A 5-year Integrated Vector Management (IVM) project was implemented in Pondicherry, South India, for the control of Bancroftian filariasis. The efficacy of the IVM strategy was compared with routine control strategy under the national programme. The present paper describes the pre-control epidemiological features of filariasis as determined by a mass blood survey in 1981. Of 24946 persons examined 8.41% were microfilaraemic. Microfilaraemia prevalence was homogeneous throughout the study area. The prevalence and intensity of microfilaraemia were age dependent, and increased monotonically until about 20 years, following which there was a decline until about 40 years to become relatively stable in older age classes. The gender profiles of both prevalence and intensity of microfilaraemia showed no difference between the sexes until about 15 years of age, following which both were higher in males compared to females. The distribution of microfilarial counts was overdispersed, indicating aggregation of adult worms.
在印度南部本地治里开展了一项为期5年的综合病媒管理（IVM）项目，以控制班氏丝虫病。在国家项目下，将综合病媒管理策略的效果与常规控制策略进行了比较。本文描述了1981年通过大规模血液调查确定的丝虫病控制前的流行病学特征。在接受检查的24946人中，8.41% 为微丝蚴血症患者。微丝蚴血症患病率在整个研究区域内是均匀的。微丝蚴血症的患病率和强度与年龄有关，在20岁左右之前单调增加，之后下降至40岁左右，在老年人群中相对稳定。微丝蚴血症的患病率和强度的性别分布在15岁左右之前没有性别差异，之后男性的患病率和强度均高于女性。微丝蚴计数的分布呈过度分散，表明成虫聚集。
