WINTER 2014 In partnership with the Vietnam National Tuberculosis Program and the University of California, San Francisco, Fletcher’s group deployed 15 CellScopes for a full year, to evaluate their uptake and ability to detect TB at health care facilities with little medical or IT infrastructure. The Hanoi Province pilots showed that community health care workers were able to operate the CellScope and that disease diagnosis met the standard quality available at major Vietnamese hospitals. This work motivated development of a second generation device that is being tested in Hanoi. Recently, another CellScope device was field-tested in Cameroon where the Gates Foundation and the U.S. National Institutes of Health had been struggling to find a way to restart mass drug administration programs to fight the roundworms that cause river blindness and lymphatic filariasis. The problem health workers faced was that patients were at risk of serious health complications, including death, if they were given river blindness medication while coinfected with the Loa loa worm. But to test for Loa loa, health workers needed to draw several millilite
