Improved assessment of mass drug administration and health district management performance to eliminate lymphatic filariasis.
Lymphatic filariasis (LF) elimination as a public health problem requires the interruption of transmission by administration of preventive mass drug administration (MDA) to the eligible population living in endemic districts. Suboptimal MDA coverage leads to persistent parasite transmission with con...
