Abstract
The state of West Bengal, India is endemic for bancroftian filariasis. But no information is available on filarial epidemiology among the tribal population of this state. Filariasis survey was conducted during night covering 1, 386 tribal people of Banpura district, West Bengal. Indoor-resting mosquitoes were collected from human habitations of the tribal areas and dissected. Microfilaria rate, mean microfilarial density, disease rate and endemicity rate were 3.3%, 6.3%, 5.6% and 8.6% respectively. Per man-hour density, infection and infectivity rates of the vector Culex quinquefasciatus were found to be 9.0%, 2.7% and 0% respectively.
