Reasons for missed children during SIA in the first half of 2012 based on independent monitoring data from the three regions that have yet to interrupt indigenous poliovirus transmission: southern Afghanistan, Pakistan and northern Nigeria. The proportion of all children 0–4-years old who were identified as missed is shown by the figures in brackets. In southern Afghanistan the ‘other’ category specifically refers to cases where the child was a neonate, asleep or sick. Southern Afghanistan includes Kandahar, Helmand, Urozgan, Zabul and Nimroz provinces. Northern Nigeria includes Bauchi, Borno, FCT Abuja, Gombe, Jigawa, Kaduna, Kano, Katsina, Kebbi, Plateau, Sokoto, Yobe and Zamfara states. Data courtesy UNICEF PolioInfo (www.polioinfo.org).
