Estimates of New HIV Infections in the United States, 2006 - 2009

This information sheet presents new estimates of the annual number of new HIV infections (HIV incidence) in the United States released by CDC in August 2011. The estimates, for 2006 through 2009, are the first multi-year estimates using CDC’s national HIV incidence surveillance methodology, which is based on direct measurement of new HIV infections using a laboratory test (the BED HIV-1 Capture Enzyme Immunoassay) that can classify new diagnoses as either recent or long-standing HIV infections.

Interferon-Gamma Release Assays (IGRAs) - Blood Tests for TB Infection

It notes that two IGRAs have been approved by the US Food and Drug Administration (FDA) and are commercially available in the United States. The information sheet explains how the IGRAs work; the advantages, disadvantages, and limitations of IGRAs; steps in administering these tests; interpretation; recommendations on when to use them; and whether IGRAs can be given to persons receiving vaccinations.
