  • Within the first eight years of the worldwide elimination program, 1.9 billion treatments for LF were delivered to more than 570 million people in 48 countries
  • 6.6 million newborns are now protected from becoming infected with LF
  • The economic benefit of the first seven years of the program is estimated at US $24 billion. The full economic benefit could exceed US $55 billion
  • Onchocerciasis, and the debilitating blindness it causes, has been eliminated as a public health problem from ten West African countries
  • Onchocerciasis has been eliminated in 11 of the 13 major areas where the infection was being transmitted in the Americas
