Comparative Assessment of an Og4C3 ELISA and an ICT Filariasis Test: A Study of .Myanmar Migrants in Thailand

Lymphatic filariasis, mainly caused by the parasitic filarial worms Wuchereria bancrofti and Brugia malayi, is still a major public health problem in the tropics. Over 90% of the disease burden is due to W. bancrofti.1 The disease affects over 120million people2and persists as the second leading cause of clinical debility and disability worldwide.3The World Health Assembly has set the goal to eliminate lymphaticfilariasisas a public health problem.2To achieve this goal, the elimination program requires the collaboration of the public health systems in the affected countries. Furthermore, assessment and monitoring of the control programs' by efficient surveillanceprocedures are needed to determine where control efforts should be initiated, how effective they are, and when they may be discontinued.3
