Brazil: Lymphatic filariasis eliminated as a public health problem
Earlier this week, the World Health Organization (WHO) announced that Brazil has eliminated lymphatic filariasis as a public health problem, joining 19 other countries and territories in Asia, the Middle East and Africa achieving this milestone.
Lymphatic filariasis, commonly known as elephantiasis, is a debilitating parasitic disease spread by mosquitoes. For centuries, this disease has afflicted millions worldwide, causing pain, chronic, severe swelling, serious disability, and social stigmatization.
Over the past few decades, Brazil has implemented integrated actions to eliminate lymphatic filariasis, including the development of a national plan to fight this disease in 1997, the mass distribution of antiparasitic drugs, vector control activities, and strong surveillance, particularly in the most affected areas. With these efforts, the country achieved the end of disease transmission in 2017.
“This milestone is the result of years of dedication, hard work, and collaboration among health workers, researchers, and authorities in Brazil”, said Dr Jarbas Barbosa, PAHO Director and WHO Regional Director for the Americas. “Brazil’s extensive and unified health system, coupled with solid specialized laboratory expertise and robust surveillance were essential to interrupt the chain of transmission, inspiring other countries to advance towards the elimination of lymphatic filariasis and other neglected tropical diseases”.
