title: Status of lymphatic filariasis in Lucknow District, Uttar Pradesh.
abstract: Lucknow district was endemic for lymphatic filariasis (LF). During March 2008, LF survey was carried out in 14 randomly selected villages (six Primary Health Centres) and 4 Mohallas of Lucknow city. Out of 3,654 night blood smears (NBS) collected and examined, 209 were found positive for Wuchereria bancrofti (micrifilaria rate: 5.7%). Microfilaria (mf) carriers were detected from all surveyed villages and Mohallas. The age of these positive persons ranged from 6-70 years. In all areas, prevalence of microfilaraemia generally increased with age up to 21-30 years. Males (6.7%) were more affected than females (3.9%). All mf carriers were residents of Lucknow district. Overall disease rate was 4.7%. In all, 175 individuals had disease manifestations of LF. Out of 108 males, 81 had hydrocele(75%). Disease rate was similar in males (4.7%) and females (4.8%). The mean mf density was 9.5 per 20 cmm blood, but no significant difference between males (9.4) and females (9.9). Vector density ranged from 150 to 810 per ten-man-hours. Infectivity and infection rates were 0.14%. The present survey indicates that filariasis is one of the major public health problems in surveyed areas.
