Reporting Diseases

Disease Reporting Requirements for Health Care Providers and Laboratories

Disease reporting is the foundation of public health surveillance. The reporting of specific diseases is critical to public health and required by law.

Title 17, California Code of Regulation, Section 2500 (Division 1, Chapter 4, Article 1)

•           §2500 (b) It shall be the duty of every health care provider, knowing of or in attendance on a case or suspected case of any of the diseases or conditions listed, to report to the local health officer for the jurisdiction where the patient resides. Where no health care provider is in attendance, any individual having knowledge of a person who is suspected to be suffering from one of the diseases or conditions listed may make such a report to the local health officer for the jurisdiction where the patient resides.

•           §2500 (c) The administrator of each health facility, clinic or other setting where more than one health care provider may know of a case, a suspected case or an outbreak of disease within the facility shall establish and be responsible for administrative procedures to assure that reports are made to the local health officer.

•           §2500 (a)(14) ‘Health care provider’ means a physician and surgeon, a veterinarian, a podiatrist, a nurse practitioner, a physician assistant, a registered nurse, a nurse midwife, a school nurse, an infection control practitioner, a medical examiner, a coroner, or a dentist.

•           §2505 requires laboratories to report laboratory testing results, including molecular and pathologic results, suggestive of diseases of public health importance to the local health department. Laboratories must report any initial findings as well as any subsequent findings. In addition, laboratories must report negative test results or findings when requested by the Department or a local health officer

•           §2508 requires anyone in charge of a public or private school, kindergarten, boarding school, or day nursery to report the presence or suspected presence of any of the reportable diseases to the local health department.

Failure to report is a misdemeanor (Health & Safety Code §120295) and is a citable offense under the Medical Board of California Citation and Fine Program (Title 16, CCR, §1364.10 and 1364.11).

All reports remain confidential.
