Medical Health Operational Area Coordinator (MHOAC) Program

General information


The Medical Health Operational Area Coordinator (MHOAC) Program is authorized by the California Health and Safety Code Section 1797.153.  The MHOAC position represents the single point of contact for the MHOAC program and is responsible for monitoring and ensuring adequate medical and health resources are in place during a local emergency.  The MHOAC is authorized to make and respond to requests for mutual aid from outside of San Mateo County.

During non-emergency operations and the initial phases of an emergency, the MHOAC Program operates in a duty officer mode and is on-call 24/7. Once the San Mateo County Health Department Operations Center (Health DOC) is activated, the MHOAC Program functions can be distributed to various positions within the Health DOC. The MHOAC may also be at the County EOC as the Medical Health Branch Director.

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 the MHOAC directly by logging into ReddiNet and calling the individual listed under System Contacts. If you are not able to get through to the contact through this manner, please contact dispatch at 650-363-4963 and request to be put in touch with the EMS Duty Officer/MHOAC On-Call.
