Disease Reporting

The Oklahoma State Board of Health officially establishes certain diseases as reportable by health practitioners, laboratory personnel and county health departments.  The list of reportable diseases and pathogens in Oklahoma may be obtained by referring to the What to Report section on this web page.  All disease reports are investigated to determine the danger to a specific population group or to the general population at large.  These diseases can be prevented or controlled by administering interventions such as immunization, immune globulin, vector control, or by other control methods. Information is collected on all disease reports to observe increasing and/or decreasing trends in disease occurrence, and to gather information regarding the causes of disease in Oklahoma.  This enables the Oklahoma State Department of Health to evaluate and target our control, education and prevention efforts across Oklahoma. 

Title 63 Oklahoma Statute (O.S.) 1981 §1-503 mandates the reporting of cases of diseases and conditions by Oklahoma healthcare providers and laboratories to the OSDH.

The secure, web-based Public Health Investigation and Disease Detection of Oklahoma (PHIDDO) is the preferred method of reporting diseases and conditions to the OSDH, aside from the 2019 Novel Coronavirus (COVID-19). COVID-19 lab reporting occurs through the SpringML web portal and COVID-19 case reporting occurs via the OSDH Case Investigation (OSDHCI) application.
