The OC Health Care Agency works every day to help keep our community healthy and safe. We monitor diseases, provide vaccines, check that our food is safe to eat, and track water quality to protect public health. We also share helpful information so people can stay informed and take care of themselves. Our programs support families, children, and older adults.
