A Study of Various Factors Determining the Quality of Acute Flaccid Paralysis Surveillance of Bee

摘要

Background: Surveillance of Acute FlaccidParalysis (AFP) is an important component ofpolio eradication campaign. In Beed district,this is being done since 1998 with the co-operation of national polio surveillance projectof the World Health Organization (WHO).Aims and Objectives: To review variousfactors, which determine the quality ofsurveillance. They include timeliness ofreporting units, taluka wise distribution, monthwise distribution, monitoring of non-polioacute flaccid paralysis rate, percentage ofnotification within 10 days, percentage of stoolsamples sent for virological study within 14days of onset of paralysis & reasons for delayin stool collection. Detection of non-polioenterovirus in stool cultures is an indicator ofquality of the reverse cold chain. Materials &Method: Surveillance network consists of 2very high priority, 4 high priority, 13 lowpriority reporting units & 25 informer units.Reporting units are expected to submit weeklyreports. A total of 315 cases of AFP wereinvestigated during last 10 years. Virologicalstudies are conducted at Haffkine.s Institute,Mumbai. Results & Conclusion: Timeliness ofreporting units varied from 77 to 99%. Zeroreporting blocks went down from 2-3 to 1.More cases of AFP were seen in months of July,august & September. Non polio AFP rate rangedfrom 1.38 to 7.35%. Percentage ofnotification within 10 days of onset wasbetween 72 to 94 %. Percentage of stoolsamples collected within 14 days of onset ofparalysis varied from 73 to 86%. A closevigilance on all these factors, at all levels ofadministration is essential to ensure that nocase of polio is missed out.
