The aim of this study is to verify the level of transmission of @entity3754 three years after stopping mass drug treatment in the 7 endemic districts in Togo. The survey was conducted in 2012 in Togo's 7 endemic districts grouped into four evaluation units (EU) using theWHO-recommended @entity1579 ( @entity1579 ) protocol. @entity1 aged 6-7 years were screened for @entity10065 bancofti antigen using the immunochromatographic card (ICT) method. A cluster sampling method was used to select eligible @entity1 in schools as the net primary-school enrolment ratio is greater than or equal to 75% in each of the four EUs. The number of @entity1 and schools to be selected in each EU, the randomization list for the selection of these @entity1 and the critical cut-off number of positive cases not to exceed were automatically generated using the Survey Sample Builder (SSB) tool, (NTD Support Center, Atlanta, Ga, USA). For confirmation, positive cases were subsequently tested for microfilaremia using nocturnal thick blood smear and for filarial antigen using Og4C3 antigen ELISA (TropBio ELISA Kit  , Townsville, Queensland, Australia). An EU is considered to have passed the test successfully (it is assumed that transmission can no longer be sustained), when the number of positive cases is below the critical cut-off number set by the SSB, which is roughly equivalent to 2% prevalence. Of the 1 706 @entity1 surveyed in @entity2421 's EU, 1 549 in Binah-Doufelgou's EU, 1 550 in Kozah's EU and the 1 575 in Amou-Haho's EU, 8 (0.46%), 1 (0.08%), 0 (0.00%) and 4 (0.25%) ICT positive cases respectively were detected. The number of positive ICT tests was well below 18, the criticalcut number for each of the 4 EUs. All 13 ICT positive cases tested negative for nocturnal microfilaremia and Og4C3 ELISA. We conclude that all four EU passed the @entity1579 with success, and the transmission of @entity10065 is no longer likely to be sustained in the 7 endemic districts in Togo 3 years after stopping the @entity1865 . A new @entity1579 will be carried out in 2015, after which, if the results are still good, the country will submit a dossier to WHO for verification of the elimination of @entity3754 .
