Prevention has been a key focus of the Rome conference. ‘Treatment as prevention’ has received much of the attention, as the evidence for this concept – and a range of associated benefits – is now clear.
People concerned with HIV from every angle, whether personally affected or professionally involved, are starting to explore the full implications – practical, financial, social and legal – for developing a global prevention tool based on HIV treatment.
In two consecutive sessions the focus was on how the prevention potential of treatment could be put into practice.
Rolling out treatment as prevention will involve considerable expenditure on both drugs and human resources.
Another major barrier will be getting people to come forward for testing – particularly stigmatised or criminalised populations such as injecting drug users, sex workers and, in some countries, men who have sex with men.
Matching prevention methods to individual circumstances was also mentioned as a priority.
