Lymphatic filariasis

Lymphatic filariasis is one of the world's leading causes of permanent and long-term disability. The disease can cause serious impact on the health and the socioeconomic status of the people affected.

Elimination of lymphatic filariasis can be achieved through annual mass drug administration of diethylcarbamazine or ivermectin in combination with albendazole. To reach the goal of elimination, high coverage rates during the mass drug administrations need to be sustained for at least 4-6 years.

Lymphatic filariasis is currently endemic in 21 countries of the WHO Western Pacific Region.

Ninth Workshop for Pacific Lymphatic Filariasis Programme Managers
The Pacific Programme to Eliminate Lymphatic Filariasis (PacELF) began with 22 countries, of which 11 were endemic for lymphatic filariasis (LF). Three of these countries have now reduced their LF prevalence rates to below 1%, with the other eight continuing activities to eliminate the disease.

Sixth Mekong-Plus Workshop for Lymphatic Filariasis Programme Managers
The Mekong Plus region has a diverse range of countries with few highly endemic countries, few countries close to elimination and others which already have eliminated Lymphatic Filariasis (LF). Cambodia, the Lao People's Democratic Republic, Malaysia, the Philippines and Viet Nam have made significant progress with Mass Drug Administration (MDA) in recent years. China has been acknowledged as having achieved elimination by the WHO. The Republic of Korea is in the process of documenting the elimination of LF as a public health problem and is to submit a request to WHO for its verification. Mapping in Brunei Darussalam indicated to have very focal areas of low level infection which may not require any MDA. This scenario auger well with recent advances in the Global Programme with an increased interest in Neglected Tropical Diseases (NTD).
