One of the great innovations in global health over the past several years has been the use of so- called “health extension workers.” The idea is pretty simple: much of the developing world, particularly rural areas, is very hard to reach with health interventions. Health extension workers are typically women with some basic level of medical training who service hard-to-reach villages.
Ethiopia is one of the countries that pioneered this strategy, and it is yielding positive health outcomes. Here’s a great video from UNICEF about the program.
