Reporting Diseases

Disease Reporting Requirements 

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) requires all heath care providers knowing of or in attendance on a case or suspected case of any of the mandated reportable diseases or conditions to report the case to the local health department where the patient resides. ‘Health care provider’ is defined as a physician, surgeon, veterinarian, podiatrist, nurse practitioner, physician assistant, registered nurse, nurse midwife, school nurse, infection control practitioner, medical examiner, or dentist.

Additionally, Section 2505 requires laboratories to report laboratory-testing results and Section 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.

All reports remain confidential.
