Public health is information transfer. Public health
scientists read literature and talk with colleagues to generate ideas.
They write grants to obtain resources to conduct research. Public
health research involves data collection, analysis, and manuscript preparation
all of which are information transfer. Results are published to transmit
information and read by public health workers to improve health.
We are now in an information revolution where rapid, almost free, transmission
of information is possible. If public health can harness this revolution,
there could be rapid improvement in public health.
