The main strategies to reach this goal included improved routine immunization, adequate response to outbreaks and effective surveillance (2). Acute Flaccid Paralysis (AFP) surveillance has considered as a comprehensive program for polio eradication, by identification of areas of poliovirus transmission as well as cases of importation. Polio-free certification should be confirmed through surveillance (3). AFP surveillance has some indicators, where used to determine sufficient sensitivity of surveillance to detect poliovirus transmission in communities (4).
Table.1 shows two cores of AFP surveillance performance indicators including non-polio AFP and stool adequacy rates for Iran in 2016 (5). In the year of 2016 recorded the 776 AFP cases (Non polio AFP rate: 4.2 per 100,000
