Riverside Communicable Disease Reporting Guide

Public Health and Welfare California 3 Minutes Read · published February 09, 2026 Flag of California

In Riverside, California, residents and health professionals must follow state and county rules for reporting communicable diseases. This guide explains what to report, who enforces reporting, how to submit required notifications or Confidential Morbidity Reports, and practical steps to stay compliant. The California Department of Public Health maintains the statewide list of reportable conditions and reporting methods [1], while local public health staff provide investigation and follow up.

Report suspected cases promptly to protect your household and community.

What to report and when

Reportable conditions generally include diseases that pose a risk of transmission in the community, outbreaks, and certain exposures. If you are a clinician, laboratory, school, or facility staff, follow state reporting timelines (often immediate or within specified hours) and local instructions.

  • Who: clinicians, labs, hospitals, schools, and certain facilities.
  • When: timelines vary by disease; many require immediate or same-day reporting.
  • How: written Confidential Morbidity Report (CMR), secure electronic systems (CalREDIE), or phone for urgent cases.

Penalties & Enforcement

Enforcement and investigation are carried out by the local health officer and public health staff. In Riverside, county public health and the designated health officer handle case investigations, isolation and quarantine orders, and compliance measures. Specific monetary penalties for failing to report are not specified on the cited page [1]. Where statutes or regulations provide penalties, they are detailed on the controlling state pages.

  • Fines: not specified on the cited page.
  • Escalation: first, repeat, and continuing violations are addressed by ordered remedies or court referral; specific escalation ranges are not specified on the cited page.
  • Non-monetary sanctions: isolation or quarantine orders, written compliance directives, seizure of contaminated materials, and referral to courts for enforcement.
  • Enforcer: the local health officer (Riverside County public health) with authority under state health law.
  • Inspection & complaint pathways: report concerns to local public health or the county communicable disease unit for investigation.
  • Appeals & review: timelines for challenging orders or enforcement actions vary; specific time limits are not specified on the cited page.
If you receive an isolation or quarantine order you should follow instructions and ask the health officer about appeal steps immediately.

Applications & Forms

The primary form used statewide is the Confidential Morbidity Report (CMR) or electronic reporting via CalREDIE; local public health may provide submission instructions or phone numbers. Where no local form is published, submit the CMR or use the state reporting pathway as directed by the county.

Action steps for Riverside residents

  • Report suspected cases: contact Riverside County public health or your healthcare provider immediately.
  • For clinicians and labs: submit CMRs or use CalREDIE as required by state rules.
  • Preserve records: keep lab reports, dates of symptom onset, and exposure history for investigators.
  • If served with an order: follow the order and request written instructions on how to appeal or seek review.
Clinicians and laboratories have specific reporting duties different from general public notification duties.
