The AIDS epidemic, caused by HIV, found its way to the United States between the 1970s and 1980s, but 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. Treatment of HIV/AIDS is primarily via the use of multiple antiretroviral drugs, and education programs to help people avoid infection.
HIV/AIDS originated in Africa during the early 20th century and has been a major public health concern and cause of death in many African countries. AIDS rates varies significantly between countries, though the majority of cases are concentrated in Southern Africa. Although the continent is home to about 15.2 percent of the world's population, more than two-thirds of the total population infected worldwide – some 35 million people – were Africans, of whom 15 million have already died. Eastern and Southern Africa alone accounted for an estimate of 60 percent of all people living with HIV and 70 percent of all AIDS deaths in 2011. The countries of Eastern and Southern Africa are most affected, AIDS has raised death rates and lowered life expectancy among adults between the ages of 20 and 49 by about twenty years. Furthermore, the life expectancy in many parts of Africa is declining, largely as a result of the HIV/AIDS epidemic with life-expectancy in some countries reaching as low as thirty-nine years.
HIV/AIDS has been a public health concern for Latin America due to a remaining prevalence of the disease. In 2018 an estimated 2.2 million people had HIV in Latin America and the Caribbean, making the HIV prevalence rate approximately 0.4% in Latin America.
HIV/AIDS in India is an epidemic. The National AIDS Control Organisation (NACO) estimated that 2.14 million people lived with HIV/AIDS in India in 2017. Despite being home to the world's third-largest population of persons with HIV/AIDS, the AIDS prevalence rate in India is lower than that of many other countries. In 2016, India's AIDS prevalence rate stood at approximately 0.30%—the 80th highest in the world. Treatment of HIV/AIDS is primarily via a "drug cocktail" of antiretroviral drugs and education programs to help people avoid infection.
AIDS service organizations are community-based organizations that provide support for people affected by HIV/AIDS. This article focuses on HIV/AIDS service organizations in the United States only.
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.
Angola has a large HIV/AIDS infected population, however, it has one of the lowest prevalence rates in the Southern Africa zone. The status of the HIV/AIDS epidemic in Angola is expected to change within the near future due to several forms of behavioral, cultural, and economic characteristics within the country such as lack of knowledge and education, low levels of condom use, the frequency of sex and number of sex partners, economic disparities and migration. There is a significant amount of work being done in Angola to combat the epidemic, but most aid is coming from outside of the country.
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 in Lesotho constitutes a very serious threat to Basotho and to Lesotho's economic development. Since its initial detection in 1986, HIV/AIDS has spread at alarming rates in Lesotho. In 2000, King Letsie III declared HIV/AIDS a natural disaster. According to the Joint United Nations Programme on HIV/AIDS (UNAIDS) in 2016, Lesotho's adult prevalence rate of 25% is the second highest in the world, following Eswatini.
HIV/AIDS in Eswatini was first reported in 1986 but has since reached epidemic proportions. As of 2016, Eswatini had the highest prevalence of HIV among adults aged 15 to 49 in the world (27.2%).
As of 2012, approximately 1,100,000 people in Malawi are HIV-positive, which represents 10.8% of the country's population. Because the Malawian government was initially slow to respond to the epidemic under the leadership of Hastings Banda (1966–1994), the prevalence of HIV/AIDS increased drastically between 1985, when the disease was first identified in Malawi, and 1993, when HIV prevalence rates were estimated to be as high as 30% among pregnant women. The Malawian food crisis in 2002 resulted, at least in part, from a loss of agricultural productivity due to the prevalence of HIV/AIDS. Various degrees of government involvement under the leadership of Bakili Muluzi (1994–2004) and Bingu wa Mutharika (2004–2012) resulted in a gradual decline in HIV prevalence, and, in 2003, many people living in Malawi gained access to antiretroviral therapy. Condoms have become more widely available to the public through non-governmental organizations, and more Malawians are taking advantage of HIV testing services.
Mozambique is a country particularly hard-hit by the HIV/AIDS epidemic. According to 2008 UNAIDS estimates, this southeast African nation has the 8th highest HIV rate in the world. With 1,600,000 Mozambicans living with HIV, 990,000 of which are women and children, Mozambique's government realizes that much work must be done to eradicate this infectious disease. To reduce HIV/AIDS within the country, Mozambique has partnered with numerous global organizations to provide its citizens with augmented access to antiretroviral therapy and prevention techniques, such as condom use. A surge toward the treatment and prevention of HIV/AIDS in women and children has additionally aided in Mozambique's aim to fulfill its Millennium Development Goals (MDGs). Nevertheless, HIV/AIDS has made a drastic impact on Mozambique; individual risk behaviors are still greatly influenced by social norms, and much still needs to be done to address the epidemic and provide care and treatment to those in need.
Rwanda faces a generalized epidemic, with an HIV prevalence rate of 3.1 percent among adults ages 15 to 49. The prevalence rate has remained relatively stable, with an overall decline since the late 1990s, partly due to improved HIV surveillance methodology. In general, HIV prevalence is higher in urban areas than in rural areas, and women are at higher risk of HIV infection than men. Young women ages 15 to 24 are twice as likely to be infected with HIV as young men in the same age group. Populations at higher risk of HIV infection include people in prostitution and men attending clinics for sexually transmitted infections.
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.
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%.
HIV/AIDS in Jamaica has a 1.5 percent prevalence of the adult population estimated to be HIV-positive. There has been no significant change over the last five years and therefore Jamaica appears to have stabilized its HIV/AIDS epidemic.
Nicaragua has 0.2 percent of the adult population estimated to be HIV-positive. Nicaragua has one of the lowest HIV prevalence rates in Central America.
With less than 1 percent of the population estimated to be HIV-positive, Egypt is a low-HIV-prevalence country. However, between the years 2006 and 2011, HIV prevalence rates in Egypt increased tenfold. Until 2011, the average number of new cases of HIV in Egypt was 400 per year. But, in 2012 and 2013 it increased to about 600 new cases and in 2014 it reached 880 new cases per year. According to UNAIDS 2016 statistics, there are about 11,000 people currently living with HIV in Egypt. The Ministry of Health and Population reported in 2020 over 13,000 Egyptians are living with HIV/AIDS. However, unsafe behaviors among most-at-risk populations and limited condom usage among the general population place Egypt at risk of a broader epidemic.
Discrimination against people with HIV/AIDS or serophobia is the prejudice, fear, rejection, and stigmatization of people with HIV/AIDS. Marginalized, at-risk groups such as members of the LGBTQ+ community, intravenous drug users, and sex workers are most vulnerable to facing HIV/AIDS discrimination. The consequences of societal stigma against PLHIV are quite severe, as HIV/AIDS discrimination actively hinders access to HIV/AIDS screening and care around the world. Moreover, these negative stigmas become used against members of the LGBTQ+ community in the form of stereotypes held by physicians.
South Africa's HIV/AIDS epidemic, which is among the most severe in the world, is concentrated in its townships, where many black South Africans live due to the lingering effects of the Group Areas Act.
