Lymphatic Filariasis in the Americas

Photo: A mosquitoe.Lymphatic filariasis (LF) is a disabling parasitic disease caused by worms that are spread from person-to-person by the bite of infected mosquitoes. More than 120 million persons are infected with LF, a disease that can be eliminated. CDC and its partners provide assistance to Ministries of Health to protect people from LF through community mobilization, distribution of effective drugs, and program monitoring and evaluation, with a goal of eliminating LF from the Americas.

With additional effort and support for evidence-based, cost-effective strategies that we can implement now, we can eliminate LF from the Americas. The information below provides a snapshot of the context and background for this priority area.
