目的了解娄底市急性弛缓性麻痹(AFP)病例流行病学特征,评价AFP病例监测系统运转情况。方法用EPI info软件对全市AFP病例的个案调查表及监测报表的资料进行统计分析。结果1994年～2005年共报告AFP病例222例,报告发病率为1.98/10万,病例呈高度散发,无明显的季节高峰,4岁以下病例占65.32%,未完成全程免疫者占20.72%。AFP合格粪便标本采集率为92.09%。实验室肠道病毒分离阳性率为14.42%,其中分离到脊髓灰质炎疫苗相关病毒18株,未分离出脊髓灰质炎(脊灰)野病毒。结论1993年建立AFP监测系统以来,监测质量逐年提高,连续11年未发现脊灰野病毒病例。为维持无脊灰状态,必须加强AFP监则系统的管理,提高其敏感性、及时性、完整性。
Objective To understand the epidemiological characteristics of acute flaccid paralysis (AFP) in Loudi and evaluate the operation of AFP surveillance system. Methods The EPI info software was used to make statistical analysis on the case investigation form and the monitoring report data of AFP cases in the city. Results A total of 222 cases of AFP were reported from 1994 to 2005, with a reported incidence of 1.98 / 100 000. The cases were highly distributed with no obvious seasonal peak, accounting for 65.32% of cases under 4 years of age and 20.72% of those not completing full course immunization. AFP qualified stool specimens collected rate of 92.09%. The positive rate of laboratory enterovirus isolation was 14.42%. Among them, 18 poliovirus-associated viruses were isolated and no poliovirus (poliovirus) was isolated. Conclusion Since the establishment of AFP monitoring system in 1993, the quality of monitoring has been increasing year by year. No cases of poliovirus have been found for 11 consecutive years. In order to maintain a polio-free status, it is necessary to strengthen the management of the AFP Monitoring System to enhance its sensitivity, timeliness and completeness.
