It is evidently clear from the discussion that the part of the world that is affected worst by HIV infection is sub-Saharan Africa. As of now, there is neither a cure nor a vaccine for AIDS. Thus, combating the disease is a major challenge for health care providers and biomedical scientists. AIDS and HIV infection represents one of the most public -pressing public health policy and public health problem in the world. Currently, AIDS is pandemic and has the significant impact on the health care costs. In the current era, HIV infection is considered to be in the end stage of a chronic disease with rapid spread among Hispanics and Blacks. Though the disease was first identified in 1981, the mode of transmission of the disease and a causating agent was discovered only in 1984. In 1985, detection of the virus was developed and applied to blood transfusions. In 1987, anti-retroviral agents were manufactured and since then there has been a constant upgrading of drugs to combat infection, but with no cure or vaccine for the disease. Currently, it is estimated that 850,000 to 950,000 Americans are living with HIV infection/AIDS. The disease is a national epidemic with severe effect on specific groups like injection drug users, gay and bisexual men, young individuals and racial and ethnic minorities. Currently, it is also increasingly affecting communities which are economically backward and also women. Since the time AIDS was diagnosed for the first time in the United States, the relationships among politics, science and health care policy have changed drastically. In the 1980s, the HIV epidemics politics were dominated mainly by four interacting factors fear and fascination, individuals involved in the contraction and spread of the disease, endemic problems of the social policy of the United States and the impact of scientific knowledge advances on policy.
