The public health workforce.

Defining the public health workforce and specifying its performance requirements present equal challenges as the nation anticipates public health needs for the twenty-first century. The core group of professionals employed by government public health agencies works in close partnership with a wide range of public, private, and voluntary organizations. The wider circle includes almost all physicians, dentists, and nurses, plus many other health, environmental, and public safety professionals. The task of ensuring that this workforce is prepared with skills and knowledge to face both identified and emerging public health challenges is immense.
