Surveillance Resources

The following resources can assist epidemiologists and data analysts in the collection and reporting of vector-borne disease surveillance data.

National Surveillance Systems

ArboNET

ArboNET is a national arboviral surveillance system managed by CDC and state health departments. In addition to human disease, ArboNET maintains data on arboviral infections among presumptive viremic blood donors, veterinary disease cases, mosquitoes, dead birds, and sentinel animals. ArboNET diseases maps are available here.

In 2019, a tick module was developed within ArboNET to capture data on tick distributions and abundance as well as pathogen presence and prevalence in ticks by county.

National Notifiable Diseases Surveillance System (NNDSS)

To protect Americans from serious disease, the National Notifiable Diseases Surveillance System (NNDSS) helps public health monitor, control, and prevent about 120 diseases. Through NNDSS, CDC receives and uses these data to keep people healthy and defend America from health threats.

Notifiable disease surveillance begins at the level of local, state, and territorial public health departments (also known as jurisdictions). Jurisdictional laws and regulations mandate reporting of cases of specified infectious and noninfectious conditions to health departments. The health departments work with healthcare providers, laboratories, hospitals, and other partners to obtain the information needed to monitor, control, and prevent the occurrence and spread of these health conditions.

Final annual case counts of nationally notifiable diseases:

• Data through 2015 can be found in the MMWR Summary of Notifiable Diseases.
• Data from 2016 forward are found in CDC WONDER.
