HIV-AIDS Pandemic
The global epidemic of HIV/AIDS Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection an individual ... (human immunodeficiency virus infection and acquired immunodeficiency syndrome) began in 1981, and is an ongoing worldwide public health issue. According to the World Health Organization (WHO), as of 2021, HIV/AIDS has killed approximately 40.1 million people, and approximately 38.4 million people are infected with HIV globally. Of these 38.4 million people, 75% are receiving Haart, antiretroviral treatment. There were about 770,000 deaths from HIV/AIDS in 2018, and 680,000 deaths in 2020. The 2015 Global Burden of Disease Study estimated that the global Incidence (epidemiology), incidence of HIV infection peaked in 1997 at 3.3 million per year. Global incidence fell rapidly from 1997 to 2005, to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HIV/AIDS
Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV), a retrovirus. Following initial infection an individual may not notice any symptoms, or may experience a brief period of influenza-like illness. Typically, this is followed by a prolonged incubation period with no symptoms. If the infection progresses, it interferes more with the immune system, increasing the risk of developing common infections such as tuberculosis, as well as other opportunistic infections, and tumors which are rare in people who have normal immune function. These late symptoms of infection are referred to as acquired immunodeficiency syndrome (AIDS). This stage is often also associated with unintended weight loss. HIV is spread primarily by unprotected sex (including anal and vaginal sex), contaminated blood transfusions, hypodermic needles, and from mother to ch ...

The term was created in the 1990s by epidemiology, epidemiologists to study the spread of disease among all men who have sex with men, regardless of sexual identity, to include, for example, Male prostitution, male prostitutes. The term is often used in medical literature and social research to describe such men as a group for research studies. It does not describe any specific sexual activity, and which activities are covered by the term depends on context. As a constructed behavioral category The term ''men who have sex with men'' had been in use in public health discussions, especially in the context of HIV/AIDS, since 1990 or earlier, but the coining of the initialism by Michael Glick, Glick ''et al.'' in 1994 "signaled the crystallization of a new concept." This behavioral concept comes from two distinct academic perspectives. First, it was pursued by epidemiologist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .
