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.
The global epidemic of HIV/AIDS 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 antiretroviral treatment. There were about 770,000 deaths from HIV/AIDS in 2018, and 650,000 deaths in 2021. 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.
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.
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.
HIV is recognized as a health concern in Pakistan with the number of cases growing. Moderately high drug use and lack of acceptance that non-marital sex is common in the society have allowed the HIV epidemic to take hold in Pakistan, mainly among injecting drug users (IDU), male, female and transvestite sex workers as well as the repatriated migrant workers. HIV infection can lead to AIDS that may become a major health issue.
The very high rate of HIV infection experienced in Uganda during the 1980s and early 1990s created an urgent need for people to know their HIV status. The only option available to them was offered by the National Blood Transfusion Service, which carries out routine HIV tests on all the blood that is donated for transfusion purposes. The great need for testing and counseling resulted in a group of local non-governmental organizations such as The AIDS Support Organisation (TASO), Uganda Red Cross, Nsambya Home Care, the National Blood Bank, the Uganda Virus Research Institute together with the Ministry of Health establishing the AIDS Information Centre in 1990. This organization worked to provide HIV testing and counseling services with the knowledge and consent of the client involved.
Since the first HIV/AIDS case in the Lao People's Democratic Republic (PDR) was identified in 1990, the number of infections has continued to grow. In 2005, UNAIDS estimated that 3,700 people in Lao PDR were living with HIV.
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.
The number of adults and children living with HIV/AIDS in Benin in 2003 was estimated by the Joint United Nations Programme for HIV/AIDS (UNAIDS) to range between 38,000 and 120,000, with nearly equal numbers of males and females. A recent study conducted by the National AIDS Control Program estimated the number of people living with HIV/AIDS to be 71,950. In 2003, an estimated 6,140 adults and children died of AIDS. Benin has a well-functioning system of antenatal HIV surveillance; in 2002, the median HIV prevalence at 36 antenatal clinics was 1.9%. Another study in 2002 showed an overall prevalence of 2.3% among adults in Cotonou, Benin's largest city.
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%).
HIV/AIDS in Nigeria was a concern in the 2000s, when an estimated seven million people had HIV/AIDS. In 2008, the HIV prevalence rate among adults aged between 15 and 49 was 3.9 percent, in 2018 the rate among adults aged between 15 and 65 was 1.5 percent. As elsewhere in Africa, women are statistically more likely to have HIV/AIDS. The Nigeria HIV/AIDS Indicator and Impact Survey was the world's largest and presented statistics which showed the overall numbers were lower than expected. Antiretroviral treatment is available, but people prefer to take the therapy secretly, since there is still noticeable discrimination against people with HIV/AIDS.
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.
With less than 0.1 percent of the population estimated to be HIV-positive, Bangladesh is a low HIV-prevalence country.
Cases of HIV/AIDS in Peru are considered to have reached the level of a concentrated epidemic.
The Dominican Republic has a 0.7 percent prevalence rate of HIV/AIDS, among the lowest percentage-wise in the Caribbean region. However, it has the second most cases in the Caribbean region in total, with an estimated 46,000 HIV/AIDS-positive Dominicans as of 2013.
WhizzKids United is a youth HIV / AIDS prevention, care, treatment and support programme that uses football as an educational medium to facilitate healthy behaviour change. The programme is based in Durban, South Africa and is run by Africaid, a registered charity in the United Kingdom and South Africa.
Founded in 1999, Alliance India is a non-governmental organisation operating in partnership with civil society, government and communities to support sustained responses to HIV in India that protect rights and improve health. Complementing the Indian national programme, we build capacity, provide technical support and advocate to strengthen the delivery of effective, innovative, community-based HIV programmes to vulnerable populations: sex workers, men who have sex with men (MSM), transgender people, hijras, people who inject drugs (PWID), and people living with HIV.
