Act Against AIDS™ is a multi-faceted national communication campaign launched by CDC and the White House to combat complacency about the HIV/AIDS crisis in the United States, refocus national attention on the domestic epidemic, and reduce HIV incidence. Act Against AIDS™ focuses on raising HIV awareness among all Americans, and reducing the risk of infection among the hardest-hit populations – gay and bisexual men of all races; African Americans; Latinos; and other communities disproportionately affected. The multiple campaign phases use mass media (TV, radio, newspapers, magazines, and the Internet) and direct-to-consumer communication channels to deliver important HIV prevention messages. Since its launch in April 2009, the Act Against AIDS™ campaign has reached more than one billion media impressions through TV, radio, donated media space, Web videos and advertising across the country. The Act Against AIDS™ campaign also supports the Act Against AIDS Leadership Initiative (AAALI), a network of national African American, Latino, and LGBT (lesbian, gay, bisexual and transgender) organizations working to educate and mobilize their communities on HIV prevention. The Act Against AIDS™ campaign is one critical component of CDC's comprehensive HIV prevention efforts.
