When disaster strikes, local medical and health resources may be inadequate to meet the demand. The Medical/Health Mutual Aid System is designed to address this issue by facilitating the distribution of regional, state, and/or federal resources to the
area(s) in need.
In California the Medical/Health Mutual Aid System is facilitated by grouping counties, referred to as Operational Areas, together to form six Mutual Aid Regions. Within a region, if disaster strikes, resources are distributed
from the unaffected Operational Areas to the affected one.
San Joaquin County is part of Region IV. Other counties in Region IV include Alpine, Amador, Calaveras, El Dorado, Nevada, Placer, Sacramento, Stanislaus, Tuolumne, and Yolo.
