The Ventura County Public Health Communicable Disease (CD) office detects, investigates, controls, and prevents the spread of communicable diseases in Ventura County. The CD office receives Confidential Morbidity Reports (CMR) from laboratories and health care providers for more than 85 legally reportable diseases. Our team investigates these reports, monitors emerging infectious diseases, analyzes disease trends in the county, and works closely with California Department of Public Health (CDPH) and Centers for Disease Control and Prevention (CDC). 

Health care providers are required to report all suspected and confirmed reportable cases of communicable diseases and/or other unusual diseases by filling out a CMR form.
