The Epidemiology Division maintains an active surveillance program of health related conditions within the City of Laredo, Duval, Jim Hogg, Webb, and Zapata Counties. This division investigates communicable diseases and provides disease interventions to detect and contain disease exposure in order to prevent outbreaks. In addition, to safeguard the health and well being of the community, this division conducts statistical analysis to review trends and project health and disease outcomes to be ready to act now and in the future to prevent the spread of disease. Finally, the division mitigates accidental or terrorist nuclear, biological, chemical and incendiary occurrences. The ultimate goal of the Epidemiology Division is to predict health related conditions, identify the risks, and stimulate elements that can lower morbidity and mortality. This division receives more than 900 reports of infectious diseases annually that are then investigated and classified as not a case, probable or as a confirmed case.

Hospitals, clinics, laboratories, and physicians’ offices are required by law to report infectious health related conditions to the Epidemiology Division. For a list of the most current reportable disease conditions in the State of Texas please see https://www.dshs.texas.gov
