Introduction: Beijing has been polio free since 2000.  However, public health faces precedent challenges in Beijing, an international hub with more than 24 million residents, where the majority of AFP cases are non-Beijing residents who seek medical treatment and frequently move and change their residing locations. In 2011, an integrated and centralized Acute Flaccid Paralysis (AFP) Surveillance System has been developed and implemented in Beijing to track, investigate, test, verify, manage, transfer, and follow up AFP

Method:

A detailed and comprehensive AFP surveillance plan has been modified over time and strongly enforced. The AFP system integrates all sources of information into a centralized platform that allow for exchanging, sharing, and updating information for reporting and receiving by local CDCs in addition to the National CDC.  The system consolidates data from active surveillance systems that are implemented at all hospitals in Beijing, clinical and epidemiological investigation reports, biological test and results, expert panel reviews and versification, and follow ups by either the Beijing CDC or CDC of residency after the cases are transferred back to their respective residency. The system also builds interfaces with the National Infectious Disease Reporting System.

Results: 

From 2012 to 2014, total of 588 AFP cases were reported. Of them, 82.7% of cases were migrants; age < 2 accounted for 36.6%, age 3-6 for 32.0%, age 9-10 and 10 -14 for 15.5%and 15.8% respectively.  85.2% of AFP cases had an investigation conducted with sample collection in 24 hours after initial report. All migrant cases were transferred to their corresponding local CDCs for follow up through the system in a timely fashion. No wild polio cases were identified. One case of Vaccine Highly-Variant Poliovirus (Beijing resident), and 8 of Vaccine Poliovirus were identified (7 migrant cases).

Conclusions: this robust system has met the needs and requirements of public health and demonstrates improved AFP surveillance in terms of effectiveness, completeness, and timelineness. In particular, this system integrates all components in a platform for electronic data exchange, sharing, case management, follow-up and update, and is a model for other public health surveillance systems.
