Disease Reporting

Public Health relies on medical providers, school officials and the public to notify us when they encounter cases or suspected cases of certain diseases or conditions.

Public Health Nurses (PHNs) investigate reported diseases and, as appropriate, involve epidemiologists, environmental health specialists, the public health laboratory, or the health officer in their investigations.

The state of California requires doctors, surgeons, nurses, practitioners, coroners, dentists, veterinarians, administrators of health facilities and clinics to report cases or suspected cases of certain diseases and conditions to the local health department. Anyone in charge of public or private schools or preschools also must report cases or suspected cases of these diseases.
