California Health Alert Network



The California Health Alert Network (CAHAN) is the State of California's web-based information and communications system available on a 24/7/365 basis for distribution of health alerts, dissemination of public guidelines, coordination of disease investigation efforts, preparedness planning and other initiatives that strengthen state and local preparedness. CAHAN participants have the ability to receive alerts and notifications via alphanumeric pager, e-mal, fax and phone (cellular & landline).

CAHAN links critical health and emergency response partners together to provide:

  • Rapid and secure communications system among state and local agencies, health care providers, emergency management officials and other emergency response partners.
  • Dissemination of announcements from local, state or federal public health authorities to inform health and medical service personnel of likely or imminent dangers to the health of their community.
  • Secure collaborative environment to develop and share information for emergency preparedness planning and response.
