There have been dramatic improvements in health during the past 50 yea
rs, and public health measures have made a major contribution. Much of
public health consists of information transfer. The application of te
lecommunications technology to public health and preventive medicine w
ould enhance our ability to transmit information and improve global he
alth. The idea of telemedicine has received considerable attention but
has not thus far included preventive medicine. We have outlined a glo
bal electronic health network with seven main components: connectivity
, telemonitoring of disease, ''distance education for public health wo
rkers, electronic connection of nongovernment organizations, a combine
d degree in public health and communications, an electronic scientific
research sewer, and a home page on the World Wide Web. A commitment t
o the integration of telecommunications and public health holds great
promise for improving the health status of the world's population.
