Years of progress in tackling HIV, viral hepatitis and sexually transmitted infections (STIs) are at risk of stalling, leaving millions without access to life-saving prevention, testing and treatment, the World Health Organization (WHO) has warned, according to a press release. A new analysis released on 28 July 2026 found that while countries have made significant advances over the past decade, funding shortfalls, humanitarian crises and persistent inequalities are widening gaps in care. The report signals that hard-won global health gains could quickly unravel without sustained investment.
