The nomadic communities in Nigeria have been identified as containing the highest number of “zero dose” children. The Nomads Project, as part of Nigeria's National-Stop Transmission of Polio (N-STOP) polio eradication program, posted Nigerian Field Epidemiology Training Program (NFETP) residents to train indigenous data collectors and guides, for a supervised enumeration exercise. Three hours from the nearest town this boy was found wandering alone, while his parents and older siblings were out grazing cattle. His response to being alone was, "I matter -- that's why you were sent to find me at home in the forest.” The image was captured on August 20, 2012, in the Kanoma ward, of the Maru Local Government Area (LGA), in the Zamfara state of Nigeria.
The N-STOP program is a refined and specialized offspring of two larger programs that train disease detectives: the (international) STOP program, and the Nigeria Field Epidemiology and Laboratory Training Program. N-STOP is a key element in Nigeria’s effort to rid the country of this crippling disease.
