical information system for thematic and interpretative analysis and presentation -
as well as information and decision support system for population activities.
Combining graphics, spreadsheet interface and mapping capabilities with an integrated
geographical database, PopMap provides maps and graphics database support for planning and
administration of population activities with important geographical or logistical context,
or for facilitating geographical or graphical expression of population indicators and

ClusterSeer offers data visualization tools and state-of-the-art statistical methods to explore spatial and temporal patterns of events. ClusterSeer methods can be used to investigate disease clusters in space, in time, and spatial clusters that depend on time (spatio-temporal interaction). (Project Leaders: Geoff Jacquez and Leah Estberg)
The SaTScan software analyses spatial, temporal and space-time point
data using the spatial, temporal, or space-time scan statistic. It is designed for any of the following interrelated purposes:
To evaluate reported spatial or space-time disease clusters, to see if they are statistically significant.
To test whether a disease is randomly distributed over space or over time or over space and time.
To perform geographical surveillance of disease, to detect areas of significantly high or low rates.
SaTScan uses either a Poisson based model, were the number of events
in an area is Poisson distributed under the null hypothesis, or a Bernoulli model, with 0/1 event data such as cases and controls. The
program adjusts for the underlying in homogeneity of a background population. With the Poisson model it can also adjust for any number
of categorical covariates provided by the user.
