Overview

In 1997, the 50th World Health Assembly resolved to eliminate lymphatic filariasis as a public health problem. In response, the World Health Organization (WHO) established the Global Programme to Eliminate Lymphatic Filariasis to assist Member States in achieving this goal by 2020. The global programme has two components (i) reducing prevalence of infection to levels at which it is assumed that transmission can no longer be sustained; and (ii) managing morbidity and preventing disability

WHO recommends that all Member States where lymphatic filariasis is endemic should implement transmission assessment surveys at the end of the MDA phase in order to move to the post-MDA surveillance phase. Repeated TAS surveys are encouraged as a means of post-MDA surveillance and eventually to provide evidence that transmission has successfully been interrupted. Implementation of TAS will also help endemic countries to meet the targets set by the Strategic Plan of the Global Programme to Eliminate Lymphatic Filariasis.

The success of the Global Programme to Eliminate Lymphatic Filariasis will depend on the collective efforts of national governments, WHO, nongovernmental organizations, donors, pharmaceutical and diagnostics companies, endemic communities and other partners to document that transmission is effectively interrupted. All Member States are therefore encouraged to support national, regional and global efforts to reach the 2020 target for elimination of lymphatic filariasis.
