Why the study?
Effective acute flaccid paralysis surveillance is crucial in countries approaching the final phase of polio eradication, motivating this evaluation of its epidemiological pattern as a surveillance tool for polio in Egypt.
AFP surveillance in Dakahlia, Egypt met WHO performance indicators, confirming polio-free status over a 9-year period.

AFP surveillance data from Egypt informs polio monitoring; leaves open whether rates meet eradication benchmarks.
BACKGROUND: Effective acute flaccid paralysis (AFP) surveillance is crucial in countries approaching the final phase of polio eradication. Thus this study was conducted to highlight the epidemiological pattern of AFP as a surveillance tool for polio in Egypt. METHODS: A record-based descriptive study was conducted to include all AFP cases (599) reported in the last 9 years starting from January 2009 to December 2017 in Dakahlia, North East of Delta, Egypt. RESULTS: The overall non-polio AFP rate in less than 15 years old children was 2.99/100,000 during the study period. The majority of cases (98%) were notified within 7 days from onset of the disease, and investigated within 48 h of reporting. The commonest diagnoses were encephalitis (21.3%), myositis (20.2%), neuropathies (19.2%) and Guillain-Barre syndrome (17.8%) with no recorded cases diagnosed as poliomyelitis. The mean annual vaccination coverage rate was 96.1 ± 1.6. CONCLUSIONS: AFP surveillance system in Dakahlia, Egypt was effective in meeting the WHO surveillance performance indicators ensuring polio-free status and absence of wild polio virus transmission over the last 9 years in this locality. High routine immunization coverage, maintenance and improvement of current levels of surveillance performance are required for optimum surveillance.
