HIV/AIDS originated in Africa during early 20th century and is 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 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.
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.
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.
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 prevalence of circumcision is the percentage of males in a given population who have been circumcised, with the procedure most commonly being performed as a part of prophylactic healthcare, a religious obligation, or cultural practice. Yosha & Bolnick & Koyle (2012) states that the global incidence of circumcision has risen and seems likely to continue to do so during the "first half of the twenty-first century".
As for many developing countries, health issues in Iran stem from a variety of reasons: namely, water and sanitation, diet and fitness, various addictions, mental fitness, communicable diseases, hygiene and the environment.
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.
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.
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.
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.
