Update on treatment as prevention of HIV illness, death, and transmission: sub-Saharan Africa HIV financing and progress towards the 95-95-95 target

Abstract

Purpose of review: After over 40 years, the HIV pandemic is amongst the deadliest in history - 100% fatal without treatment, HIV has infected over 84 million people, and has caused over 40 million deaths. Global HIV spending between 2000 and 2015 totaled over a half trillion dollars. Delays in harnessing scientific advances, including 'test and treat' and treatment as prevention of illness, death, and transmission (TasP) provide a cautionary tale applicable to other pandemics. Resource allocation has also been problematic with many highest burden countries spending less than 50% on care and treatment.

Recent findings: Between 2002 and 2021, over $94 billion was budgeted for HIV in 40 sub-Saharan African countries, with 19 countries over $1 billion. In 2021, 8.1 million (32%) People Living with HIV (PLHIV) are still not on treatment; viral suppression data, the most important programme success indicator, is unavailable for 50% of countries. Of 19 countries with at least one billion dollars budgeted, seven have below 80% ART coverage, leaving 3.5 million (29%) of PLHIV off treatment and vulnerable to illness, death, and transmitting the virus to partners and children.

Summary: With additional funding and improved efficiency, achieving the 95-95-95 target to diagnose 95% of all HIV-positive individuals, provide antiretroviral therapy (ART) for 95% of those diagnosed and achieve viral suppression for 95% of those treated by 2030 is feasible and the humane pathway towards ending the HIV pandemic.
