New data shows a dramatic decline in childhood HIV infections over the past three decades, with fewer than 5,000 new cases annually in Uganda. However, progress faces threats from funding cuts, and nearly 120,000 children are still infected each year worldwide.
Global efforts to prevent mother-to-child HIV transmission have led to a substantial decline in new childhood infections, with some countries approaching near-elimination levels, but challenges remain as funding cuts threaten to reverse gains.
In Uganda, the number of children infected with HIV at birth has fallen from about 32,000 annually in the mid-1990s to fewer than 5,000 today, thanks to widespread testing and antiretroviral therapies. These interventions make the virus virtually untransmittable during pregnancy, childbirth, and breastfeeding.
Despite this progress, approximately 120,000 children worldwide are still newly infected with HIV each year, mostly during pregnancy or early childhood. Many of these children die before age four, with an estimated 75,000 annual AIDS-related child deaths. The progress is uneven, and many families lack access to testing and treatment, especially amid recent reductions in foreign aid.
Why It Matters
This development is significant because it demonstrates that an HIV-free generation is within reach, potentially transforming global health outcomes for children. Achieving zero new infections would mark a major milestone in ending AIDS as a public health threat.
However, setbacks due to aid reductions threaten to undo decades of progress, risking an increase in new infections and child deaths, which underscores the importance of sustained investment and access to prevention tools.

Background
During the 1990s, Uganda and other African nations faced devastating HIV epidemics, with high rates of mother-to-child transmission. Over the past three decades, international and local efforts—such as routine HIV testing for pregnant women and widespread availability of antiretroviral therapy—have drastically reduced transmission rates. Countries like Botswana now report so few new infections that they conduct federal audits for each case.
Recent years have seen progress challenged by political shifts and funding cuts, notably from US foreign aid, which could lead to a resurgence in childhood HIV infections if not addressed.
“We are actually confronting what it will take to finish this job. That is profound. That is progress.”
— Doris Macharia, President of the Elizabeth Glaser Pediatric AIDS Foundation
“It takes me back to those days when there was no access to medication, where there was no access to research. There was only a disease everyone fears.”
— Ismail Harerimana, community health worker in Uganda

What Remains Unclear
It remains unclear how recent reductions in foreign aid and health system disruptions will impact future progress, especially in countries with high HIV burdens. The extent of the possible increase in childhood infections and deaths due to these setbacks is still being assessed.

What’s Next
Next steps include restoring and increasing funding for HIV prevention and treatment programs, expanding access to testing and antiretroviral therapies, and implementing innovations like new prevention drugs such as Lenacapavir. Monitoring and addressing the impact of aid cuts will be critical in maintaining progress toward an HIV-free generation.

Key Questions
How close are we to eliminating mother-to-child HIV transmission?
Many countries, including Botswana, have made near-elimination progress, but globally, about 120,000 children are still infected each year. Continued efforts are needed to reach zero new infections.
What are the main barriers to preventing childhood HIV now?
Barriers include lack of access to testing and treatment for pregnant women, health system disruptions, and funding shortages, especially in high-burden regions.
Can new prevention drugs help end childhood HIV?
Yes, drugs like Lenacapavir show promise in preventing HIV transmission during pregnancy, but widespread access and rollout are still underway and depend on sustained funding.
What is the impact of funding cuts on HIV prevention?
Funding reductions threaten to reverse recent gains, potentially leading to increased infections and child deaths, especially in regions heavily reliant on international aid.
