Human immunodeficiency virus, HIV, targets cells that assist the human body’s ability to fight off infection, thus weakening the resistance of the immune system. HIV can cause acquired immunodeficiency syndrome, AIDS, if not properly treated. This means that a person is vulnerable to numerous fatal diseases and disorders.
Antiretroviral therapy (ART) is a highly effective treatment for HIV that involves adhering to a prescribed medication regimen under the guidance of a healthcare provider.
When taken consistently and as directed, ART can suppress the viral load in the body to undetectable levels, meaning that the virus is no longer detectable by standard tests.
ART is available in two main forms: oral pills and long-acting injectable treatments.
Currently, there is no HIV treatment that completely cures the condition which means that if someone has HIV, it will remain in the body for that person’s entire life. However, the majority of HIV-positive people can live long, healthy lives thanks to extremely effective pharmaceutical treatments.

Based on the latest data from the World Health Organization, approximately 40.8 million HIV-infected people had been registered by the end of 2024:
At the same time, the share of people who undergo testing, treatment, and viral load suppression registered a considerable increase:
The data for 2024 shows that 31.6 million, or 77% [62 – 90%] of HIV-positive people were undergoing antiretroviral therapy:

To meet the 95-95-95 objective for testing, treatment, and viral suppression, another 3.2 million people living with HIV must be aware of their HIV status.

In its report, the World Health Organization explained that cuts to foreign assistance can potentially undo years of progress. Namely, between 2025 and 2029, the number of HIV-related deaths could increase by 4 million from the 630,000 registered in 2024, while the number of new infections could exceed 6 million.
In 2023, of all new HIV infections, 44% was attributed to women and girls, according to UNAIDS.
In terms of the AIDS-related mortality rate, since 2010, this has fallen by 58% among women and girls whereas among males, this figure has declined by 50%.
At the same time, some concerning data has been provided by UNAIDS regarding sub-Saharan Africa, where experts have observed a 62% rise in new infections among women and girls.
UNAIDS also outlines that women and girls of every generation make up 63% of all new HIV infections in the same African regions.
On a global scale, around 4,000 weekly HIV infections were registered among females aged 15 to 24, with most – 3,300 – occurring in sub-Saharan Africa.
The lives of more than 18 million HIV-infected people were saved between 2000 and 2021 thanks to ART. In addition, the treatment formula led to a 39% drop in new HIV infections and a staggering 51% decrease in fatalities linked with the virus.
In 2023, advances towards meeting the 95-95-95 objectives for HIV testing, treatment, and viral suppression varied. These targets are defined as:
The latest WHO data (as of 2024) shows that the global figures are currently at: 87-77-73.
The estimated total of HIV-related fatalities, all ages, 2010, 2023, 2024
The estimated total of people with HIV, all ages, 2010,2023, 2024
*In 2024, there was no publicly available information on the number of people diagnosed or virally suppressed due to a lack of the latest modelled estimations from several nations.
The data on newly infected cases has been taken from the WHO’s HIV/AIDS surveillance in Europe report.
Sub-Saharan Africa exhibits the highest rates of HIV globally, with Eswatini, South Africa, and Lesotho leading in the number of adults infected with the virus, according to 2024 data from the World Bank.
HIV prevalence (% of population ages 15-49)
In Eswatini, HIV is the major cause of death, affecting around 23.4% of the population based on the WB data, although according to Doctors Without Borders, this figure is as high as 25%.
Around 30% of women between 15 and 49 are infected with HIV, and social stigma exacerbates the issue, which leads to low uptake of the oral PrEP* with just 11% of eligible individuals taking it.
*Pre-exposure prophylaxis (PrEP) – refers to a pill taken daily by HIV-negative people to avoid HIV acquisition.
The data from UNAIDS shows that there are 220,000 people in a country of 1.2 million living with HIV, but the good news is that the coverage of people receiving ART is 94%.
Although the country has made significant progress regarding the issue (in the period 2011-2016 the rate of newly-infected citizens was cut by half), HIV remains a key problem.
Together with various organizations, the government is attempting to tackle the issue by increasing access to HIV testing and subsequent treatment. It is of note that those most affected are sex workers, with over 60.5% being HIV-positive.
According to Spotlight – a prominent health-journalism media outlet in South Africa – the number of HIV-positive individuals has for the first time reached 8 million people (around 12.8% of the country’s population), with roughly 6.2 million being on treatment.
Latest estimations showed:
More people are undergoing ART, which has increased life expectancy, and more people with HIV are beginning to live longer lives.
Around 270,000 individuals in this nation of 2.3 – 2.4 million people are living with HIV, according to Lesotho’s National HIV Estimates report of July 2024.
HIV prevalence among adults is 17.1% according to the WB data, while data from the report shows a figure of 18.5%, the second-highest in the world.
Based on the National HIV estimates Report, 4,800 new HIV infections were registered in 2023, which represents a 6% decline from 2022, and a decrease of over 60% compared to the 2004 peak, when this figure hit 24,500.
For the fiscal year 2024-2025, the Government of Lesotho has dedicated 233 million Maloti (about US$15 million) for ART procurement, confirming the nation’s commitment to tackling the HIV-related issue.
To safeguard our well-being and reduce the stigma associated with HIV and AIDS, it is essential to carry out awareness-raising activities around the globe. Moreover, increased accessibility to diagnosis and treatment (especially in the most vulnerable nations) is crucial to decreasing the rate of AIDS-related deaths.
