Dure Technologies

Dure Technologies is an innovative software solution and service provider for Public Health and Social Development sectors, with extensive experience in engaging with multilateral partners and organizations, working with global, national and sub-national programs and data. The Global ART Policy Watch portal has been developed leveraging Dure Technologies’ data visualization platform – iViZard – and it has been designed and implemented by a multinational team based in Switzerland and India.

From 2010 to the present, using the Internet we identified 109 national care continua that represented 94% of the 2015 global estimate of people living with HIV. We update the search on a quarterly basis and also incorporate newly published continuum as they become available in the public domain (please send and/or see the website submission tab if you have a new public domain continuum to bring to our attention).

We reviewed the methodology for collecting data on or estimating the following four key steps in the treatment cascade: 1. Estimated number of people living with HIV, 2. Estimated number of people living with HIV diagnosed as HIV-positive, 3. Estimated number of people living with HIV receiving ART, and 4. Estimated number of people living with HIV with suppressed or undetectable viral load.
