Various fringe theories have arisen to speculate about purported alternative origins for the human immunodeficiency virus (HIV) and the acquired immunodeficiency syndrome (AIDS), with claims ranging from it being due to accidental exposure to supposedly purposeful acts. Several inquiries and investigations have been carried out as a result, and ...
Duesberg's claim that recreational drug use, rather than HIV, was the cause of AIDS has been specifically examined and found to be false. Cohort studies have found that only HIV-positive drug users develop opportunistic infections; HIV-negative drug users do not develop such infections, indicating that HIV rather than drug use is the cause of AIDS.
Several of the theories of HIV origin accept the established knowledge of the HIV/SIV phylogenetic relationships, and also accept that bushmeat practice was the most likely cause of the initial transfer to humans. All of them propose that the simultaneous epidemic emergences of four HIV groups in the late 19th-early 20th century, and the lack ...
The Oral polio vaccine AIDS hypothesis (OPV AIDS) is a now-discredited hypothesis which argued the AIDS pandemic originated from live polio vaccines prepared in chimpanzee tissue cultures, accidentally contaminated with simian immunodeficiency virus and then administered to up to one million Africans between 1957 and 1960 in experimental mass vaccination campaigns.
Alternative factors may predict health behavior, such as outcome expectancy [24] (i.e., whether the person feels they will be healthier as a result of their behavior) and self-efficacy [25] (i.e., the person's belief in their ability to carry out preventive behavior). The theoretical constructs that constitute the HBM are broadly defined. [4]
The Information-Motivation-Behavioral Skills (IMB) model is a theoretical framework developed by Jeffrey D. Fisher and William A. Fisher in 1992. [1] Initially designed to understand and promote HIV -preventive behaviors, the IMB model has since been applied to various health-related behaviors and interventions.
Kalichman is the director of the Southeast HIV/AIDS Research & Education Project in Atlanta (Georgia, USA) and Cape Town (South Africa); the editor of the journal AIDS and Behavior; and the author of Denying AIDS: Conspiracy Theories, Pseudoscience, and Human Tragedy, an examination of HIV/AIDS denialism.
HIV/AIDS is the leading epidemic that affects the social welfare of Africa. [18] Human Immunodeficiency virus (HIV) can cause AIDS which is an acronym for Acquired Immunodeficiency Syndrome (AIDS), a condition in humans in which the immune system begins to fail, leading to life-threatening infections. Two-thirds of the world's HIV population is ...
