Another of Carlos Slim Foundation projects is the one that, in alliance with the Carter Centerestablished the Onchocerciasis Elimination Office for the Americas.

Carlos Slim Foundation joined the initiative both in terms of technical capacity and resources, and in recent years has achieved the verification of the elimination by the WHO in Ecuador, Colombia, Mexico, Guatemala and part of Venezuela. As a result, the disease now only persists in an area located on the border between Brazil and Venezuela, called Yanomami.

The idea is that by 2018-2019 onchocerciasis will be declared eliminated from this area and, therefore, from the American continent. The model also seeks to help eradicate the disease in Africa.
