8th International AIDS Society Conference on HIV Science, Paris, July 23-26

The focus of this conference was on biomedical prevention, particularly progress on implementation science for pre-exposure prophylaxis (PrEP).


Eastern and southern Africa (ESA) has seen a marked decline in HIV incidence in the past five years, attributed to scaled-up comprehensive national responses, including combination prevention and treatment. Swaziland is the leader here – with a 44% decline in new infections among adults 18-49 years when comparing two population-based studies (2011 and 2016).

Great progress has also been made towards achieving the 90-90-90 treatment targets. However, adolescents are performing poorly in all of the three 90s – lower testing, lower uptake of treatment, lower adherence and lower viral suppression. This was a common feature in all prevention, clinical and implementation science studies across the conference.
