Mass drug administration to eliminate lymphatic filariasis in India.

Mass drug administration (MDA) to eliminate lymphatic filariasis is already in place in 32 out of 83 endemic countries. Expansion of the MDA programme to other countries and within large countries such as India is necessary to achieve the goal of lymphatic filariasis elimination. However, expansion and sustenance of the global campaign to eliminate lymphatic filariasis requires commitment and allocation of funds by governments and donor agencies. This could be achieved, at least to some extent, by highlighting the benefits of the programme in relation to costs. On the basis of various studies in south India, this article assesses the costs, effectiveness and economic and social benefits of the MDA programmes aimed at eliminating lymphatic filariasis.
