Abstract: WHO and many other organisations are very interested in implementing treatment-as-prevention as a global policy to control the HIV pandemic. Widespread treatment of HIV-infected individuals with antiretroviral therapy will reduce HIV transmission, because it decreases viral load and hence infectiousness. To implement the rollout of treatment-as-prevention in an efficient manner, estimation of the number of HIV-infected individuals and where they live is needed. This assessment will be difficult to accomplish, particularly in areas of sub-Saharan Africa with severe HIV epidemics.
