Surveillance & Assessment

As one of the primary functions of a local health department, Reportable Disease Surveillance serves as the early alert system for all communicable diseases. Three Rivers District Health Department is notified of all lab-confirmed communicable diseases and conducts public health investigations through utilization of the National Electronic Disease Surveillance System (NEDSS). Our partnership with local hospitals, health care providers, nursing homes, and schools to receive prompt notification of reportable diseases enables us to begin the disease investigation process in a timely manner as well as to disseminate helpful information to prevent their further spread. Syndromic surveillance is a way for Three Rivers to collect real time information on symptoms that may indicate local disease outbreaks. Syndromic surveillance is conducted in Dodge, Saunders, and Washington Counties as follows:

  • 55 schools report absences every week throughout the school year
  • 21 nursing homes report influenza-like-illnesses every week throughout the influenza season
  • 3 hospitals report influenza-like-illnesses every week throughout the influenza season
  • A local physician serves as one of 17 statewide sentinel physicians and reports influenza-like-illnesses seen in his office every week throughout the influenza season

Three Rivers uses Geographic Information System (GIS) Mapping to view, understand, question, interpret, and visualize data in many ways that help to reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts. GIS helps us answer questions and solve problems by allowing us to look at our data in a way that is quickly understood and easily shared.
