Lymphatic filariasis is currently found in approximately 80 countries. Over one billion people around the world are at risk of LF infection, and more than 120 million are already infected. Countries where LF is found are mostly in the tropical and sub-tropical regions of the world. They also are among the world’s poorest countries, as LF transmission is closely linked to poor sanitation and poor housing quality.

This section gives an overview of the geographical range of lymphatic filariasis, with links to countries endemic for LF. It explores the progress made in countries with active programmes and the challenges of establishing programmes in other areas.

Countries Map and List
A map and listing of countries where LF is found.

Moving Forward
This section contains more information about countries with active LF elimination programmes. These countries are involved in mapping the distribution of LF, implementing mass drug administration to combat LF, and/or offering disability management services to those afflicted with LF.

Starting Out
This section contains more information about countries with LF that are just beginning to form their national programmes. It discusses some of the challenges in starting programmes, including funding shortages, civil unrest, and educating policymakers about LF.

Success Stories
While LF elimination takes a concentrated effort of key actors, resources and social mobilisation, it is possible. This section highlights successes, big and small, from countries that are formerly endemic, those with current programmes and those with incipient programmes.
