Tackling the “last mile”—the final, critical step of delivering products or services to consumers—is a conundrum for businesses, and in health care, last-mile problems hit poor regions especially hard. Panjabi’s nonprofit, Last Mile Health, is striving to change that by training locals in developing countries in lifesaving ­measures, such as protecting themselves against pandemics and safely burying victims killed by infectious diseases. Last Mile has already proved its mettle; its work in Liberia helped stanch the spread of Ebola during the 2014 outbreak.
