The Center for Global Health Policy’s “Science Speaks” blog “opens a week of tuberculosis coverage with a second post from a February visit to Haiti (the first, posted Feb. 26, is here), looking at efforts by physician John May and the non-profit Health through Walls to confront the disease in prisons there.” The blog highlights “a WHO bulletin that pointed to the impact of prison incarceration on the spread of the disease, noting that prisoners’ risk of being infected with tuberculosis is 26 times higher than that of the general population, and that prisoners’ risk of developing active tuberculosis disease is 23 times higher” (Barton, 3/18).
