About COCA

Image of COCA logo

The CDC Emergency Communication System’s Clinician Communication Team manages the Clinician Outreach Communication Activity (COCA) to ensure that clinicians have the up-to-date information they need.  COCA is designed to provide two-way communication between clinicians and the CDC about emerging health threats, such as pandemics, natural disasters, and terrorism.


  COCA operates in order to:

  • Help clinicians provide the best possible care to patients by supplying them with the most current and reliable information.
  • Disseminate evidence-based health information and public health emergency messages to clinicians.
  • Provide and promote emergency preparedness and response training opportunities.
  • Obtain feedback from healthcare provider audiences to help improve emergency communications to clinicians.
  • Identify clinical issues during emergencies to help direct communication strategy and outreach to clinicians.

COCA serves a wide variety of clinicians, including: physicians, nurses, physician’s assistants, pharmacists, paramedics, veterinarians, epidemiologists, public health practitioners, and state and local health department officials.  In addition, COCA partners with 176 professional organizations allowing for extended outreach to large populations of clinicians.

Clinicians have varying information needs, so COCA provides a variety of products and services to serve these diverse needs, including: email updates about new/updated CDC information on emerging health threats; training and conference announcements; direct email access for questions and feedback via coca@cdc.gov ; and Continuing Education opportunities, including COCA Conference Call presentations.

COCA invites all clinicians to Sign-Up for COCA Email Updates and Reminders via coca@cdc.gov.
