World AIDS Day takes place annually on 1 December as an opportunity for people worldwide to unite in the fight against HIV and to show support for people living with HIV/AIDS.

To mark World AIDS Day 2017, we have published a series of blog posts to highlight the important and varied research that takes places at Imperial. Three experts from Faculty of Medicine share their interest in HIV/AIDS which spans from the elusive vaccine to the economics of the epidemic.


The role of an economist in the HIV epidemic

As an economist, my research on HIV takes a higher-level population view. We advise policy makers in governments and international organisations on the cost-effectiveness of preventive and treatment interventions in the countries most ravaged by HIV. By estimating the benefits and costs of interventions, we can identify the ones that promise greatest improvements in population health.

The largest community-randomised trial of the universal HIV test and treat strategy

For example, we are currently conducting an economic evaluation of HPTN071/PopART; the largest study on the impact of a package of testing and prevention interventions on new infections in Zambia and South Africa. We measure the benefits of treatment to HIV-infected individuals who are found and diagnosed earlier because of PopART, and we expect that the interventions will also prevent new infections. It’s tricky to estimate exactly how many individuals will be spared from getting infected in future, but we work with epidemiologists who use complex modelling to project the number of prevented infections into the future.
