Abstract

This article examines the evaluation of a bancroftian filariasis control programme undertaken in Pondicherry from 1981-5. Integrated vector management was applied in one half of the town, and routine operations under the national programme (larviciding and chemotherapy) continued in the comparison area. The programme was evaluated by monitoring relative change in the epidemiological statistics of both populations. The results indicate that there was significant reduction in prevalence of microfilaraemia in juveniles in the controlled area. An apparent reduction in intensity of microfilaraemia was also observed but this was a consequence of the reduction in prevalence, since the density of microfilariae remained unchanged. The results suggest that primary constraints on the epidemiological evaluation of the vector control of filarasis are the longevity and the population characteristics of the parasite.

摘要

本文考察了1981年至1985年在本地治里开展的班氏丝虫病控制项目的评估情况。在该城镇的一半区域实施了综合病媒管理,而对照区域继续按照国家项目进行常规作业(杀幼虫和化疗)。通过监测这两个人口群体流行病学统计数据的相对变化对该项目进行了评估。结果表明,在控制区域内,青少年微丝蚴血症的患病率显著降低。还观察到微丝蚴血症强度明显降低,但这是患病率降低的结果,因为微丝蚴的密度保持不变。结果表明,丝虫病病媒控制流行病学评估的主要制约因素是寄生虫的寿命和种群特征。
