为了解北京市 2 0 0 3年维持无脊髓灰质炎 (脊灰 )进展、急性弛缓性麻痹 (AFP)病例流行病学特征和监测系统运转情况 ,对北京市 2 0 0 3年AFP病例进行分析 ,对AFP病例监测系统进行评价。结果显示 :北京市 2 0 0 3年共报告本地AFP病例 2 0例 ,其中 <1岁 4例 (2 0 %) ,1～ 4岁 7例 (35 %) ,>4岁 9例 (45 %)。口服脊灰疫苗 (OPV) 1次的 2例 (1 0 %) ,≥ 3次的 1 6例 (80 %) ,不详的 2例 (1 0 %)。共采集了 4 0份粪便标本 ,未分离到脊灰病毒。 2例AFP病例的 4份粪便标本 (1 0 %)分离到非脊灰肠道病毒 (NPEV)。 2 0例AFP病例最后分类为 :脊灰确诊病例 0例 ,临床符合脊灰病例 1例 (5 %) ,脊灰排除病例 1 9例 (95 %)。AFP病例监测系统评价指标均达到了卫生部的要求。表明北京市 1 985～ 2 0 0 3年已连续 1 9年无脊灰野病毒病例报告。AFP病例监测系统已具有监测出脊灰野病毒的能力 ,今后应进一步消除监测中的漏报和免疫空白点 ,保持北京市无脊灰状态。
To understand the epidemiological characteristics of poliovirus (poliovirus) -free polio (polio) in Beijing in 2003, the epidemiological characteristics of acute flaccid paralysis (AFP) and the operation of monitoring system, the AFP cases in Beijing in 2003 were analyzed , AFP case monitoring system evaluation. The results showed that 20 cases of local AFP cases were reported in Beijing in 2003, including 4 cases (20%) under 1 year old, 7 cases (35%) at 1 ~ 4 years old and 9 cases (45% ). Two cases (10%) of oral poliomyelitis vaccine (OPV) once, 16 cases (80%) of ≥3 times and 2 cases (10%) of unknown. A total of 40 fecal specimens were collected, and no poliovirus was isolated. Non-polio enterovirus (NPEV) was isolated from 4 stool specimens (10%) of 2 AFP cases. The final classification of 20 cases of AFP was: 0 cases of confirmed poliovirus, 1 case (5%) of poliovirus and 19 cases (95%) of poliovirus cases. AFP case monitoring system evaluation indicators have reached the requirements of the Ministry of Health. It shows that there was no case report of poliovirus in Beijing from 1985 to 2003. AFP case monitoring system has been monitoring of the ability of poliovirus, the future should further eliminate the omission in monitoring and immunization gaps to maintain the state of Beijing’s polio-free.
