health planners and therefore affordability of filariasis control is particularly important.

BIBLIOGRAPHY

186 Also it has been reported that use of DEC medicated salt for a period of 9-12 months has been shown to be simple, inexpensive and effective in drastically reducing or eliminating lymphatic filariasis (WHO, 1994)'. Filariasis control is generally given low priority by health planners and therefore affordability of filariasis control is particularly important. Since DEC medicated salt relies on existing community purchasing practice, it requires the least resource input. Though some increase in purchasing cost to the consumer is estimated (US $ 0.8/year/adult), considering the goal of elimination of filariasis, this additional cost may be met either by government or by some voluntary organization. In view of the above findings and considering the life span of the adult microfilaria worm (5-10 years), a DEC medicated salt programme undertaken at a national level for at least 10 years throughout the filaria endemic belt may be able to eliminate the parasite. Future research should concentrate on the extent of social stigma, duration of the disease manifestation and subsequent economic loss to the individual and family, role of community participation and methods for enrolling in filariasis control. # It is generally well tolerated, sdely used in pregnancy and can be incorporated into iodized salt
