The global pandemic of HIV/AIDS began in 1981, and is an ongoing worldwide public health issue. According to the World Health Organization (WHO), by 2023, HIV/AIDS had killed approximately 40.4 million people, and approximately 39 million people were infected with HIV globally. Of these, 29.8 million people (75%) are receiving antiretroviral treatment. There were about 630,000 deaths from HIV/AIDS in 2022. The 2015 Global Burden of Disease Study estimated that the global incidence of HIV infection peaked in 1997 at 3.3 million per year. Global incidence fell rapidly from 1997 to 2005, to about 2.6 million per year. Incidence of HIV has continued to fall, decreasing by 23% from 2010 to 2020, with progress dominated by decreases in Eastern Africa and Southern Africa. As of 2020, there are approximately 1.5 million new infections of HIV per year globally.
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.
Tanzania faces generalized HIV epidemic which means it affects all sections of the society but also concentrated epidemic among certain population groups. The prevalence of HIV/AIDS in Tanzania is characterised by substantial across age, gender, geographical location and socioeconomic status implying difference in the risk of transmission of infection. In 2019, among 1.7 million people living with HIV/AIDS, the prevalence was 4.6% and 58,000 new HIV infection among 15–49 years old, and 6,500 new infections among children below 15 years old, 50% of all new infections are between 15 - 29 years of age group. Report from Tanzania PHIA of 2016/17 shows that HIV prevalence among women is higher (6.2%) than men (3.1%). The prevalence of HIV is less than 2% among 15-19 years for both males and females and then increases with age for both sexes.
In 2008, 4.7 million people in Asia were living with human immunodeficiency virus (HIV). Asia's epidemic peaked in the mid-1990s, and annual HIV incidence has declined since then by more than half. Regionally, the epidemic has remained somewhat stable since 2000.
The Caribbean is the second-most affected region in the world in terms of HIV prevalence rates. Based on 2009 data, about 1.0 percent of the adult population is living with the disease, which is higher than any other region except Sub-Saharan Africa. Several factors influence this epidemic, including poverty, gender, sex tourism, and stigma. HIV incidence in the Caribbean declined 49% between 2001 and 2012. Different countries have employed a variety of responses to the disease, with a range of challenges and successes.
In Western Europe, the routes of transmission of HIV are diverse, including paid sex, sex between men, intravenous drugs, mother to child transmission, and heterosexual sex. However, many new infections in this region occur through contact with HIV-infected individuals from other regions. In some areas of Europe, such as the Baltic countries, the most common route of HIV transmission is through injecting drug use and heterosexual sex, including paid sex.
HIV/AIDS is one of the most serious health concerns in South Africa. The country has the highest number of people afflicted with HIV of any country, and the fourth-highest adult HIV prevalence rate, according to the 2019 United Nations statistics.
The Democratic Republic of the Congo was one of the first African countries to recognize HIV, registering cases of HIV among hospital patients as early as 1983.
Like other countries worldwide, HIV/AIDS is present in Ghana. As of 2014, an estimated 150,000 people infected with the virus. HIV prevalence is at 1.37 percent in 2014 and is highest in the Eastern Region of Ghana and lowest in the northern regions of the country. In response to the epidemic, the government has established the Ghana AIDS Commission which coordinates efforts amongst NGO's, international organizations and other parties to support the education about and treatment of aids throughout Ghana and alleviating HIV/AIDS issues in Ghana.
HIV/AIDS is considered the deadliest epidemic in the 21st century. It is transmitted through sex, intravenous drug use and mother-to-child transmission. Zambia is experiencing a generalized HIV/AIDS epidemic, with a national HIV prevalence rate of 11.3% among adults ages 15 to 49 as of 2018. Per the 2000 Zambian census, the people affected by HIV/AIDS constituted 15% of the total population, amounting to one million, of which 60% were women. The pandemic results in increased number of orphans, with an estimated 600,000 orphans in the country. It was prevalent more in urban areas compared to rural and among all provinces, Copperbelt Province and Lusaka Province had higher occurrence.
UNAIDS has said that HIV/AIDS in Indonesia is one of Asia's fastest growing epidemics. In 2010, it is expected that 5 million Indonesians will have HIV/AIDS. In 2007, Indonesia was ranked 99th in the world by prevalence rate, but because of low understanding of the symptoms of the disease and high social stigma attached to it, only 5-10% of HIV/AIDS sufferers actually get diagnosed and treated. According to the a census conducted in 2019, it is counted that 640,443 people in the country are living with HIV. The adult prevalence for HIV/ AIDS in the country is 0.4%. Indonesia is the country in Southeast Asia to have the most number of recorded people living with HIV while Thailand has the highest adult prevalence.
