Post-Mass Drug Administration Transmission Assessment Survey for Elimination of Lymphatic Filariasis in La Ciénaga, Dominican Republic.
The Dominican Republic is one of four remaining countries in the Americas with lymphatic filariasis (LF). Annual mass drug administration (MDA) with albendazole and diethylcarbamazine was conducted in La Ciénaga, an impoverished urban barrio in Santo Domingo, from 2004 to 2006. Eight years after the last MDA, a transmission assessment survey (TAS) was conducted in November-December 2014 to determine if LF transmission remains absent. Of 815 first and second grade primary school students (mean age: 6.51 years; range 5-9) tested by immunochromatographic test (ICT), zero (0.0%) were positive. This is below the TAS critical cutoff of nine, indicating that the area "passed" TAS and that transmission remains interrupted in La Ciénaga. Importantly, this also provides evidence that three rounds of effective (> 65% coverage) MDA, likely aided by environmental improvements and periodic school-based albendazole monotherapy MDA, achieved interruption of LF transmission from a relatively low-transmission setting.
