The current program to eliminate lymphatic filariasis (LF) is based on the expectation that 4 to 6 rounds of annual mass drug administration (MDA) with population coverage at least 80% will result in unsustainable transmission leading to regional elimination. However, transmission has not been halted in some regions after putatively achieving these outcomes, possibly due to population movement/migration and spatial heterogeneities in infection and transmission. This study analyzes four years of weekly demographic surveillance records and annual infection surveys from a field trial of annual MDA in four communities of Papua New Guinea. Houses were geolocated in reference to transmission sites. Individual infection status and population MDA effectiveness was analyzed with regard to migration and clustering of infection. Results from this study may be useful to better design MDA distribution and monitoring strategies for LF elimination programs.
