Vision and Mission
Our Vision: Los Angeles County residents are protected from the public health consequences of both natural and intentional emergencies.

Our Mission: To prevent and mitigate the public health consequences of natural or intentional emergencies for Los Angeles County residents through threat assessment, planning, improved operational readiness, and timely response.

Welcome to the Los Angeles County CAHAN Expansion Workshops website! The California Health Alert Network (CAHAN) is the State of California’s official public health alerting system available on a 24/7/365 basis for distribution of health alerts, dissemination of prevention guidelines, coordination of disease investigation efforts, preparedness planning, and other initiatives that strengthen state and local preparedness and response efforts.

CAHAN is used by both the California Department of Public Health (CDPH) and Los Angeles County Department of Public Health (LACDPH). CAHAN users may receive alerts from both the state and local jurisdictions. In Los Angeles County, the CAHAN system is a key component of preparedness and response to significant public health incidents or potential threats to the public’s health. CAHAN works to protect the health and safety of Los Angeles County residents, and is used for the distribution of health alerts and notifications that reflect local guidance and resources.

There are a variety of resources available on this website to train and assist LA County CAHAN participants, which are easily accessible by clicking the links on the left. On this website you can:

  • Access General Info about CAHAN
  • Find out how to enroll in CAHAN
  • Register to take the Los Angeles County Online CAHAN Training Course
  • Access CAHAN resources, such as user guides and reference materials

Thank you in advance for your participation in this important effort that will assist with public health preparedness for the people of California by ensuring immediate alerting and notification is available between public health partners.
