Report a Disease


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


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. More than 85 diseases and conditions are reportable in Contra Costa County.

Veterinarians are required to report six animal diseases: Anthrax, Brucellosis (except Brucella canis), Plague, Rabies, Tularemia and Viral Hemorrhagic Fevers.


´╗┐Physicians who need to report a suspected public health emergency should contact the Public Health division immediately at 925-313-6740; or after hours, call the sheriff's dispatch at 925-646-2441 and ask for the Health Officer On Call.
Health care providers and others may also fax us "Confidential Morbidity Reports" (see below for fax numbers). The different types of CMR forms are available here:
