HIV Prevalence
The human immunodeficiency virus (HIV), which causes AIDS, varies in prevalence from nation to nation. Listed here are the prevalence rates among adults in various countries, based on data from various sources, largely the CIA World Factbook. As of 2022, around 39 million people, or 0.7% of the population, were estimated to be infected with HIV globally. Prevalence was higher among sex workers, gay and bisexual men, people who inject drugs, transgender people, and prisoners. The HIV pandemic is most severe in Southern Africa. Over 10% of all people infected with HIV/AIDS reside within the region. Adult HIV prevalence exceeds 15% in Eswatini, Botswana, Lesotho and Zimbabwe, while an additional six countries report adult HIV prevalence of at least 10%. In absolute numbers, South Africa (9.2 million), followed Tanzania (2.55million) and Mozambique (2.48 million) and Nigeria (2.45million) had the highest HIV/AIDS number of cases by the start of 2024. While South Africa's large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Human Immunodeficiency Virus
The human immunodeficiency viruses (HIV) are two species of ''Lentivirus'' (a subgroup of retrovirus) that infect humans. Over time, they cause AIDS, acquired immunodeficiency syndrome (AIDS), a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. In most cases, HIV is a sexually transmitted infection and HIV/AIDS#Transmission, occurs by contact with or transfer of blood, pre-ejaculate, semen, and Vaginal lubrication, vaginal fluids. Non-sexual transmission can occur from an infected mother to her infant during pregnancy, during childbirth by exposure to her blood or vaginal fluid, and through breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected White blood cell, immune cells. Research has shown (for both same-sex ...

UNAIDS
The Joint United Nations Programme on HIV and AIDS (UNAIDS) (, ONUSIDA) is the main advocate for accelerated, comprehensive and coordinated global action on the HIV/AIDS pandemic. The mission of UNAIDS is to lead, strengthen and support an expanded response to HIV and AIDS that includes preventing transmission of HIV, providing care and support to those already living with the virus, reducing the vulnerability of individuals and communities to HIV and alleviating the impact of the epidemic. UNAIDS seeks to prevent the HIV/AIDS epidemic from becoming a severe pandemic. UNAIDS is headquartered in Geneva, Switzerland, where it shares some site facilities with the World Health Organization. It is a member of the United Nations Development Group. Currently, Winnie Byanyima leads UNAIDS as executive director. Former executive directors are Peter Piot (1995–2008) and Michel Sidibé (2009–2019). The agency promotes the GIPA principle (greater involvement of people living with HI ...

HIV/AIDS By Country
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 child during ...
