DISEASE INVESTIGATION
Our epidemiologists work closely with healthcare providers to collect and analyze data, helping keep communities healthy and reduce the spread of communicable diseases. When a patient tests positive for a reportable disease, the healthcare provider notifies the local public health department, and we follow up with patients as needed to provide education, resources, and support to slow the spread. To learn about diseases commonly found in Southwest Utah, please refer to our pages on COVID-19, Influenza (Flu), Measles, Rabies, Tuberculosis, Valley Fever, and West Nile Virus. For a comprehensive directory, you can review the Utah Department of Health and Human Services A-Z Index of Disease Information. If you are a provider needing to report a communicable disease, visit the Utah DHHS Disease Reporting page.
