Africa leads the world in reducing HIV infections

For the first time, most new infections now occur outside the continent

In Summary

• Sub-Saharan Africa has achieved top reduction in HIV cases compared to 2010

• Despite existing gaps, the report offers hope on the path toward 2030 targets

Africa's prevention measures in the fight against new HIV infections are paying off, according to a new report by UN Aids.

Sub-Saharan Africa has achieved the steepest reduction in HIV cases compared to 2010, it says.

“Four countries (Kenya, Malawi, Nepal and Zimbabwe) have reduced their numbers of annual new HIV infections by 75 per cent and are well on track to reach the target of reducing new HIV infections by 90 per cent by 2030,” the authors state.

"For the first time, the number of new HIV infections outside sub-Saharan Africa surpassed the number of new HIV infections in sub-Saharan Africa."

The report, titled 'The Urgency of Now: Aids at a Crossroads', was unveiled on July 22 at the 25th International Aids Conference in Munich. 

New HIV infections have fallen by 39 per cent since 2010 globally, and by 59 per cent in eastern and southern Africa.

However, the report shows that new HIV infections are on the rise in some regions, including in the Middle East and North Africa. Other regions seeing a surge in infections include Eastern Europe, Central Asia and Latin America.

Almost half of the people who acquired HIV in 2023 — 450,000 people of the global 1.3 million new cases — live in the eastern and southern African region.

However, the report acknowledges that the two regions have achieved the steepest decline in new infections since 2010, a 56 per cent decline.

Globally, the steepest declines in numbers of new HIV infections have been among children aged 0–14 years, a trend that is reflective in Africa where “far fewer children aged 0–14 years are acquiring HIV”.

“This trend is due largely to achievements in eastern and southern Africa, where the annual number of children acquiring HIV fell by an estimated 73 per cent between 2010 and 2023,” the authors say.

There is, however, a need to increase intervention efforts in other regions, such as in western and central Africa, where progress has been slower.

Some countries on the continent are proving to be steadfast in creating a blueprint on how to effectively use public sector resources and plan to eliminate vertical infections.

Namibia, for instance, in May received a bronze-tier certification from the WHO for reducing mother-to-child transmission to less than 5 per cent.

The southern African country avoided 28,000 vertical transmissions in the last 20 years, leading to a 70 per cent reduction in vertical transmissions.

Botswana has also in the past (2021) been lauded for being on-track to eliminating mother-to-child transmission of HIV.

Besides the reduction in new transmissions, the report also underscored the success in access to treatment options for existing cases. More patients are now accessing free antiretroviral therapy offered through the public health sector.

“In 2023, almost three in four adults (73per cent [66–81 per cent]) living with HIV globally had a suppressed viral load, a big improvement compared with the 40 per cent [36–45 per cent] in 2015,” the report says.

This has more than halved annual Aids-related deaths, dropping from 1.3 million in 2010 to 630,000 in 2023. In Africa, the eastern and southern African region has seen a 57 per cent drop in the number of Aids-related deaths between 2010 and 2023.

Other regions seeing equally commendable progress in averting deaths include in the western and central African region, where the decline reached 55 per cent in 2023, while Middle East and North Africa saw a 6 per cent decline in Aids-related infections.

Eastern Europe and central Asia witnessed a 34 per cent rise in Aids-related deaths over the period.

While globally the 2025 prevention target goal of having 95 per cent of people at risk of HIV infection having access to and using effective prevention options remains out of reach, the global HIV prevention response is proceeding at an encouraging pace.

In Africa, the availability of diverse prevention methods provides unparalleled flexibility, encouraging individuals to adopt at least one form of prevention.

With more options now than ever before, people can choose the method that best suits their needs, thereby enhancing overall participation in preventive measures.

Condom use remains the most effective low-cost HIV prevention method. Household survey data suggests about 36 per cent of adults in eastern and southern Africa and 25 per cent in western and central Africa used a condom at last sex.

Other recent preventive options gaining ground in Africa include injectable PREP, which was in February 2024 rolled out in Zambia, making it the first country on the continent to authorise its use.

Despite significant progress in preventing new HIV infections, experts are alarmed by the shrinking funding for scaling HIV prevention among the most affected populations.

The report details that in 2023, total resources available for HIV (US$19.8 billion) dropped by 5 per cent from 2022 and were $9.5 billion short of the amount needed by 2025 ($29.3 billion).

According to UNAids executive director Winnie Byanyima, political willingness among leaders is critical as it can “save millions of lives, prevent millions of new HIV infections and ensure that everyone living with HIV can live full, healthy lives.”

“Whether leaders fulfil their pledge to end Aids is a political and financial choice. The time to choose the right path is now,” Byanyima said during the launch of the report.
