Elimination of lymphatic filariasis in India--a successful endeavour.
World Health Assembly resolution in 1997 for elimination of lymphatic filariasis (ELF) by 2020 made all the filaria endemic countries in the world to put efforts for its elimination by progressively reducing and ultimately interrupting the transmission of lymphatic filariasis. National Health Policy, 2002 has set the goal for elimination of lymphatic filariasis (ELF) in India by the year 2015. In pursuit to achieve this goal, the strategy of mass drug administration (MDA) with annual single dose of diethylcarbamazine citrate (DEC) tablets was introduced in 2004 in all the filaria endemic states of the country and 202 districts were covered. Intensive information education and communication (IEC) and awareness campaign were organised and more districts were included for MDA in subsequent years after 2004.Presently 250 districts are covered under MDA. The coverage of population during MDA against eligible population in the country has been reported 73.19% in 2004, 71.54% in 2005, 60.92% in 2006 and 81.41% in 2007. The microfilaria (mf) rate estimated in sentinel and random sites of each filaria endemic district revealed that in 2007, 177 districts are with less than 1% mf rate and 73 districts are with more than 1%.
