Expand/Contract Questions and Answers

Don't labs report all these disease anyway?
NO! Title 17 requires health care providers to submit a Confidential Morbidity Report (CMR) for all reportable diseases, regardless of whether or not it is also reported by the lab. Labs are only required to report a subset of diseases. Additionally, labs often lack demographic information, risk information, and a clinical interpretation of the lab results all of which are required for an appropriate public health response.
How does the Health Insurance Portability and Accountability Act (HIPAA) affect disease reporting?
HIPAA does not preclude disease reporting and, in fact, makes special allowances for the transfer of Public Health Information (PHI) to the local health authority.
How quickly must disease be reported?
Refer to the back (page 2) of the Confidential Morbidity Report for required deadlines. In general, any disease that may require an immediate public health response (e.g., measles) must be called in ASAP 24/7. Other diseases may be reported by Confidential Morbidity Report (CMR) within one working day or within one week according to page two of the CMR.
Is someone available to answer communicable disease questions?
Yolo County Health Department staff is available for consultation and to answer questions related to communicable disease during business hours by calling 530-666-8645.
Should I wait for lab confirmation before reporting a disease?
For diseases that require an immediate public health response (e.g., measles), DO NOT WAIT TO REPORT – REPORT THESE DISEASES AS SOON AS THEY ARE SUSPECTED. Unusual illnesses or illnesses that may be related to an outbreak or bioterrorism should also be reported as soon as they are identified. For all other diseases where an immediate public health response is not required (e.g., sexually transmitted diseases, hepatitis C), report when diagnosis is confirmed.
What diseases have been reported in Yolo County in the past?

What diseases must be reported?
A current listing of all California reportable diseases and conditions can be found here.
What is the legal basis for disease reporting in California?
Disease reporting requirements have been set forth by the California Legislature in Title 17 of the California Code of Regulations (CCR). Title 17 requires that health care providers report certain diseases to the local health authority using the Confidential Morbidity Report (CMR).

CCR Title 17, Section 2500 describes reportable disease requirements in detail and is available ONLINE. Click on Title 17 Public Health, Chapter 4, Preventive Medical Services, Article 1, Reporting, and see Sections 2500-2511. For HIV non-name reporting, see Section 2641.5, and for Alzheimer's Disease and Related Disorders, see Sections 2800-2812.
Where can I find more information about specific diseases?
California Department of Public Health (CDPH)

Where is testing for blood-lead levels available? How much does testing cost?
Your private physician or health care clinic can test for blood-lead levels. Many private insurance policies cover the cost of testing for blood-lead levels. The cost of a blood-lead test generally ranges from $10 to $75, plus the charge for an office visit. If you have Medi-Cal or if you are in the Child Health and Disability Prevention Program (CHDP), the test is free.
Who must report diseases?
According to Title 17 of the California Code of Regulations, health care providers include physicians, podiatrists, nurse practitioners, physician assistants, registered nurses, nurse midwives, school nurses, infection control practitioners, medical examiners, coroners, veterinarians and dentists. These health care providers are required to report certain diseases to the local health authority. Title 17, Section 2500 describes reportable disease requirements in detail (refer to 'What is the Legal Basis for Reporting in California' FAQ above.)
Who should get a blood-lead test?
- Children age 12 months and 24 months who are enrolled in publicly funded health care such as Medi-Cal, Child Health and Disability Program (CHDP), the Supplemental Nutrition Program for Women, Infants and Children (WIC), or Healthy Families are at high risk and should be tested. Cost for the test is covered by government health programs and most health insurance plans.
- Children enrolled in publicly-funded health care who are between 24 months and 6 years old that have not been tested at the appropriate times.
- Children in Head Start Preschool are required to have a blood lead test for enrollment.
- Young children under six years of age who spend time in homes, childcare centers, or buildings built before 1978 that have chipping or peeling paint should be tested.
  Any infant or child who is thought to be at risk or comes in contact with items that may contain lead should be tested.
- If you don't have a doctor, The Yolo County Children's Health Initiative can assist you. Just call (530) 757-5558 or visit www.yolokids.org. The staff will help you to find the best health insurance for your child.
Why must health care providers report?
Failure to report a reportable disease is a citable offense for health care providers. However, this is not and should not be the primary motivating factor for reporting. Health care providers are the first and only line of defense in recognizing emerging public health issues. The window of opportunity afforded by early reporting directly impacts the effectiveness of any public health response. Reporting of other diseases (e.g., sexually transmitted diseases, hepatitis C) also directly determines federal and state funds that communities may receive for prevention, treatment and case management.
