Modern information technologies in environmental health surveillance. An overview and analysis.
In recent years we have witnessed the massive introduction of new information technologies that are drastically changing the face of our society. These technologies are being implemented en masse in developed countries, but also in some pockets of developing nations as well. They rely on the convergence of several technologies such as powerful and affordable computers, real-time electronic measurement and monitoring devices, massive production of digital information in different formats, and faster, wireless communication media. Such technologies are having significant impacts on every domain of application, including environmental health surveillance. The current paper provides an overview of those technologies that are having or will likely have the most significant impacts on environmental health. They include World Wide Web-based systems and applications, Database Management Systems and Universal Servers, and GIS and related technologies. The usefulness of these technologies as well as the desire to use them further in the future in the context of environmental health are discussed. Expanding the development and use of these technologies to obtain support for global environmental health will require major efforts in the areas of data access, training and support.
