HIV/AIDS worldwide - Statistics & Facts
The Human Immunodeficiency Virus (HIV), is a virus that causes Acquired Immunodeficiency Syndrome (AIDS). AIDS is a condition that leads to the continuous deterioration of the immune system which can ultimately result in death. HIV is passed on primarily through the transmission of an infected person’s blood, unprotected sexual intercourse, and injected drug use.
However, after a peak in 2004-2005, the number of AIDS deaths worldwide has been steadily decreasing. Still, there were approximately 630,000 AIDS-related deaths all over the world in 2022, with most of them once again occurring in Sub-Saharan Africa. With around 48,000, Mozambique had by far the highest number of deaths due to AIDS that year.
As expected, spending on HIV/AIDS is a very important issue. In 2022, available funding for the battle against the disease totaled around 20.8 billion U.S. dollars globally. However, this will have to rise steeply with some estimates placing the funds required by 2025 at 29 billion. Poorer countries mainly depend on international funding to stem the HIV/AIDS epidemic. For example, public and philanthropic institutions from developed countries are among the top funders for research and development on HIV/AIDS.
Which countries are most impacted by HIV/AIDS?
In 2020, around 39 million people were HIV positive worldwide. About 20.8 million of those infected with HIV lived in Eastern and Southern Africa. In fact, of the 25 countries with the highest HIV prevalence in 2022, all were in Africa. HIV prevalence in North America and Europe is significantly lower than in other regions, which can be attributed to better awareness, higher hygiene standards, greater access to health care, and widespread HIV prevention.However, after a peak in 2004-2005, the number of AIDS deaths worldwide has been steadily decreasing.

HIV/AIDS treatment and funding
Since its discovery in 1981, treatment for HIV/AIDS has vastly improved. With the help of antiretroviral therapy (ART), people infected with HIV can effectively stall the progress from HIV to AIDS. Although access to antiretroviral therapy in many countries is still limited, progress over the last few years can be clearly seen.As expected, spending on HIV/AIDS is a very important issue.