The first HIV/AIDS cases in Nepal were reported in 1988. The HIV epidemic is largely attributed to sexual transmissions and account for more than 85% of the total new HIV infections. Coinciding with the outbreak of civil unrest, there was a drastic increase in the new cases in 1996. The infection rate of HIV/AIDS in Nepal among the adult population is estimated to be below the 1 percent threshold which is considered "generalized and severe". However, the prevalence rate masks a concentrated epidemic among at-risk populations such as female sex workers (FSWs), male sex workers (MSWs), injecting drug users (IDUs), men who have sex with men (MSM), Transgender Groups (TG), migrants and male labor migrants (MLMs) as well as their spouses. Socio-Cultural taboos and stigmas that pose an issue for open discussion concerning sex education and sex habits to practice has manifest crucial role in spread of HIV/AIDS in Nepal. With this, factors such as poverty, illiteracy, political instability combined with gender inequality make the tasks challenging.
Since HIV/AIDS was first reported in Thailand in 1984, 1,115,415 adults had been infected as of 2008, with 585,830 having died since 1984. 532,522 Thais were living with HIV/AIDS in 2008. In 2009 the adult prevalence of HIV was 1.3%. As of 2016, Thailand had the highest prevalence of HIV in Southeast Asia at 1.1 percent, the 40th highest prevalence of 109 nations.
Honduras is the Central American country most adversely affected by the HIV/AIDS epidemic. It is estimated that the prevalence of HIV among Honduran adults is 1.5%.
The HIV/AIDS epidemic in Ukraine is one of the fastest-growing epidemics in the world. Ukraine has one of the highest rates of increase of HIV/AIDS cases in Eastern Europe and highest HIV prevalence outside Africa. Experts estimated in August 2010 that 1.3 percent of the adult population of Ukraine was infected with HIV, the highest in all of Europe. Late 2011 Ukraine numbered 360,000 HIV-positive persons. Between 1987 and late 2012 27,800 Ukrainians died of AIDS. In 2012 tests revealed 57 new cases of HIV positive Ukrainians each day and 11 daily AIDS-related deaths.
Despite big declines, the prevalence of HIV/AIDS in Cambodia is among the highest in Asia. Although Cambodia is one of the poorest countries in the world, extensive HIV prevention and control efforts by the Royal Government of Cambodia and its partners have helped to reduce the spread of HIV. Between 2003 and 2005, the estimated HIV prevalence among Cambodian adults aged 15 to 49 declined by 20%, from 2.0% to 1.6%. As of 2019, 0.6% of Cambodian adults currently has the virus.
Vietnam faces a concentrated HIV epidemic among high-risk groups, including sex workers, and intravenous drug users. There are cases of HIV/AIDS in all provinces of Vietnam, though low testing rates make it difficult to estimate how prevalent the disease is. The known rates among high-risk groups are high enough that there is a risk of HIV/AIDS rates increasing among the general population as well. People who are HIV+ face intense discrimination in Vietnam, which does not offer legal protections to those living with the condition. Stigma, along with limited funding and human research, make the epidemic difficult to control.
Infection rates of HIV/AIDS in Niger are estimated to be under 1%, low in relation to most of Africa and much of the world.
As of 2016, it is estimated that there are 1.5 million adults and children living with HIV/AIDS in North America, excluding Central America and the Caribbean. 70,000 adults and children are newly infected every year, and the overall adult prevalence is 0.5%. 26,000 people in North America die from AIDS every year.
Since reports of emergence and spread of the human immunodeficiency virus (HIV) in the United States between the 1970s and 1980s, the HIV/AIDS epidemic has frequently been linked to gay, bisexual, and other men who have sex with men (MSM) by epidemiologists and medical professionals. It was first noticed after doctors discovered clusters of Kaposi's sarcoma and pneumocystis pneumonia in homosexual men in Los Angeles, New York City, and San Francisco in 1981. The first official report on the virus was published by the Center for Disease Control (CDC) on June 5, 1981, and detailed the cases of five young gay men who were hospitalized with serious infections. A month later, The New York Times reported that 41 homosexuals had been diagnosed with Kaposi's sarcoma, and eight had died less than 24 months after the diagnosis was made.
