TL;DR: Comprehensive surveillance is feasible for some national filariasis elimination programs and use of antibody and MX testing as tools to complement TAS for post-MDA surveillance is recommended.

TL;DR: Results suggest that W. bancrofti transmission was near the break point in some of the areas studied in 2011–13, and test and treat or other programs targeting adult males plus bed net promotion may be more effective than MDA for clearing remaining hotspots of transmission in Sri Lanka.
Programmatic Use of Molecular Xenomonitoring at the Level of Evaluation Units to Assess Persistence of Lymphatic Filariasis in Sri Lanka.

TL;DR: This study has shown that MX can be used by national programs to assess and map the persistence of W. bancrofti at the level of large EUs in areas with Culex transmission and suggests there is widespread persistence in the coastal Galle EU 8 years after the last round of MDA.
Comprehensive Assessment of a Hotspot with Persistent Bancroftian Filariasis in Coastal Sri Lanka

TL;DR: Interventions other than routine MDA will be required to remove LF hotspots in Balapitiya and in other areas in coastal Sri Lanka.
Systematic sampling of adults as a sensitive means of detecting persistence of lymphatic filariasis following mass drug administration in Sri Lanka
Ramakrishna U. Rao,Sandhya D. Samarasekera,Kumara C. Nagodavithana,Manjula W. Punchihewa,Udaya S. B. Ranasinghe,Gary J. Weil +5 more
TL;DR: Community based adult-TAS provided a reproducible measure of persistent W. bancrofti infection in a large evaluation unit in Sri Lanka that has low-level persistence of LF following multiple rounds of MDA.
