It advocates on behalf of Black and Latino people with AIDS and their families and works for prevention of HIV and AIDS. In 1998, Levy helped pass HIV Reporting and Partner Notification. It was the most controversial HIV legislation in New York State history . The legislation changed the way New York State tracked new HIV and AIDS cases i.e. Partner Notification. Prior to the legislation, the federal government's Ryan White Program allocated money based on the proportion of patients with AIDS in each region. The highest number of AIDS cases was in New York City among white gay men. Consequently, the white gay population received the most money. The new legislation changed this allocation to give more funding to people who were newly diagnosed with HIV infection. A majority of people with HIV diagnoses were black and Latino heterosexuals. Assemblywoman Nettie Mayersohn sponsored a Bill that required people infected with HIV to notify their sexual partners. The 'Black and Latino AIDS Coalition' was the only AIDS organization in New York State to support Assemblywoman Mayersohn's bill. Levy engaged in heated debates raging in the HIV community concerning the need for establishing a system of tracking HIV infection.

Context_7 : In South Africa, HIV/AIDS denialism had a significant impact on public health policy from 1999 to 2008, during the presidency of Thabo Mbeki. Mbeki criticized the scientific consensus that HIV does cause AIDS beginning shortly after his election to the presidency. In 2000, he organized a Presidential Advisory Panel regarding HIV/AIDS including several scientists who denied that HIV caused AIDS. In the following eight years of his presidency, Mbeki continued to express sympathy for HIV/AIDS denialism, and instituted policies denying antiretroviral drugs to AIDS patients. Instead of providing these drugs, which he described as "poisons", shortly after he was elected to the presidency, he appointed Manto Tshabalala-Msimang as the country's health minister, who promoted the use of unproven herbal remedies such as ubhejane, garlic, beetroot, and lemon juice to treat AIDS, which led to her acquiring the nickname "Dr. Beetroot." These policies have been blamed for the preventable deaths of between 343,000 and 365,000 people from AIDS. As of 2008, Mbeki has remained silent about his views and policies on AIDS; according to "The New York Times", his spokesman, Mukoni Ratshitanga, said Mr. Mbeki would not discuss his thinking on HIV and AIDS, explaining that policy decisions were made collectively by the cabinet and so questions should be addressed to the government. Upon becoming president in 2008, Mbeki's successor, Kgalema Motlanthe, appointed Barbara Hogan as health minister to replace Tshabalala-Msimang on the first day of his presidency. Hogan told "The New York Times", “The era of denialism is over completely in South Africa.” Context_8 : The eighth edition of Dancing Stars was broadcast from March 1 to May 17, 2013 on ORF1 and was presented by Mirjam Weichselbraun and Klaus Eberhartinger.
