Blood and clinical surveys were made on the total populations of two villages in Thakurgaon thana, Dinajpur District, East Pakistan, an endemic area for bancroftian filariasis. Infection rates in the two villages were 15.6% and 16.4%, with male disease rates of 21.7% and 20.6% respectively. Disease manifestations were almost exclusively hydrocele, with only a rare case of scrotal or limb elephantiasis. Only one female was found to have elephantiasis, but over one-third of the adult males had hydroceles. Possible reasons for this preponderance of hydroceles in a highly endemic area are discussed. Historical data and the finding of long-standing hydroceles in older males native to the area indicates that filariasis pre-dated the large influx of immigrants from neighboring endemic areas of India during the past 20 years.
