Status of lymphatic filariasis in some select slum clusters of Delhi.
Filaria surveys conducted in some select slum clusters namely Hari Nagar, Yamuna pusht near Vijaya Ghat along the Ring Road and Timarpur in Delhi during 1989, 1991 and 1992 respectively, covering a population of approximately 5000 slum dwellers revealed the presence of bancroftian microfilaria (mf) carriers and disease cases. The mf and disease rates (per cent) in these three slum areas were in the order of 6.3, 2.2, 3.7 and 1.4, 0.5 and 0.1 respectively. The mf density varied from 3.1 to 12.3 per 20 cumm. blood. High ten man hour densities of Culex quinquefasciatus (581) in Yamuna pusht followed by (355) in Timarpur were recorded during entomological investigations. Hari Nagar accounted for least ten man hour density of Cx. quinquefasciatus (160), because collection was made during winter months (November-December). The dissection of Cx. quinquefasciatus did not reveal any human filarial infection except in Yamuna pusht where out of 139 only one Cx. quinquefasciatus was found infective.
