HIV/AIDS originated in Africa in the early 20th century and is a major public health concern and cause of death in many African countries. AIDS rates vary 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 estimated 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 680,000 deaths in 2020. 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 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.
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.
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.
Kenya has a severe, generalized HIV epidemic, but in recent years, the country has experienced a notable decline in HIV prevalence, attributed in part to significant behavioral change and increased access to ARV. Adult HIV prevalence is estimated to have fallen from 10 percent in the late 1990s to about 4.8 percent in 2017. Women face considerably higher risk of HIV infection than men but have longer life expectancies than men when on ART. The 7th edition of AIDS in Kenya reports an HIV prevalence rate of eight percent in adult women and four percent in adult men. Populations in Kenya that are especially at risk include injecting drug users and people in prostitution, whose prevalence rates are estimated at 53 percent and 27 percent, respectively. Men who have sex with men (MSM) are also at risk at a prevalence of 18.2%. Other groups also include discordant couples however successful ARV-treatment will prevent transmission. Other groups at risk are prison communities, uniformed forces, and truck drivers.
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.
HIV/AIDS infection in the Philippines might be low but growing fast. The Philippines has one of the lowest rates of infection, yet has one of the fastest growing number of cases worldwide. The Philippines is one of seven countries with growth in number of cases of over 25%, from 2001 to 2009.
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.
Cases of HIV/AIDS in Peru are considered to have reached the level of a concentrated epidemic. According to a population-based survey conducted in Peru’s 24 largest cities in 2002, adult HIV prevalence was estimated to be less than 1 percent. The survey demonstrated that cases are unevenly distributed in the country, affecting mostly young people between the ages of 25 and 34. As of July 2010, the cumulative reported number of persons infected with HIV was 41,638, and there were 26,566 cases of AIDS, according to the Ministry of Health (MOH), and the male/female ratio for AIDS diagnoses in 2009 was 3.02 to 1. The Joint United Nations Program on HIV/AIDS (UNAIDS) estimates 76,000 Peruvians are HIV-positive, meaning that many people at risk do not know their status. There were 3,300 deaths due to AIDS in Peru in 2007, down from 5,600 deaths in 2005.
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.
HIV/AIDS in Jamaica has a 1.5 percent prevalence of the adult population estimated to be HIV-positive and no significant change over the last five years and therefore Jamaica appears to have stabilized its HIV/AIDS epidemic.
In 2016, the prevalence rate of HIV/AIDS in adults aged 15–49 was 0.3%, relatively low for a developing country. This low prevalence has been maintained, as in 2006, the HIV prevalence in Mexico was estimated at around 0.3% as well. The infected population is remains mainly concentrated among high risk populations, men who have sex with other men, intravenous drug users, and commercial sex workers. This low national prevalence is not reflected in the high-risk populations. The prison population in Mexico, faces a fairly similar low rate of around 0.7%. Among the population of prisoners, around 2% are known to be infected with HIV. Sex workers, male and female, face an HIV prevalence of around 7%. Identifying gay men and men who have sex with other men have a prevalence of 17.4%. The highest risk-factor group is identifying transgender people; about 17.4% of this population is known to be infected with HIV. Around 90% of new infections occur by sex-related methods of transmission.. Of these known infected populations, around 60% of living infected people are known to be on anti-retroviral therapy (ART).
With only 0.2 percent of the adult population estimated to be HIV-positive, Nicaragua has one of the lowest HIV prevalence rates in Central America. HIV was first detected in Nicaragua in 1987, after concentrated epidemics had been reported in other Central American nations. The onset of the epidemic was likely delayed by Nicaragua’s 10-year civil war and the U.S.-led economic blockade, both of which left the country isolated for several years. Relative control over commercial sex work, low infection rates among injecting drug users, and a ban on the commercial sale of blood also slowed HIV transmission. However, the country is at risk of a broader epidemic because of social conditions such as multiple sex partners, gender inequality, and widespread poverty. Many people are unaware of their HIV status and could unwittingly spread the disease. UNAIDS estimates Nicaragua has 7,300 HIV-positive people, nearly half of whom were identified over the past three years.
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 13000 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.
With 1.28 percent of the adult population estimated by UNAIDS to be HIV-positive in 2006, Papua New Guinea has one of the most serious HIV/AIDS epidemics in the Asia-Pacific subregion. Although this new prevalence rate is significantly lower than the 2005 UNAIDS estimate of 1.8 percent, it is considered to reflect improvements in surveillance rather than a shrinking epidemic. Papua New Guinea accounts for 70 percent of the subregion's HIV cases and is the fourth country to be classified as having a generalized HIV epidemic.
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.
With an estimated 150,000 people living with HIV/AIDS in 2016, Haiti has the most overall cases of HIV/AIDS in the Caribbean and its HIV prevalence rates among the highest percentage-wise in the region. There are many risk-factor groups for HIV infection in Haiti, with the most common ones including lower socioeconomic status, lower educational levels, risky behavior, and lower levels of awareness regarding HIV and its transmission. However, HIV prevalence in Haiti is largely dropping as a result of a strong AIDS/HIV educational program, support from non-governmental organizations and private donors, as well as a strong healthcare system supported by UNAIDS. Part of the success of Haiti's HIV healthcare system lies in the governmental commitment to the issue, which alongside the support of donations from the Global Fund and President's Emergency Plan For AIDS Relief (PEPFAR), allows the nation to prioritize the issue. Despite the extreme poverty afflicting a large Haitian population, the severe economic impact HIV has on the nation, and the controversy surrounding how the virus spread to Haiti and the United States, Haiti is on the path to provide universal treatment, with other developing nations emulating its AIDS treatment system.
