Abstract

The paper recently published by Coburn, Okano, and Blower (1) proposes the use of geospatial mapping to optimize resource allocation to eliminate HIV in Lesotho, a small landlocked country in Southern Africa with a population of about 2 million and an HIV prevalence of approximately 25% in urban centers and 21% in rural settlements. In their study, the authors describe a geostatistical framework for designing a novel treatment as prevention (TasP) for HIV elimination strategy (2). They make the argument that reaching the UNAIDS goals of 90-90-90 (diagnosed-treated-virologically suppressed) may be quite dif cult in some rural communities. Consequently, they propose to focus efforts in urban areas with a high density of infection.
