Objective To evaluate effectiveness of strategies for maintaining polio-free status in Hefei. Methods Epidemiological methods were used to analyze monitoring data of acute flaccid paralysis （AFP） cases and coverage rates of poliomyelitis vaccine. An emergency response was exercised to test the effectiveness of a plan for handling imported, wild poliovirus. Results The average reported AFP in- cidence among children under 15 years old was 2.35 per 100,000 population in Hefei during 2012-2015. All performance indicators met national requirements for an AFP monitoring system. The average reported coverage of polio vaccine was 99.83%. We developed a plan for handling imported, wild poliovirus, and we conducted an exercise of emergency response. Conclusions The AFP monitoring system in Hefei runs well, and the coverage rate of polio vaccine in children was maintained at a high level. The plan for handling imported wild poliovirus is feasible and effective for maintaining polio-free status in Hefei.
