Retrofitted from an 8–by–20 freight shipping container, Rx Box is a prototype mobile health clinic that promises to treat people in the poorest villages of the world. The Council on Foreign Relations and the Rensselaer Polytechnic Institute, which together developed Rx Box, unveiled the clinic in New York City on 14 June. The solar-powered Doc-in-a-box is designed to be staffed by one medic and offer 1,800 people each year primary care and screening for HIV/AIDS, hepatitis, tuberculosis and malaria. The prototype cost $4,000 to build, but the council estimates that mass production could cut that price by half.
