[Editorial] Cancer consequences of the HIV funding crisis

Reductions in development assistance funding by previous major donors—the USA, the UK, France, and Germany—have led to substantial challenges to global HIV control in 2025. Against this stark backdrop, World AIDS Day 2025 was commemorated globally on Dec 1, 2025. UNAIDS released a report ahead of the day detailing the impact of the unprecedented changing international aid landscape on global HIV control programmes worldwide, particularly in low-income and middle-income countries. Failure to meet the 2030 global HIV targets could result in an additional 3·3 million new HIV infections between 2025 and 2030, according to the report.
