A total of 4492 persons from 5 panchayats and 1 town were investigated from the Brugia malayi most endemic taluk of Cherthala, Alappuzha district of Kerala state. The urban area in Cherthala taluk only revealed mf carriers; mf rate was 0.13%. Rural areas in Cherthala taluk were free from infection. Microfilaria rate had declined by 99.5% and disease rate by 90.7% in Cherthala compared to 1934 prevalence. Shedding of sheath by B. malayi microfilariae was recorded for the first time in India. The youngest person with microfilaria and disease manifestation was 4 1/2 and 9 years respectively. All the 3 major vectors, Mansonia annulifera, Ma.uniformis and Culex quinquefasciatus were prevalent throughout. Complete disappearance of brugian filariasis from this taluk is a distinct possibility. The reasons for the drastic decline are discussed.
在喀拉拉邦阿拉普扎县切尔塔拉地区布鲁氏丝虫病最流行的塔卢克，对来自5个村和1个镇的4492人进行了调查。切尔塔拉塔卢克的市区仅发现微丝蚴携带者，微丝蚴率为0.13%。切尔塔拉塔卢克的农村地区未发现感染病例。与1934年的患病率相比，切尔塔拉的微丝蚴率下降了99.5%，疾病率下降了90.7%。在印度首次记录到马来布鲁氏丝虫微丝蚴脱鞘现象。感染微丝蚴和出现疾病症状的最年轻患者分别为4岁半和9岁。3种主要病媒，即环纹曼蚊、同型曼蚊和致倦库蚊，在该地区均普遍存在。该塔卢克完全消除布鲁氏丝虫病是完全有可能的。文中讨论了大幅下降的原因。
