California Health Alert Network (CAHAN)


What is the California Health Alert Network?

The California Health Alert Network (CAHAN) is a state-sponsored web-based system used in San Joaquin County to send warnings of impending or current situations that may affect the public's health. In addition CAHAN provides a collaborative work environment where emergency preparedness planning and response information can be shared between local and state health agencies and emergency response partners.

What is the alerting capability of CAHAN?

When an alert message is sent, CAHAN sends the message to e-mail addresses, telephones, faxes, e-mail capable alphanumeric pagers, and cell phones. The California Department of Health can send alerts to all county health departments; county health departments can send alerts within their county, to neighboring county health departments, and to the California Department of Health Services.

What is the secure collaborative work environment?

CAHAN contains an on-line repository for documents and files that provides tools for collaboration, development, and sharing of information related to emergency events, planning, epidemiology, laboratory capacity, risk communication, training, and preparedness.

Who are the intended users of CAHAN?

The system is intended for a wide spectrum of state and local health response officials, preparedness coordinators, and partner agencies in the county's emergency and public health services and preparedness sectors. User information is maintained through a secure web portal requiring a user-id and password that is not accessible to the general public.
