Communicable Disease Investigation
Yolo County staff investigate individual reports of highly contagious, or communicable disease and take whatever steps are necessary to control outbreaks in the community. These staff ensure that the affected person and their close personal contacts are treated as necessary, develop programs to prevent future disease outbreaks, provide public and professional education and collaborate with other organizations at the State and Local level to control the spread of disease.
Once a reportable disease is reported, an investigation is started to:
- Confirm the diagnosis and the original source of the disease
- Verify the disease
- Locate affected persons
- Provide affected persons with information about the disease
- Look for any common mode of transmission between affected persons
- Provide affected persons and the public, if necessary, with information about the disease, including: symptoms, how diagnosis is confirmed, how the disease is spread, and how to prevent it.
Sometimes Communicable Disease staff work with other agency staff to control or stop an outbreak. For example, cases involving a restaurant or day care facility will require coordination response between the Communicable Disease staff and Environmental Health.
The Communicable Disease Unit will continually update this list when issuing advisories, alerts and press releases about county, state, and national outbreaks that have potential to impact visitors and residents of Yolo County.
