The Science Issue and Relevance

The U.S. Geological Survey (USGS) hosts a website for the Centers for Disease Control and Prevention (CDC) to make epidemiological information in the United States available to health officials, epidemiologists, researchers, and the public to include news outlets. The website also plays a critical role in facilitating the CDC's need to work closely with state health departments and their vector-borne disease coordinators to monitor the spread of reportable arboviral diseases.

Methodology for Addressing the Issue
The USGS is collaborating with the CDC in monitoring eight arboviral diseases: West Nile virus (WNV), St. Louis Encephalitis (SLE), Eastern Equine Encephalitis (EEE), Western Equine Encephalitis (WEE), La Crosse Encephalitis (LAC), Powassan (POW), Dengue (DEN), and Chikungunya (CHIK). The USGS receives weekly arboviral case count data from CDC and provides interactive online mapping and graphic products for all 50 states, Puerto Rico, and the U.S. Virgin Islands that show the occurrence and distribution of these diseases by state, by county, and by week of occurrence for the appropriate categories of disease cases during the active reporting season. These products are displayed on the USGS web site: https://diseasemaps.usgs.gov/. The CDC Near-Real-Time Mapping project is a long running partnership between the USGS and CDC. It began in 2000 with the mapping of the West Nile Virus activity as part of the President's Security and Prosperity Partnership initiative and expanded in 2006 to include all reported arboviral diseases, by building upon the success of mapping West Nile Virus activity from 2000-05.

Future Steps
The USGS works with CDC annually to make improvements to the web site and add emerging arboviral diseases of concern.
