Abstract
Background: Acute Flaccid Paralysis (AFP) was adopted by World Health Organization (WHO) in
1988 as a key pillar used in monitoring progress towards the global polio eradication initiative.
High quality AFP surveillance is essential to support this global initiative. We applied recently de-
veloped case verification methods for the quantitative evaluation of AFP cases reported to the
surveillance systems to evaluate the quality of AFP reports in Akwa Ibom State, Nigeria. Objectives:
The aim of this study is to identify the demographic, clinical and epidemiological attributes and
quality of acute flaccid paralysis surveillance. Methods: All AFP cases reported in children 0 - 14
years during January 2006 to December 2012 were investigated and verified by WHO surveillance
officers, using standard questionnaire. Two stool samples 24 - 48 hours apart from a total of 1184
AFP cases were collected within 14 days of onset of paralysis with the prior oral/verbal informed
consent and transported to the national polio laboratory under reverse cold chain. Result: In all,
885/1184 representing 75% of the AFP cases reported were verified by WHO officers in the pe-
riod under review. Overall, 534/885 (60.3%) of AFP cases had more than >3 doses of Oral Polio
Vaccine (OPV), while 196/885 (22.2%) received 3 dose of OPV and 128/885 (14.5%) received
between 1 - 2 doses of OPV. It was interesting that 27/885 (3%) never received OPV before. Over-
all, 743/885 (84.0%) were reported within ≤14 days of paralysis onset, while 142/885 (16%)
