Report a Public Health Emergency

If you are a first responder or medical/health organization representative and need to talk to a public health representative regarding an emergency situation, such as multi-casualty incidents (MCIs), MHAOC requests, threats to the medical and public health system or medical and mutual aid requests, call 1-805-380-3411.

This is a 24/7 phone number for the EMS Duty Officer which functions as the MHOAC Program until the County Health Agency Department Operations Center (CHADOC) is activated.

For all other public health emergency calls, such as communicable disease, first responders may call:

  • 1-805-788-2067 during regular business hours
  • 1-805-781-4553 during weekends, after hours and holidays
