CDC’S National HIV Surveillance System is the primary source for monitoring HIV trends in the United States. CDC funds and assists state and local health departments to collect the information. Health departments report de-identified data to CDC so that information from around the country can be analyzed to determine who is being affected and why.

Surveillance is the ongoing, systematic collection, analysis, interpretation, and dissemination of data regarding a health-related event. HIV surveillance collects, analyzes, and disseminates information about new and existing cases of HIV infection (including AIDS). The ultimate surveillance goal is a nationwide system that combines information on HIV infection, disease progression, and behaviors and characteristics of people at high risk. By meeting this goal, CDC can direct HIV prevention funding to where it is needed the most. AtlasPlus was created to provide an interactive platform for accessing data collected by CDC’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (NCHHSTP). This interactive tool provides CDC an effective way to disseminate data, while allowing users to observe trends and patterns by creating detailed reports, maps, and other graphics. Recent updates to this resource allow users to explore the latest HIV data at the national-, state-, or county-level. Disease rates can be analyzed by demographic variables, transmission categories, year and trends over time. In this new version, users can also create 2 side-by-side maps or charts. New charting capabilities include: line graphs by year; pie charts for sex; bar charts by state and country; bar charts for age, race/ethnicity, and transmission category.
