All You Need To Know About Lymphatic Filariasis

Lymphatic filariasis (LF) is a neglected tropical disease (NTD) caused by microscopic, thread-like worms. The adult worms only live in the human lymph system, which maintains the body’s fluid balance and fights infections. LF is spread from person to person by mosquitoes.
People with LF can suffer severe and even permanent disability. Affected people frequently are unable to work because of their disability, and this harms their families and their communities. LF affects over 120 million people in 72 countries worldwide. You cannot get infected with the worms in the continental United States.

The Impact of NTDs

Neglected tropical diseases (NTDs) are a group of parasitic and bacterial diseases that cause substantial illness for more than one billion people globally. Affecting the world’s poorest people, NTDs impair physical and cognitive development, contribute to mother and child illness and death, and make it difficult to earn a living.

LF’s Devastation

Lymphatic filariasis is a leading cause of permanent disability worldwide. Communities frequently shun and reject women and men disfigured by the disease. Affected people frequently are unable to work because of their disability, and this harms their families and their communities.

Treatment for LF

Experts believe that lymphatic filariasis can be eliminated globally. The elimination strategy is based on annual treatment of whole communities with combinations of drugs that kill the microscopic worms. Hundreds of millions of people are being treated each year.
