河北省1991-2001年脊髓灰质炎病原学监测

Surveillance on Pathology of Poliomyelitis in Hebei Province 1991 - 2001

河北省自1991年建立急性迟缓性麻痹(AFP)病例监测系统以来,脊髓灰质炎(脊灰)实验室的监测工作质量逐年提高,1995年以来已连续数年达到世界卫生组织(WHO)及卫生部规定的合格实验室的各项要求.为了进一步加强AFP病例的病原学监测,并为最终实现消灭脊灰的目标提供科学依据,现将河北省1991-2001年AFP病例病原学监测结果报告如下.

Objective To study the surveillance result of Poliomyelitis pathology in Heibei province 1991 -2001 and provide scientific basis for realizing the goal of evanishing Poliomyelitis. Methods The epidemiological investigation to the AFP cases reported by the Hebei province AFP surveillance system was conducted according to WHO' s normal method and all the Poliovirus strains were sent to the national lab and detected by the PCR - RFLP. Results Each surveillance target reached the WHO's requirement gradually and all the poliovirus isolated since 1992 were identified as vaccine poliovirus strains by the national lab of poliovirus. The season of Autumn - Summer was the peak period of non - poliovirus prevalence. Conclusions At the later stage of evanishing Poliomyelitis, the pathological surveillance of Poliomyelitis in the laboratory became more important. Therefore, we should strengthen the management scientifically and improve the surveillance quality in a lab. It is still an emphasis work for a laboratory to do it well.
