Who We Are

The Public Health Informatics Office (PHIO) in CDC’s Center for Surveillance, Epidemiology, and Laboratory Services (CSELS) is reimagining a better data and information superhighway to protect Americans from health threats.

To achieve this, PHIO is partnering with

  • Private sector professionals to provide cutting edge innovative solutions that streamline data,
  • Technical experts to solve real data exchange challenges with electronic health records, and
  • Local, state, and federal public health agencies to address their informatics needs.
