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%. [1] As of 2019, 0.6% of Cambodian adults currently has the virus.
Cambodia's HIV/AIDS epidemic is spread primarily through heterosexual transmission and revolves largely around the sex trade. HIV transmission occurs mainly in sexual partnerships where one partner has engaged in high-risk behaviors. Women constitute a growing share of people living with HIV/AIDS, comprising an estimated 47 percent of people living with HIV/AIDS in 2003, compared with 37 percent in 1998. [1]
This increased proportion of infections among women may reflect declining prevalence rates among males, as well as deaths among males infected in the early years of Cambodia's epidemic. Significantly, a low prevalence rate in the general population masks far higher prevalence rates in certain sub-populations, such as injecting drug users, people in prostitution, men who have sex with men, karaoke hostesses and beer girls, and mobile and migrant populations. [1]
By 2014, HIV prevalence was reduced to 0.4 percent through a successful prevention program. However, in 2015 a massive outbreak of HIV stemming mostly from Roka occurred. The cause is thought to be the reuse of syringes by an unlicensed doctor operating in the region who has since been jailed. [2]
After the first case of HIV was detected in Cambodia in 1991, the prevalence of infection increased steadily to a high of 2 percent in 1998. In the general population, the prevalence declined to 0.5 percent in 2009, down from 1.2 percent in 2001. The prevalence of HIV infection among women visiting antenatal care (ANC) clinics also declined, from a high of 2.1 percent in 1999 to 1.1 percent in 2006. [1]
Among HIV-infected pregnant women, there was also a gradual increase in the percentage who received antiretroviral therapy (ART) to reduce the risk of mother-to-child transmission, from 1.2 percent in 2003 to 11.2 percent in 2007 to 32.3 percent in 2009 and it is still increasing. [1]
The global pandemic of HIV/AIDS began in 1981, and is an ongoing worldwide public health issue. According to the World Health Organization (WHO), by 2023, HIV/AIDS had killed approximately 40.4 million people, and approximately 39 million people were infected with HIV globally. Of these, 29.8 million people (75%) are receiving antiretroviral treatment. There were about 630,000 deaths from HIV/AIDS in 2022. 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.
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.
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.
The Philippines has one of the lowest rates of infection of HIV/AIDS, 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.
The southeast-Asian nation of East Timor has dealt with HIV/AIDS since its first documented case in 2001. It has one of the lowest HIV/AIDS-prevalence rates in the world.
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.
HIV/AIDS in Bolivia has a less than 1 percent prevalence of Bolivia's adult population estimated to be HIV-positive. Bolivia has one of the lowest HIV prevalence rates in the Latin America and Caribbean region.
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 web|url=http://www.avert.org/caribbean-hiv-aids-statistics.htm |title=Caribbean HIV & AIDS Statistics|date=21 July 2015}}</ref> 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. There has been 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).
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 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 after Thailand, Cambodia, and Burma 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.
