Objective To analyze the epidemiological characteristics of Acute Flaccid Paralysis (AFP) from 2007 to 2011 in Yibin, evaluate the operation of the monitoring system, and improve the sensitivity and specificity of detection and to consolidate the results of polio-free. Methods Epidemiological methods were used to analyze the epidemiological characteristics of AFP cases in Yibin. The AFP monitoring system was evaluated according to the monitoring indicators stipulated by the World Health Organization (WHO) and the Ministry of Health.
