).

Since AIDS was first recognized in 1981, it has led to the deaths of more than 25 million people, making it one of the most destructive diseases in recorded history.

Despite recent improved access to antiretroviral treatment and care in many regions of the world, in 2007 the AIDS pandemic killed an estimated 2.1 million people, including 330,000 children. As of 2009, it is estimated that there are 33.3 million people worldwide living with HIV/AIDS, with 2.6 million new HIV

. This has been attributed to lack of access to antiretroviral treatment in huge areas such as the continent of Africa, where, according to French researcher Olivier Schwartz, less than 10 percent of infected are reported to have access to it.

According to some researchers and institutions the situation is more serious than the UNAIDS figures suggest, the epidemic is accelerating and a second wave is developing (2002 report). It has also been claimed that UNAIDS has historically overstated the AIDS pandemic and that the postulated second wave will not occur.

 has been elucidated by studies of the HIV genome, which indicate that the most common type of HIV (HIV-1) originated in chimpanzees.

Regions with large infected populations

The pandemic is not homogeneous within regions, with some countries more afflicted than others. Even at the country level, there are wide variations in infection levels between different areas. The number of people infected with HIV continues to rise in most parts of the world, despite the implementation of prevention strategies, Sub-Saharan Africa being by far the worst-affected region, with an estimated 22.5 million at the end of 2007, 68% of the global total. South and South East Asia have an estimated 12% of the global total.

Several countries reportedly have prevalence rates around 2 to 3%, and no country has rates above 10%. In Nigeria and Côte d'Ivoire, two of the region's most populous countries, between 5 and 7% of adults are reported to carry the virus.

Across Sub-Saharan Africa, more women are infected with HIV than men, with 13 women infected for every 10 infected men. This gender gap continues to grow. Throughout the region, women are being infected with HIV at earlier ages than men. The differences in infection levels between women and men are most pronounced among young people (aged 15–24 years). In this age group, there are 36 women infected with HIV for every 10 men. The widespread prevalence of sexually transmitted disease

Mother-to-child transmission is another contributing factor in the transmission of HIV-1 in developing nations. Due to a lack of testing, a shortage in antenatal therapies and through the feeding of contaminated breast milk, 590,000 infants born in developing countries are infected with HIV-1 per year.

 contribute to high rates of infection. In some African countries, 25% or more of the working adult population is HIV-positive. Poor economic conditions caused by slow onset-emergencies, such as drought, or rapid onset natural disasters and conflict can result in young women and girls being forced into using sex as a survival strategy. Worse still, research indicates that as emergencies, such as drought, take their toll and the number of potential 'clients' decreases, women are forced by clients to accept greater risks, such as not using contraceptives.

 and some of his political allies notably questioned the connection between HIV and AIDS, stating instead that factors such as undernourishment caused AIDS. Critics charge that the AIDS denialist policies of Mbeki's administration impeded the creation of effective programs for distribution of antiretroviral drugs, causing thousands of unnecessary deaths. UNAIDS estimates that in 2005 there were 5.5 million people in South Africa infected with HIV — 12.4% of the population. This was an increase of 200,000 people since 2003.

Middle East and North Africa

HIV/AIDS prevalence in the Middle East and North Africa is around 0.2% (0.1–0.7%), with between 230,000 and 1.4 million people infected. Among young people 15–24 years of age, 0.3% of women [0.1–0.8%] and 0.17% of men [0.1–0.3%] were living with HIV infection by the end of 2004.

South and South-East Asia

The HIV prevalence rate in South and South-East Asia is less than 0.35 percent, with total of 4.2 – 4.7 million adults and children infected. More AIDS deaths (480,000) occur in this region than in any other except sub-Saharan Africa. The geographical size and human diversity of South and South-East Asia have resulted in HIV epidemics differing across the region. The AIDS picture in South Asia is dominated by the epidemic in India

East Asia

The national HIV prevalence levels in East Asia is 0.1% in the adult (15–49) group. However, due to the large populations of many East Asian nations, this low national HIV prevalence still means that large numbers of people are infected with HIV. The picture in this region is dominated by China. Much of the current spread of HIV in China is through injecting drug use and paid sex. In China

Caribbean

The Caribbean is the second-most affected region in the world. Among adults aged 15–44, AIDS has become the leading cause of death. The region's adult prevalence rate is 1.6% with national rates ranging from 0.2% to 2.7%. HIV transmission occurs largely through heterosexual intercourse, with two thirds of AIDS cases in this region attributed to this route. Sex between men is also a significant route of transmission, even though it is heavily stigmatised and illegal in many areas. HIV transmission through injecting drug use remains rare, except in Bermuda and Puerto Rico.

United States and Canada

The adult prevalence rate in this region is 0.7% with over 1 million people currently infected with HIV. In the United States from 2001–2005, the highest transmission risk behaviors were sex between men (40–49% of new cases) and high risk heterosexual sex (32–35% of new cases). Currently, rates of HIV infection in the US are highest in the eastern and southern regions, with the exception of California

. Currently, 35,000–40,000 new infections occur in the USA every year. AIDS is one of the top three causes of death for African American men aged 25–54 and for African American women aged 35–44 years in the United States of America. In the United States, African Americans make up about 48% of the total HIV-positive population and make up more than half of new HIV cases, despite making up only 12% of the population. The main route of transmission for women is through unprotected heterosexual sex. African American women are 19 times more likely to contract HIV than other women. Experts attribute this to "AIDS fatigue" among younger people who have no memory of the worst phase of the epidemic in the 1980s and early 1990s, as well as "condom fatigue

 also had growing numbers of infected people, with estimates of 500,000 and 3,700 respectively in 2004. The epidemic is still in its early stages in this region, which means that prevention strategies may be able to halt and reverse this epidemic. However, transmission of HIV is increasing through sexual contact and drug use among the young (<30 years). Indeed, over 80% of current infections occur in this region in people less than 30 years of age.

Western Europe

In most countries of Western Europe, AIDS cases have fallen to levels not seen since the original outbreak; many attribute this trend to aggressive educational campaigns, screening of blood transfusions and increased use of condoms. Also, the death rate from AIDS in Western Europe has fallen sharply, as new AIDS therapies have proven to be an effective (though expensive) means of suppressing HIV.

In this area, the routes of transmission of HIV is diverse, including paid sex, injecting drug use, mother to child, male with male sex and heterosexual sex. However, many new infections in this region occur through contact with HIV-infected individuals from other regions. The adult (15–49) prevalence in this region is 0.3% with between 570,000 and 890,000 people currently infected with HIV infection. Due to the availability of antiretroviral therapy, AIDS deaths have stayed low since the lows of the late 1990s. However, in some countries, a large share of HIV infections remain undiagnosed and there is worrying evidence of antiretroviral drug resistance among some newly HIV-infected individuals in this region.

Oceania

There is a very large range of national situations regarding AIDS and HIV in this region. This is due, in part, to the large distances between the islands of Oceania. The wide range of development in the region also plays an important role. The prevalence is estimated at between 0.2% and 0.7%, with between 45,000 and 120,000 adults and children currently infected with HIV.

Papua New Guinea has one of the most serious AIDS epidemics in the region. According to UNAIDS, HIV cases in the country have been increasing at a rate of 30 percent annually since 1997, and the country's HIV prevalence rate in late 2006 was 1.3%.
