Effectiveness Of HIV Pre-Exposure Prophylaxis In Men Who Have Sex With Men And Transwomen In Lima, Peru

In this week’s PLOS Medicine, from Imperial College London and an of authors developed a mathematical model representing the epidemic among (MSM) and transwomen in Lima, Peru as a test-case for the effectiveness of HIV pre-exposure (PrEP).

The model was used to investigate the population-level impact, cost, and cost-effectiveness of PrEP under a range of different scenarios.

The authors found that strategic PrEP intervention could be a cost-effective addition to existing for MSM populations. However, despite being cost-effective, a substantial expenditure would be required to generate significant reductions in incidence of HIV.
