The Joint United Nations Programme on HIV and AIDS is the main advocate for accelerated, comprehensive and coordinated global action on the HIV/AIDS pandemic.
World AIDS Day, designated on 1 December every year since 1988, is an international day dedicated to raising awareness of the AIDS pandemic caused by the spread of HIV infection and mourning those who have died of the disease. The acquired immunodeficiency syndrome (AIDS) is a life-threatening condition caused by the human immunodeficiency virus (HIV). The HIV virus attacks the immune system of the patient and reduces its resistance to other diseases. Government and health officials, non-governmental organizations, and individuals around the world observe the day, often with education on AIDS prevention and control.
HIV/AIDS originated in the early 20th century and has become a major public health concern and cause of death in many countries. AIDS rates varies significantly between countries, with the majority of cases 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 – approximately 35 million people – were Africans, of whom around 1 million have already died. Eastern and Southern Africa alone accounted for an estimate of 60 percent of all people living with HIV and 100 percent of all AIDS deaths in 2011. The countries of Eastern and Southern Africa are most affected, leading to raised death rates and lowered life expectancy among adults between the ages of 20 and 49 by about twenty years. Furthermore, 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 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.
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.
The population of Africa has grown rapidly over the past century and consequently shows a large youth bulge, further reinforced by a low life expectancy of below 50 years in some African countries. Total population as of 2024 is about 1.5 billion, with a growth rate of about 100 million every three years. The total fertility rate for Africa is 4.7 as of 2018, the highest in the world according to the World Bank. The most populous African country is Nigeria with over 206 million inhabitants as of 2020 and a growth rate of 2.6% p.a.

The Global Media AIDS Initiative (GMAI) is an umbrella organization that unites and motivates media companies around the world to use their influence, resources, and creative talent to address AIDS. The GMAI creates a framework for sharing television and radio programming among media companies in order to increase public health messaging. The organization also educates journalists, editors and producers on how to cover the issue. HIV is preventable, and GMAI members aim to improve public awareness and knowledge to help stem the spread of HIV/AIDS.
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 was first detected in Canada in 1982. In 2018, there were approximately 62,050 people living with HIV/AIDS in Canada. It was estimated that 8,300 people were living with undiagnosed HIV in 2018. Mortality has decreased due to medical advances against HIV/AIDS, especially highly active antiretroviral therapy (HAART).
The current population of Myanmar is 54.05 million. It was 27.27 million in 1970. The general state of healthcare in Myanmar is poor. The military government of 1962-2011 spent anywhere from 0.5% to 3% of the country's GDP on healthcare. Healthcare in Myanmar is consistently ranked among the lowest in the world. In 2015, in congruence with a new democratic government, a series of healthcare reforms were enacted. In 2017, the reformed government spent 5.2% of GDP on healthcare expenditures. Health indicators have begun to improve as spending continues to increase. Patients continue to pay the majority of healthcare costs out of pocket. Although, out of pocket costs were reduced from 85% to 62% from 2014 to 2015. They continue to drop annually. The global average of healthcare costs paid out of pocket is 32%. Both public and private hospitals are understaffed due to a national shortage of doctors and nurses. Public hospitals lack many of the basic facilities and equipment. WHO consistently ranks Myanmar among the worst nations in healthcare.
Health in the Central African Republic has been degraded by years of internal conflict and economic turmoil since independence from France in 1960. One sixth of the country's population is in need of acute medical care. Endemic diseases put a high demand on the health infrastructure, which requires outside assistance to sustain itself.
North Korea has a life expectancy of 72 years as of 2020. While North Korea is classified as a low-income country, the structure of North Korea's causes of death (2013) is unlike that of other low-income countries. Rather, causes of death are closer to the worldwide averages, with non-communicable diseases – such as cardiovascular disease – accounting for two-thirds of the total deaths.
The health status of Namibia has increased steadily since independence, and the government does have focus on health in the country and seeks to make health service upgrades. As a guidance to achieve this goal, the Institute for Health Metrics and Evaluation (IHME) and World Health Organization (WHO) recently published the report "Namibia: State of the Nation's Health: Findings from the Global Burden of Disease." The report backs the fact that Namibia has made steady progress in the last decades when it comes to general health and communicable diseases, but despite this progress, HIV/AIDS still is the major reason for low life expectancy in the country.
