Report a Disease

Why Report?

We rely on medical providers, school officials and other community partners to notify us when they encounter cases or suspected cases of certain diseases or conditions. Reporting allows local health departments to keep track of the diseases in the community and to take action to prevent diseases from spreading.

Who is required to report?

What is permitted in the law as disclosures to Public Health?

The Privacy Rule of the Health Insurance Portability and Accountability Act (HIPAA) of 1996 sets standards for the use and disclosure of private health information. The Privacy Rule does allow communicable disease reporting as part of permitted disclosures for public health activities (CFR Title 14 §164.512). No consent or authorization is required.

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.
Examples of public health emergencies include a suspected or confirmed case of measles, suspected or confirmed meningococcal disease, suspected botulism, suspected illness due to a bioterrorism agent, a severe outbreak or any unusual illness that requires immediate containment.
