The Center for Global Health Policy’s “Science Speaks” blog highlights a recently published PLOS One article on HIV treatment as prevention in British Columbia, Canada. “…[T]he findings reflect similar findings showing population-wide impacts of HIV treatment as prevention, the authors say, noting ‘the magnitude of the impact of the expansion of HAART coverage on HIV transmission derived from our models is entirely consistent with the effect noted from the experience in Kwazulu-Natal.’ That experience, published in Science magazine last year, showed the more antiretroviral treatment coverage increased in KwaZulu Natal the more steeply rates of acquisition of HIV declined” (Barton, 2/14).
