Communicable Disease Reporting

General information

The Communicable Disease Control Program staff works around the clock to receive and respond to communicable disease reports.

Medical providers and public health professionals are legally required by Title 17 (Section 2500) of the California Code of Regulations to report suspected, lab-confirmed and clinical diagnoses of specific diseases and conditions within specified time frames. Additionally, anyone in charge of any type of school is also required to report these diseases (Section 2508), as are Laboratories (Section 2505).

Why report?

The primary objectives of disease surveillance are:

  • To protect the health of the public
  • To determine the extent of morbidity within the community
  • To evaluate the risk of transmission
  • To intervene rapidly when appropriate, to control and prevent the spread of disease

Meaningful Use

San Mateo County Health coordinates with providers who are in the process of trying to meet Stage 1 Meaningful Use requirements for Public Health reporting objectives. The Public Health aspects of the requirements are for transmission of immunization data, syndromic surveillance data, and electronic laboratory data.

Syndromic surveillance:  This is under development. For more information contact Scott Morrow, Health Officer, at or (650) 573-2519.

Immunization data:  The web based California Immunization Registry (CAIR) receives data directly from providers and provides confirmation of successful test messages for meaningful use. This State site contains the contact information for the Bay Area regional technical support person for CAIR who can coordinate with you for use of the CAIR system.   If you need further information from San Mateo County, contact Scott Morrow, Health Officer, at or (650) 573-2519 or Robyn Ziegler, San Mateo County Health Immunization Coordinator, or at (650) 573-2878.

Electronic laboratory and other reportable disease data: California Reportable Disease Information Exchange (CalRedie) receives data directly from providers and provides electronic acknowledgement of receipt for meaningful use. Insert link to their site.  Contact Scott Morrow, Health Officer, at or (650) 573-2519. To be set up to use the CalRedie system, contact the Communicable Disease Control Program at or 650-573-2346.

Electronic Reporting of Notifiable Diseases through CalREDIE

California Reportable Disease Information Exchange (CalREDIE) is the California Department of Public Health’s (CDPH) communicable disease reporting and surveillance system of record. The system is web-based and PHIN-compliant and it is used by state and local public health officials and healthcare providers. As of today, 95% of California local health jurisdictions are using CalREDIE in some capacity.

The CalREDIE Provider Portal allows healthcare providers to electronically submit Confidential Morbidity Reports (CMRs) directly to their local health department via the HTTPS secure interface. The Provider Portal can be used for all Title 17 communicable diseases that are required by law to be reported to the local health department. Case information is accessed by the local jurisdiction immediately for review and investigation. This timely reporting option provides real-time assessment of potential outbreaks and unusual disease patterns. Highlights of the Provider Portal include: easy point and click navigation; printable receipt to use as a record of the report; ability for the provider to view previously submitted reports; ability for the provider to generate reports of all submissions; and the ability for the provider to upload and store additional paperwork or files when submitting a report.

Interested providers can submit a Provider Portal account request via the CalREDIE Account Request Portal.

Failure to report or delay in reporting

Delay or failure to report communicable diseases has contributed to secondary transmission in the past. Under the California Code of Regulations, Title 16 (Section 1364.10), failure to report a communicable disease is a misdemeanor punishable by a fine of not less than $50 nor more than $1,000, or by imprisonment for a term of not more than 90 days, or both. Each day the violation is continued is a separate offense. The Medical Board of California has made failure to report in a timely manner a citable offense under the California Business and Professions Code (Section 2234), “Unprofessional Conduct.”
