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.
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.
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.
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.
在接近消灭脊灰最后阶段的国家，有效的急性弛缓性麻痹（AFP）监测至关重要。因此，本研究旨在突出 AFP 作为埃及脊灰监测工具的流行病学模式。
本研究采用基于记录的描述性研究，纳入了 2009 年 1 月至 2017 年 12 月 9 年间在埃及东北部达卡利亚报告的所有 AFP 病例（599 例）。
在研究期间，15 岁以下儿童的总非脊灰 AFP 发病率为 2.99/100,000。大多数病例（98%）在发病后 7 天内报告，在报告后 48 小时内进行调查。最常见的诊断为脑炎（21.3%）、肌炎（20.2%）、神经病（19.2%）和格林-巴利综合征（17.8%），无记录的脊灰病例。平均年疫苗接种覆盖率为 96.1±1.6。
埃及达卡利亚的 AFP 监测系统在过去 9 年中有效地满足了世卫组织监测绩效指标，确保了该地区脊灰无疫区状态和野生脊灰病毒传播的不存在。需要保持和提高当前的监测绩效水平，以实现最佳监测。
